I think the higher speed ones run a little warmer than the others. I'm not worried because the Zero has ventilation.

#1 has OPA627's in the DAC, LT1364s in the Headphone board.
#2 has LT1364 in the DAC, LT1469s in the Headphone board.

I like the sound of both pretty good. #1 is for feeding anyone of my tube amps from my PC, #2 is for feeding my Vintage SPEC equipment from any of my digital sources. It sounds really great too.

I just looked at the temp testing data and they had 0 failures when testing them from 65c to 150c, which is like insane! I think we are ok.

The #1 and #2 are actual Zero units too! I like the sound of #2 and the added warmth of #1. The Zeros have given me a low cost way to connect up all of my different systems, which is a blessing.

No problem! It has one of the better signatures we have found so far. The low end goes way down, with punch and clarity; The mids are flat with a slight touch of warmth; the highs go way up, with clarity and detail. It works well with all types of music and it is very quiet.

In the MK1 portable, it has become the Opamp of choice over the LM4562. Combined or by it's self, it is a true performer.

My second one was smelling bad for about 10 minutes, then it was gone. I'm guessing yours is still running, so hang in there!

Okey, me and my dad had done some serious listning. THE built in amp in zero beats my DV. It's seperate instruments better and wider soundstage.

The built in amp of a less then $200 DAC/AMP beats the DV 336i with good tubes ?
Thats just crazy. Your on drugs !

I doubt the zero beats it on female voices. I hope anyways :P.

That is a very good point! This is how I am too. I suspect that there are many others like us, they just don't know it yet!

Hmmn, i think there is a limit on the amount of characters you can use in a search, as 'Zero' yields nothing.

I want to know how this fares against other popular amps as a headphone amp? I'm hearing great things about the pico and am thinking of pairing it with the Zero, but if it isn't much better then there is no point..
