Did you use two OPA627 on an adapter? What you describe sounds like what others have described while putting only one OPA627 in a socket.

I downloaded Creative's Console Launcher and put the X-Fi to output 96 kHz of sampling rate. Absolutely no hissing when I set music to pause and turn my Little Dot all the way up.

BTW I'm using OPA2604 right now because the DY2000 produced some hissing in highest notes. This OPA2604 doesn't sound bad at all with tube-amp.

I agree. The OPA2604 may not be the "top" pick, but for pre-out of the DAC, it works well driving other amps.

There is something wrong with my DY2000 too, I put it again in the Zero and it still has hissing or maybe distortion sound in upper notes.

I have contacted Lawrence about this, hope everything works out.

With the DV332, I hear a very noticeable difference. Everything is more relaxed, without the "flatness" and middle "glare", and it is also more dynamic and more controlled and deep in the bass, playing with bigger authority.

Why, was your nose hair affecting the sound?

well initially I had promised my self that i should use the stock opamps the first 100 hours.. but my patience is more or less non exciting. So. after 20hours with the stock opamps I have now changed to opa627 in the dac and 2xLT1364 in the amp section.
The biggest difference is in the bass region, which in my case using the stock opamps where more or less non existing. with the upgraded ops the bass i there, but still has some way to go..

got mine about 2 hours ago

sounds much better than i thought it would, i love this thing.

had to break out the audigy 2 zs plat. pro though because it arrived quicker than i thought and had no adapter for the x-fi

sounds great though, using DT770/80s

Yes indeed, it is tough to sit on your hands for 100hrs.
It's ok though. If the upgrade was mostly what you were after, then you'll just complete the 100hrs with different Opamps. If you get bored this summer, pop in the default Opamp and give a listen.

With the upgraded Opamps, and feeding the DV through the Zero, I'm not surprised. Several have commented in the past that the sound is more like a tube amp in the Headphone side. How many hours do you have on the Zero?

Hey man, I forgot what Opamps you are running in the Zero?
See ya!
