Coincident Statement Line stage

Recommended Posts

I am not a betting man by nature, but sometimes the only way you can decide on a piece of audio equipment these days is to do as much research as possible and then take a punt. Such as the case when researching for a new preamp to replace my Supratek Cabernet Dual.  The Coincident Statement Line Stage  (CSLS)  kept cropping up as a seriously good linestage.

 

I concentrated on independent  reviews from Stereomojo , Enjoythemusic.com, and audio-activity.com and contacted the reviewers with a series of questions.  I finally emailed Coincident and received a speedy reply from Israel Blume, President of Coincident.  I am happy to report that this level responsiveness continues after the sale is made.

 

Pricing:

 

The CSLS price is $5499 US delivered door to door – customer pays for any brokerage and taxes.  If this was to be sold through a distribution and dealer network, the price could easily be doubled.

 

 


Features

 

1.     CSLS uses directly heated triodes -101D tubes in the active gain stage . No other tubes are used.

 

2.     There are NO capacitors or resistors in the audio signal path

 

3.     Volume control is by transformers. (There is now a new remote control model with conventional volume control)

 

4.     All coupling is by transformers. This means transformer quality needs to be top notch – and indeed it is. Coincident have their transformers custom made  by a specialist Japanese company using supermalloy cores.

 

5.     Power supply is massive and is capable of powering a 100 WPC amplifier. 

 

6.     Balanced wiring throughout– Although 101D’s are single triodes , Coincident have utilised balanced wiring throughout the line stage.  I have read a technical description on the internet about how this could be achieved but the official word from Coincident is - “Without divulging proprietary design topology, we use a completely novel and innovative technique to create a truly balanced circuit without compromising the purity of a single DHT tubeâ€.

Listening

 

Although there is a 200 hour recommended burn in time, out of the box it was apparent that this preamp is something special. The first thing I noticed was the focus, level of detail, 3D imaging and massive soundstage – it is simply in a different league to anything I have had in my system before.

The CSLS tonal balance is highly transparent and neutral which allows the natural timbre of the music to fill that huge sound stage. On well recorded music, violins for example sound naturally sweet and organic without adding any flavour. Overall the CSLS is more suitable to a wider range of music which can be sometimes compromised by distinct sonic signatures imparted by equipment.

 

 

The CSLS is very fast and dynamic – something not often associated with tube preamps. It has deep, extended and well defined bass without any hint of bloom that can afflict some tube designs. It seems eminently suitable to drive SS as well as tube power amps, particularly where people may have had concerns with the drawbacks of conventional tube preamps.

 

Downsides:

 

The CSLS has 2 volume pots and I was going to mention the lack of remote control could be a deal breaker for some. However, Coincident have now released a remote control version using a high quality conventional stereo potentiometer. It is the same price as the CSLS but apparently has a slight performance compromise that would happen in any case where conventional pots are used.

 

To nit-pick, I would prefer better marked or different volume knobs to make it easier to see the volume positions on both controls at a glance

 

Conclusion

 

It must be said that Coincident have done an outstanding job in bringing this 101D based preamp to a state of the art design.  It’s expansive sound stage, focus , imaging and transparency has set the bar very high indeed. If you have the opportunity to do so, have a listen and do the comparisons

Nice review and photos, Tasso. I'm guessing a decent L lens for esp that 3rd photo?

I concur with what you have written. I have also been on the hunt for an 'end game' preamp for the past couple of years. Have managed to try quite a number of preamps (both active and passive units, solid state and tube designs) on my system.

The CSLS has been my clear favourite so far. Both on my system and yours.

I just love how it makes good recordings sound so open, 3-dimensional and 'solid'. It doesn't really have that sweet syrupy rich (but slightly soft) tone, which I've found sort of common with tube preamps (esp DHT based ones). I found those things didn't work well with all the styles of music I listen to. Anyway, after having tried a number of other preamps and thinking I knew what a 'good affordable tube preamp' can do, I'm still quite amazed at how different the CSLS sounds to the rest, to be real honest!

After hearing yours, I knew I must have one for myself. Fortunately, I did find a used unit for sale while over in Adelphi, Singapore recently. I would of brought it home with me, if it would fit in my luggage. Have since made contact with the store owner and have purchased it. In fact, it should be arriving sometime later this week! :)

Thanks for the nice write-up and the pictures..... :thumb:

 

Just a quick query, (please do spare my ignorance), do you need to set the volume pots individually?  :confused:

Yes pulinap, individual left/right volume knobs. Bit of a turn off I can imagine for some.

Yes it is a bit of a turn-off as one has to match the exact levels of the two pots.... :confused:  

 

But I guess you get a hang of it as you go...... ;)

 

Nonetheless, a stunning looking amp....... :thumb:3

It isn't too difficult, as it uses a stepped 23(I think)-click switch behind each left/right knob. So say as you turn the left channel up 2 clicks (you can feel and sort of hear the clicks as you adjust), you would turn the right channel up 2 clicks too.

Hope that helps gives you and others a clearer idea :)

...pro camera, pro photographer, or pro both I suspect?

About the separate L & R volume controls...I did listen to the CSLS in my system and the absence of a remote control is something you can live with, just means you need to get up out of your chair occasionally which isn't such a bad thing!

Very nice review Tasso! Great photos too....! :thumb:  Exposure(s) looked either on stand or high iso (1600) with 1/30 - 1/60 at f2 - f5.6. I think the macro one aperture is about f2 or 1.8.

 

Maybe a review for Accuphase DP-700 too? ;)   Love that Accuphase..... :love

Tuyen, Chanh, Brodric

 

I used a Canon EOS 5D Mk 2 with 50MM 1.4 lens - It is  often overlooked but it is a very sharp and fast lens. Camera was hand held and photos would have been better on a stand but I couldn't find the mounting piece for my tripod. The capacitor shot was at 1/40th of a second, F1.6  at ISO 500 . The other 2 were at 1/50th second, F5 at ISO 1600. I would have preferred to use either of my Tilt and Shift L series lenses but these really need a tripod for shots like this. With those I could focus as per normal then shift the focus  plane to bring everything into sharp relief  without having to compromise the integrity of the picture with very small aperture. I am clearly not a pro because a  pro would not  compromise any photo to  be displayed  because of convenience.

 

Review of Accuphase isn't a bad idea - maybe after Melbourne show and I'll find that tripod part!

You could borrow my gears, tripod, flashes, umbrellas, Sekonic meter,.... elec-trigger and filters. They are collecting dusts while my priority change to audio. :D

 

Edit: I've just realised you and I are from different camp but tripod's hardware are common. Love Tiltshift, which focal lenght did you have? 24mm, 45mm or 85mm?

Wooo, 50mm 1.4 prime.  nice!   I really enjoyed using the super cheapy 50mm 1.8II, back when I had some gear.

 

Anyways, who's keen for another preamp GTG? :)

What's your CLSP arrived? If so, maybe Tasso could bring over his DP-700 to sweeten the combo?

Keen? Definitely am....

The 2 pot thing isn't a real issue once you  can live with no remote. Both pots  have a very high quality feel about them and  are a pleasure to use. As Tuyen mentioned it is very simple to match volumes but there is always the remote control model if RC is a must have item.

      Part 1.
      I spent a very pleasant afternoon in Carlton yesterday, indulging in hifi gear and experimenting with the sound of 2 very good good preamps.
      To make the day interesting I packed up my CSLS, replete with PSvane 1:1 replica tubes and made the trip down from Ballarat. The system set up at Carlton AV is very similar the one at my home, and reassuringly sounded very familiar to me, despite the different room. Carlton have the MB2ses, hooked up with ARC ref 250 monoblocks, the ARC ref 5SE and the ARC CD9. Balanced cabling throughout, and there was some serious room treatment, although the room was a little small.
      For my tastes, the CD9 was a little less airy and less detailed than the PSAudio DirectStream, but it served the purpose for the real test which was the preamp comparison. The ref 5SE was already warmed up and waiting. It is a beautiful piece, in keeping with traditional ARC design methodologies. It sports a dizzying array of both balanced and unbalanced inputs and outputs. A potential owner would not run out of connection options.
      The CSLS by comparison is quite a brashly simplistic design; polished steel and outboard tubes. Twin volume controls are transformer based, and there are only 1 set of balanced inputs and outputs, although multiple unbalanced options are available. It's other points of difference are the unique 101D tubes used for amplification, and the lack of any resistors and capacitors in the signal path.
      The ARC would be the one I'd buy based just on looks alone. The controls are smooth, svelte and the digital display is usefully large and clear. The AudioResearch label also inspires some significant degree of confidence in support and resale value, but the price tag next to it read $16995. The CSLS although somewhat rugged in its own right, with chunky dual volume knobs and flick switches. Quite reasonably you can land one in Australia for around $6000, depending on the exchange rate. You must deal through Israel Blume to order one, and there is no local support. The PSvane replica tubes were an addititional $600.
