Didn't you have the ODAC/O2 combo? Why are you then using the DAC1 when they measure the same?
...
Nah I'm just kidding with you!
I went from the O2 combo to DAC1 myself! Then I got a HD800. I thought like you that I was done for good (like the good and scientific objectivist that I was!) Then I LOL'd at the Vali hype that was going on. "They are so st000pid, omg tubes measure badder then my equipment." Well then I was gonna prove them wrong, so I ordered the Vali and was going to send it back the day after I got it! "OMG it has ringing! This thing is BAD and I should feel bad for even trying to listening to it!"
I was already getting the package to send it back when I started listening to it. I wish I could say that I had an ephiphany, but I didn't. What I did however, was sitting up all night listening to all my music, and couldn't get enough. And I didn't understand. Then I tried AB blind testing with the DAC1 HP out, with help from a friend. I could tell them from eachother every time, and each time I preferred the Vali. I didn't know right there why that was, but I can tell you now: it was because
the Vali reproduced music in a more accurate and natural way. I am not good with words about how things sound. But I am a drummer, and I know how a kickdrum or floor toms should sound in real life. The Vali got that more right then the HP out from DAC1. Easy as that.
Long story short, I gave up my
absolute objectivism and instead now embrace sceptisism. I am starting to build up trust against some ears, and while that can
change over time the best way to find out if you like something is to listen to stuff yourself.
I am really happy now with my rig, and you should be to! The real
star of the show is still the HD800. And even if it can sound different depending on what gear used, it's still sound like a HD800.
I dare you to try the Vali. It's cheap and you can send it back. The only real downside is that you might like it.
