Tom Tutay Transition Audio Design Preamp

Just looking for some info and thoughts from owners or people that may have heard his preamp.
Admittedly ... not me. But I have posted a number of comments about Tom before. Search the Forum.

Tom is a great guy and a solid tech.

Good luck.
I just bought and installed a pair of the 1570.  Mine is # 19 of 28 produced.  Holly Cow.  They just keep asking you to turn them up, and the higher you go, the better they sound.  Don't take that wrong.  They are amazing at low volume, their is just no fatigue with them.  Clarity - Wow.  Tonal Balance - Wow.  All around the best amps I have had in my system.
Tom Tutay built a preamp for me in late 2003 in my Precision Fidelity C8 chassis as the C8 had gone south.  It is a 12AX7, 12AU7, 12AT7 dual mono design with an external power supply.  It is awesome and still running strong in 2016.
Met him one time,honest person ,very knowledge about tube amp and preamp.
but never use his product,seem very rare in the market,but never hesitate to try if show up.

I still have my amps.  I had to do a bit of tweaking to get what can be had from the amps.  Tom has a good design, but he is very cost conservative in some critical areas I feel he should not be.   In particular I changed the caps on the signal input from some crap to VCaps and Jupiter Copper Foil Beeswax.  I also change the signal cable to higher quality and moved it out of the amp so it was not affected by all the noise in the amp.  I also changed the power inlet, RCA inlet and speaker jacks.  The change was incredibly significant.  Incredibly.  These amps are pretty stunning.  They don't have the balls and kick my CJ had, but they are much more accurate and tonally balanced.  Very pleasant to listen too.
