Review

 

Many of our customers use Tom Evans Audio Design phono stages. All sound great. These units are priced fairly, carrying a lot of value to audiophiles. All our customers think highly of Tom’s products. So, I decided to represent Tom and offer his great products to you.

Tom is a very nice man, with two kids. He began his electronics career in defense industry. In 1989 he went back to his first professional love, building high quality and great sounding hi-fi gear. Tom always has time for his representatives and customers, explaining all the details of his products in detail. He takes great pride in his name and the products he produces. Tom’s Hi-Fi gears are so good that he called them Tom Evans Audio Design.

Tom Evans manufactures phono stages, preamps, power amps and speakers. Most information below is copied from Tom Evans Audio Design website by permission.

Review below is by a customer of ours Mr. Paul Folbrecht.

“I’ve been using a Tom Evans Audio Design Microgroove +X for about the last three months. I consider it to be my last phono stage. (I hope I’m serious this time, and three months is a long time to go without having any desire for something better or different – at least for me.)Discovering Tom Evans gear was a bit of a revelation for me, that began last year. I had read of it but never heard it – after all, it’s not very easy to hear (the phono stages are easier to come across than the Vibe/Pulse and the Linear A). I started with a used Linear A, and was very impressed with that piece: it had an uncanny ability to unravel detail (including microdynamics) against an absolutely black background, and was spectacularly “fast” and extended as well. Of course, those things in itself are not too mean a trick – a lot of good (solid-state) gear can do that. But what the Linear A did that did set it apart was being as fast, quiet, and detailed while simultaneously having *full* tonal saturation and *never* sounding the slightest bit edgy, or bright.

I then added a Vibe/Pulse (Lithos 7 version, bought used from the same dealer) – and it made an even bigger difference to the system (over the highly-regarded tube line stage I had been using). It was the Vibe/Pulse that was really a game-changing piece of equipment for me: a blackground blacker than I had ever heard before, with quite stunning macro dynamics, and full and complete tonal saturation with a lovely, perfectly smooth and rich midrange and treble. After using it for several months, any tubed preamp was just too slow and veiled for me. Prior to that point, I had never found a solid-state preamp I preferred to even a mediocre valved unit. I’m not saying they’re not out there – I’m sure very prices MBL and other solid-state gear can pull of proper tonal saturation without being edgy – but I do believe it is generally VERY expensive to do it.

At this point I decided I wanted to go “the full monty” with a Tom Evans phono stage and that I should buy a new piece to support the company. I decided on the middle-of-the-read Microgroove + X after reading reviews. (I have seriously toyed with abandoning vinyl altogether, and done so for short periods, so I didn’t think a greater expense was warranted.)

I placed the order through local dealer SORAsound (great to deal with) and received the unit after only a few weeks.

After being plugged-in for only a few hours, the unit’s potential was evident, but it did seem to take a few days to display what it’s really capable of. Once it had settled down, I was quite thrilled, and amazed – it really exceeded my expectations.

It was the signature Tom Evans sound – fast, neutral, completely extended, but tonally pure and harmonically complete, with perfect balance – to an even higher degree. (After all, the line stage is providing something like 12 dB of gain while the phono stage is at around 70 dB! I guess it’s hard to argue that the phono stage is not the most important part of a vinyl amplification chain.)

My analog setup is a Basis Ovation table, early TriPlanar arm, and Ortofon Rondo Red cartridge. (Yes, the cart is the bottleneck there in terms of cost, but it doesn’t really sound like it!) I had on-hand with the Microgroove +X a well-regarded tubed phono stage (with SUTs for the MC gain stage) that retails for about $6000 (almost three times the TE’s price). The tubed unit was also *very* good, and they were surprisingly close not only in overall performance but in sonics, but I did end up preferring the Microgroove. It had a substantially lower noise floor and was audibly more extended, although the tubed unit was very good in both regards too. The tubed unit was more “lush” in the midrange but I came to see that as a coloration and preferred good recordings without it.

That’s about it. Like most Tom Evans gear, it doesn’t really look like it’s worth the asking price and it’s so light that thick interconnects can lift it, but, well, who cares. Tom is, I think, proud of the fact that he refused to market “audio jewelry”, and isn’t it more sensible to put the money where it counts? (I’ve come to like the understated but purposeful aesthetic of the Vibe, but the Microgroove is so tiny I hide it behind the platform the line stage is on anyway.)”

Phono Stages

Tom Evans Audio Design phono stages include:

The Microgroove ($1,050) uses high grade silicon. The signal path is DC coupled. Built as a steereo amp powered by by standard industry voltage regulators. Like all Tom Evans phono stages, Microgroove can be configured to suit any moving coil or moving magnet cartridge. Great entry level phono stage upgradable to The Plus.

The Microgroove x ($1,192).

The Microgroove plus ($2,100) is a stereo phono-amp that has one of Tom Evans’ Lithos 7 Class A regulators in place of the standard industry regulators. This improves the sound significantly, lowers the hoise floor, faster risting and falling edges of notes highlighting the spaces between them. John Cage would have had a hay day.

The Groove ($4,000). This dual mono phono-amp uses one Lithos 7 regulator per side to supply power to each mono signal path p.c.b. All resistors are Holco precision metal film. All silicon is premium grade. The regulators are powered by a dual mono mains power supply. Since its launch in the UK, it has become the industry standard. The Groove can be upgraded to the Plus spec.

The Groove x ($4,725).

The Groove plus ($7,600). In this design the mains pcb has been replaced by the Lithos 6, a complex class A regulator (as used in the pulse power supply). Its outputs then feed the dual mono Lithos 7’s on the signal pcb’s. The external mains supply box contains a 70 watt transformer designed and manufactured in house. This transformer has an electrostatic screen to remove any R.F. noise, then rectified, smoothed, and regulated before leaving the box and heading for Lithos 6. The ultra low noise and distortion of this product provide audiophiles with the greatest possible dynamic range and resolution available.

The Groove+ SRX ($8,900) has adjustable load and gain. The Groove+ SRX,in addition to the loading pcb has a front end gain stage that has 50% less noise and distortion than the Groove and Groove+.

Upgrade of Microgroove to Groove Plus ($4,600).

 

Tom Evans has been making his Groove phono stages for some time now, the anniversary in this particular model’s name refers to 20 years of them and that occurred in 2010. Having been there at the start with the Michell Iso, which was effectively the first Groove and shared the black acrylic case that continues today, it doesn’t seem like 25 years but you can’t argue with a calendar. Tom’s shtick is that the best way to achieve true high resolution with vinyl is to lower the noise floor on the phono stage, the quieter this crucial part of the amplification chain is the wider the bandwidth and the more you will be able to hear. He advocates spending more, a lot more on the phono stage than the cartridge because no matter how good a cartridge is if the amplifier is noisy you won’t be able to hear what it’s doing. I have to agree, in fact I once took an Audio Note Japan stage (about £2.5k at the time) to a friends house who had a £60 moving magnet on his Thorens turntable, the improvement was staggering, the extra resolution revealed more music than you would imagine a modest front end could produce.

The reason for this is the level of gain that a phono stage has to apply to the signal in order to bring it up to a level that a regular amplifier can work with, in the case of a moving coil cartridge it’s in the range of 600 times. Which means that any noise in the gain stage is amplified by this amount as well, so a good phono stage needs to be somewhat quieter than the apocryphal mouse. For the latest range of Groove phono stages Tom has upgraded the silicon that achieves this amplification to what he calls Lithos 7.4, this has prompted a MkII series across the five Groove stages in the range.

What Lithos 7.4 has achieved in measurement terms is to reduce distortion and increase dynamic range compared to earlier models (existing Grooves can be upgraded to MkII). Tom likes to point out that dynamic range doubles and distortion halves as you move from one model to the next in the range, which would suggest that the entry level Micro Groove X is pretty noisy and distorted but I doubt that is the case. Not if the midrange Groove Anniversary is anything to go by at least, it is I suspect the quietest phono stage I have ever used but it’s far from the most expensive.

 

The other change brought about by the move to MkII is the introduction of adjustable impedance, previous Grooves have been factory set at one impedance and while you could specify what this was it was a bit limiting if you changed cartridge. Now there are dipswitches on the back panel that are relatively easy to access; some stages have them inside, others underneath. Here there are eight switches in parallel that have an inverse logic to their operation, the more you turn on the lower the impedance, so switching them all on gives 112 Ohms, all off 1kOhm, with seven steps in between. Once you have grasped the basic tenet of the approach it’s easy to experiment with loading, and surprisingly easy to figure out which gives the best result once you start listening to the timing and the interplay of musicians.

With the Rega Apheta 2 (on a Rega RP10) which specifies 100 Ohm loading experimentation revealed that the Groove Anniversary’s 250 Ohm setting initially gave the best leading edge definition, power and cohesion of the various instruments on Tom Waits’ Swordfishtrombones (Asylum). The track ‘Underground’ has some superb musicianship and this stage makes each player’s contribution easy to follow whilst presenting the ensemble as a perfectly integrated whole. You can appreciate the timbre of the heavy tympani and the tiny sound of a plucked ukulele, not forgetting the glorious vibe playing of Victor Feldman. The space created by reverb on the following track ‘Shore Leave’ is massively evocative as is the percussion and terrific guitar break, all of which is presented in a full width image that breaks the outer bounds of the loudspeakers.

I put on Burnt Friedmann and Jaki Leibzeit’s Just Landed (Nonplace) for a bit of low end action and found myself enjoying the tune rather than the sensation of having my internal organs vibrated. Here the emphasis was on the sound of the instruments and the melody rather than the crunch, which made me wonder whether the higher than recommended loading might be affecting the balance. This turned out to be the case, the higher the load (on this cartridge at least) the less low end power it delivers but the faster the transient edges. Experimentation with a few other bass strong records made a case for bringing it down to the 200 Ohm setting. It’s nice to have such close alternatives.

With the finesse of Jocelyn B Smith’s direct to disc cut Honest Song (Berliner Meister Schallplatten) the quietness of the Groove is made obvious by the way finger clicks are so clear in the background of piano and voice. The ‘air’ around the cymbals and the singer’s breath on the mic coalesce with the music to present a degree of realism that’s rare. Cymbal work is notable on a number of pieces and reveals an unusual degree of transparency but don’t get the impression that this is a lightweight filigree specialist. When the rhythm section on Patricia Barber’s ‘Company’ (Modern Cool, Premonition) gets going you know all about the power and pace. The double bass has a physical presence that is palpable but does not smear the voice and the acoustic it’s recorded in.

 reviewed a valve powered phono stage from a well regarded brand during the Groove’s tenure and made the mistake of comparing them. The result did not favour the valve stage one bit, making it sound noisy, smeared in timing terms and lacking in transparency. Valves cannot hope to be as quiet as transistors but people value the tonal richness they bring, I prefer to hear what’s on the record, the actual sound of the voices and instruments rather than what in photographic terms sounds like saturation. I also like the natural way that the Groove presents imaging, every record you play has a slightly different character which seems to be a logical result of the variations in recording venue and technique.

Take Leo Kottke’s Great Big Boy (Private Music) as an example, this is an acoustic guitar led band with voice that has an awful lot going on on tracks like ‘Jumps Up Running’. I’ve played this many times but had not been previously aware of the keyboard line, the Groove cleans up the background and brings a coherence to dense mixes that lets you hear right into them. It prompted me to listen longer and louder than I have for some time with this particular record, remember just what a great musician Kottke is thanks to the Groove’s its remarkably light touch.

Forget your Vendetta Research and Audio Research preamps, they may have legendary status but technology moves on and today’s silicon is infinitely quieter than it was only five years ago, which means you can hear more music and less electronic intrusion through it. The latest Groove Anniversary is a goalpost moving phono stage that digs deeper into the signal and reveals so much detail across the board that you can hear right into the layers of multitrack recordings. It still doesn’t help the musically inept like myself establish the time signature of Steely Dan’s ‘Show Biz Kids’ (Countdown to Ecstasy, ABC) but it lets you hear how each of the instruments in the mix was played and the irony of the lyrics.

Calm is the good word when describing the Groove, it takes everything in its stride and no matter how dense the material never seems to struggle. It’s a very low distortion conduit to the musical joy that vinyl offers. It won’t turn mediocre recordings into amazing ones but it will let you hear more of what has gone on in the studio or on the stage when they were made. It gets you closer to that place in time and space where the magic happened. The only disconcerting thing is that there are several better stages in the Tom Evans Audio Design range, you have to wonder if there are enough superlatives to go round?

Sure is.

 

Not sure, its the 20th Anniversary edition, did they do a Mark 11 option or is that the Mark 11 option.  Any ideas how I can tell. As Tom does not even give you a booklet on it. I think it came with a sheet of paper with notes on settings but it was pretty basic. 😂

I see in one of your photos (I assume it's stock given the watermark), it identifies the model on the back plate of the PSU. So maybe check there. Cheers.

Yes it is reading the article the Mk2 comes with adjustable impedances

however the power supply has only the Groove anniversary written on so will read up a bit more. Still selling as Mark 1 at this stage

 thanks Adam

 

Confused?? from article... I think I may have a Mark 11 unit and a Mark 1 power supply. Anyone have any confirmation either way?

      Although Oval 10 is the best choice for high current applications, it performs equally well with low current analog and digital equipment too. WattGate 320 IEC and WattGate 5266 connectors are used with this power cable.
      Why You Need the Power Oval
      When people design power cords they use massive cable to reduce the noise voltage on the cable. The noise voltage that occurs on the cable is related to L (inductance) and di/dt (the rate of change in the current). You can reduce L by using larger gauge wire but you don’t get much bang for your buck because it is a log function. What this means is that as you keep increasing the gauge of the wire you do not get much improvement for your effort. This is why you see people using very heavy and stiff wires in power cords. I have seen some power cords that are so big and stiff that the CD player connected to them is lifted off the ground.
      What we have done at Analysis Plus is use computer simulation to optimize the design of a power distribution system. What we discovered is our patented hollow oval design provides a low L cable without having to use stiff and bulky cables. Our cables have a super low noise voltage to reduce the background noise to a minimum. This is extremely important during quiet passages, if you want to hear subtle details (this is very important for classical music fans and for other lovers of live music).
      The other thing people don’t realize about low frequency noise is that the thin aluminum shield found on many power cords does nothing to reduce this problem. The best way to reduce low frequency noise on cables is to reduce loop area. From our computer simulation and measurements we found our patented hollow oval cables does a great job at this. We have the lowest noise voltage we have seen with our hollow oval design.
      For higher frequencies our silver-plated copper braided shield does a great job. We used an open braid design that works much like the window on your microwave oven. You can see through the window but the radiation stays where it belongs.

      IsoTek is an English company making award-winning power optimisation products for hi-fi and home cinema systems. You can increase the performance of your audio and video components and the IsoTek EVO3 Premier Mains Power Cable is a highly recommended upgrade.
      Overview
      Before we discuss the product details of the EVO 3 Premier mains power cord, lets review some of the reasons why people like us and our friends at IsoTek really believe you need to seriously consider upgrading your mains power cords.
      The standard black mains leads supplied with your audio and AV components is designed to do a basic job at the cheapest price and absolutely no more. It doesn't matter on a kitchen appliance, but they lack the quality of materials and construction needed to protect the integrity of the electricity feeding your system, thereby degrading performance. Outside interference from Radio Frequencies (RFI) and Electro Magnetic Interference (EMI) can't be seen with your eye, but your mains power cable is just like an antenna picking up this unwanted noise. The first rung on the IsoTek ladder is to replace these power cords with products from one of the four different ranges based on the value of your system.
      Of course, you will get the best by choosing the top-of-the-range EVO3 Optimum mains power cord no matter what you've spent on your system, but realising that approach is not practical and would simply have most of you dismiss an upgrade, Isotek have manufactured a range of four mains power cables that all help reject outside interference but to varying levels. As you move through the IsoTek range the performance level increases, with an array of mains cables and power optimisation devices to suit any audio or AV setup.
      Premier: Part of the Discovery Series and for any component priced between A$500 and A$2,000. A simple upgrade that delivers great results.
      Sequel: A step up from the Premier mains power cable and nicely priced. Recommended for any component priced between A$1,500 and A$4,000.
      Elite: Part of the Performance Series and recommended for any component priced between A$3,000 and A$10,000. Extremely high quality materials used for construction given the price. The penultimate product.
      Optimum: Cutting edge in every area and essential when your system is more valuable than your motor car! Part of IsoTeks Ultimate range.
       
       
       
      4)audio Principe x2.  1 metre and  2 metre cables. for 1 metre and  for 2 metres. rrp is $269 a metre SOLD
       
      As per Audio Principe site:
      The Audio Principe “Signature” is the top of the range reference grade power cable designed to ensure maximum clean power transfer for demanding amplifiers and components.
      Heavy 14mm diameter shielded cable with 2.5mm2 pure copper conductors including mains earth provide extremely low resistance for maximum current flow.
      Braided shielding and inner metal shield give 100% coverage to provide protection against EMI and ensure clean power supply.

      Extra Info:
      It's been many a year since I ventured into the land of headphones and the DIY journey has been filled with wonderful discoveries. It's time to release some of these into the wild for others to enjoy. All these are at below parts cost and have been built and modified and modified again to obtain what I believe is their best sound.
       
      This is an interesting amp of which I bought from a fellow SNA member. It used 6j6 tubes configured in push pull driving a output transformer. I always had my doubts about output transformers and this amp certainly changed my views. For people who attended my latest "Brisbane headphone" GTG, this was the amp that was powering my Utopia with great effect. Currently fitted with some real nice Amperex tubes. I have plenty of different other tubes and if bought locally, I will work with the buyer to find a set that suits them perfectly.

It's time to release some of these into the wild for others to enjoy. All these are at below parts cost and have been built and modified and modified again to obtain what I believe is their best sound.
       
      This is basically the same amp as the other one advertised, apart for some major modifications.
       
      HT power supply has been totally re done. Far superior layout and power filtration (Rubicon and Russian PIO caps). This amp is whisper quite.  
      All components (excluding the toroidal transformer, output transformers and tube sockets) have been swapped out for better ones. Mundolf interstage caps, Rubicon filter caps, Hammond choke, Alps pot and plently more.  
      Silver solder used throughout.   
      Optimised component layout with internal shielding within case.  
      High and low impedance headphone sockets  
       
      A lot of time and effort went into this build with exception results. Currently fitted with some nice Russian tubes and I will supply 2 other sets so the new owner can change if necessary. Really sad to see this one go, but I would prefer it being enjoyed by someone than sitting around being unused. Comes with money back guarantee, if you don’t like like, post it back in original condition and I’ll refund you the purchase price. What more can you want.
