been playing my mkiii for a little while and i think i've hit on a couple combination of tubes i like.   stock power tubes + GE JAN5654W stock GE drivers are too dull for me. Amperex 5654 are really nice but a little thin...

Did you remove the filter? And are you coming directly off the DACs instead of off the PCB? I know that's an ugly picture but it shows the missing filter and the silver wire go over to each DAC fore output ...    

Not sure if this will make the difference but early on i did a mod to clear up some distortion. Dropping the resistance on input to the dac board to 1.2k using 2k + 3.3k on the board I had.

i has the filter and is worthy without any mods ... after 200 hours of burnin.

I get it. Which means if I put my last 110ohm resistor inline, meaning using 110 instead of 47 in the places you indicate, I will have both iput working and isolated but at 110R.   Did you ever try 100R before settling on...

Steve,   I am a curmudgeon. True enough.   Yes, I did see a quick mention of OPT. I can only say that bass is profound are here. I do not have cutting edge stuff, just Paradigm Studio things with a bunch of drivers...

a comrade informed me 6moons Steve Marsh finally completed the Teradac review. I don't think much of it but here it is: http://6moons.com/audioreviews/teradak/chameleon.html   ahem ... no bass? harumph. and why the...

rhodes, getting ready to do the 74HC04 mod and i have a question. so the two 47ohm resistors, are they in series? if so why can't we keep the 100ohm resistor in place as it adds up closely to what the two 47ohms...

marcelnl, i just gave you the reasons. ;-)   anyway, there is a very nice inexpensive transport i bought from little dot that has removed the nasty periodic noise bursts i was getting from my nad cdp. the little doc cdp_1....

one reason the change the output stage with tube buffer or transformer is to gain advantages from galvanic isolation and/or impedance.
