Just got this up on to YouTube in HD. Hope you guys like it and please share/comment. I will update this thread with my impressions in the near future. Stay tuned.
I've been listening to it on my HD800. I have to say and really hate to say this. It's a GREAT match! I hate to say it cause everyone reviewer of the HD800 said this and the cost of this is almost as much as the HD800. I really didn't want to buy it cause it cost a lot, but the PS Audio GCHA sounded like crap with the HD800.
This amp is actually really pretty good paired with Beyer DT990/600 Ohms. It's a well balanced amp and I think it is worth the high price.
I got a Cyber Monday deal on it so I didn't pay retail, but it is still not cheap.
