Technical Brain TB-Zero/int Review

Recommended Posts

Damn it Terry!  I can get a decent level of clarity out of it but I can't replicate that soundstage that we heard at your place.  2D is OK but 3D is mostly absent and I'm not sure why.  It may be that I have too much gain, or at least that's the way it seems.  It's also possible that the room is just too small, but I don't like that possibility so I'm choosing not to give it much consideration.

I'm going to take a break from audio and do a little catching up on TV.  Maybe after that I'll be able to come up with something.

Interesting mate. As good as the Lenehan’s are they just might not be up to the sound staging that the Vienna’s have. 🤷‍♂️

The rooms do look vastly different as well, could be a massive contributor.

I have encountered the problem of "my room seems to be too small for the sound stage to breath" a few times in the past.  That could be the case now as well, it's difficult to be sure.

I'm guessing Terry's room would be somewhere between two and two and a half times the volume of mine.  

 

I have an idea but it's getting late so I'll see what I can find out tomorrow.

I agree speakers can make a huge difference to sound stage.

More than just speakers I think.  The Consonance Droplet puts out the usual 2.3V signal, I say usual as that is the usual for Consonance players, they don't use the line level standard of 2.0 volts.  So balanced outputs are 4.6, not 4.0.

That extra gain worked wonders for the Exposure 2010S2D at my place and made for an astounding sound stage at Terry's place but it isn't doing me any favors in my smaller room with the TB.

  

I improved things massively by shifting back to unbalanced inputs (via adaptors) between the Droplet and the TB but I've still only got about 70% of that 'astoundingness' level.  Now that's a pretty good sound stage but it isn't anywhere close to the sound stage through those Vienna Acoustics of Terry's' and, as I believe many of us have said once something has been heard it cannot be unheard and 70% isn't just a poor second place, it's more of a piss-poor 5th place (no medal, just a crappy ribbon for participation) and that isn't easy to live with when you now know what the amp is capable of.

 

I've been running the Sansui 907NRA for a bit to compare against and I found that it wasn't a fan of the balanced inputs either, it lost that relaxed feel that I love so much about it.  That's what convinced me I needed to shift back to unbalanced inputs.  

 

The TB is sounding very nice, that impressive clarity is there but there is also just a touch of hardness in the treble and I'm pretty sure it's gain related.  You'd think that could be fixed by reducing the volume on the droplet, but it seems not.

I think it's time to start fooling around with ICs again.

Then doesnt that rule out gain? You are left with speakers, speaker setup, speaker cables? room and yes I am going to "go there" power:blush:

And out of all those I would guess that the speakers probably make the biggest difference. Perhaps Terry could throw the speakers in the back of a car and head to Cafad’s place.

Not the way I hear it.  

Room is a big thing here, mine is less than half the size of Terry's so my listening position is much closer.  So in my lounge it sounds like there is too much gain.  The sound is solid and clear but a bit too fast and a bit too hard, particularly in the mid range.  By using the unbalanced in this effect decreases.  It seems like gain is the problem to me.

Or the speakers just don't like the TB, that's another possibility.

Another possibility is difference in the tubes.  Most tubes of the same brand & type can vary considerably in gain and conductance.  There could also be different brands or alternative tubes being used?  It appears the Droplet CDP5.0 uses Sovtek 6H30's as stock tubes.

 this is something I experienced when I had to give up my dedicated music room and move all my gear to the much larger lounge room... it was like a 200% improvement even though a non dedicated space... room makes a lot of difference. things like sound staging ... air... clarity and detail all took a step up...

 

quite possible a gain or speaker is match as well :)  only ways to know would be to take your speakers as well next time to terry :D

So when you say gain, what sort of gain? Is it from the room?

I don't really know, possibly caused by my sitting so much closer to the speakers than at Terry's.

Ok is the room very "live" sounding, ie a bit reverberant. Do you have any treatment at first reflection point? If you are getting a lot of sound reflecting off the walls that will usually tend to spoil image depth. If the room is smaller the reflection is closer in time to the original sound from the speakers and that will cause all sorts of problems, too much mid freq energy is one of them.

 

The reason why I am interested is I have been chasing image depth in my room.

      Item: Melody H34 Signature Integrated Amplifier
      Location: Melbourne
      Price: $1800
      Item Condition: 9/10
      Reason for selling: Surplus
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info:
       This is my very first amplifier into the world of tubes and valves. A lot of time and money was invested in tube rolling to get the right synergy out of the amplifier with the right tubes. Original valves have been replaced with Mullard reissue El34, Mullard 5AR4, Brimar 6SL7 and Ken Rad 6SN7. Over $600 worth of tubes there alone. Amplifier is in excellent condition for its age and presents itself beautifully in its deep piano black chassis. Will come with its original double boxes and manuals. Inspection and sound will not disappoint.
       
      Extract from the internet

      MELODY H34s ASTRO BLACK Favorite tube of many music lovers is the EL34 which excels at tone. The tonality of the EL34 makes it also popular with musicians using stringed instruments, especially guitars. The most popular amplifier in the Melody range and winner of many awards the Melody H34 Signature offers fantastic sound quality at a price that seems unbelievable. With a full size chassis in piano black finish and retro styling it is a statement product in quality and style. The 25mm thick front panel contains three large solid aluminum knobs which control power on/off, volume and four RCA inputs. The volume knob controls a stepped resistor array with 24 positions. This ensures precise channel matching and maximum sound fidelity. The power tubes are four EL34 which deliver 40 watts of effortless power. This allows it to drive a wide range of loudspeakers with ease. The input and driver tubes are 6SN7/6SL7 and the amplifier has full tube rectification provided by the 5AR4 tubes. All the internal wiring is done by hand point to point with no circuit boards at all. This is the traditional way to build a long lasting amplifier with maximum sound qualities. It permits easy servicing and parts replacement or upgrading which modern solid state circuits with surface mount devices to not allow. At the rear are three oversized and shielded transformers with a power transformer in the centre and an output transformer either side for the left and right channels. Melody’s know how has delivered an amplifier that is powerful, delicate and with a depth of tone that makes it very beguiling. This amplifier can be muscular at one minute yet delicate the next, extracting minute details from the music. The sound stage is wide and deep and the bass is extremely realistic. The bass however is not dry or truncated, like many transistor amplifiers. It delivers information in the bass registers with plenty of feeling. The H34 Signature is an amplifier that music lovers will enjoy, not only for its sound but for the unbeatable value it offers.

      Item: Luxman 505u Integrated Amp
      Location: Adelaide, SA
      Price: 3000
      Item Condition: Excellent, mint condition
      Reason for selling: Purchased a Devialet 220
      Payment Method: Pickup - Cash, Paypal, COD Only.
      Extra Info:
      Two things to note:
      The remote is dodgy with its Volume control; over the years I have either changed volume manually or use a DAC/preamp.
      I imported the 505u direct from Japan so it was assembled for the Japanese market and set to 100volt mains electricity. Therefore it comes with a Kashimura TI-20 step-up transformer (photos attached). There has never been any issue playing it here in Adelaide.
      The Luxman has been in daily use since July 2010. It has always worked well and given me great listening pleasure.
       
      I have attached a User Manual and Brochure. 
      The 505u has a phono input with both MM & MC selections.
      The amp can be used as a pre-amp only or power amp only.
       
      The 505u weighs 21kg. The transformer weighs 4.5kg and its dimensions are 170x135x100mm.
      I will post both items if there is no buyer in Adelaide for pickup - postage costs would have to be checked and agreed to. 
      I still have the original box available for transportation.
