I would just like to say that thanks to everyone in this thread I now have a JAZZ-ff
Have it paired with a Yamaha DVD-S1800 SACD player as the source and driving a pair of modded Denon AH-D2000's. Really couldn't be more satisfied with it, finally brought out the bass in the phones I've been missing all these years and the clarity increase is noticeable. Do now notice that the bass response on the phones is not as good as I thought they were before though....arrgh.... you don't have to point out the faults in my phones JAZZ-ff, they were near perfect before you came along! LOL... Have a pair of T50RP Mark III coming in early next week, which is also one of the reasons I went with the JAZZ-ff... so will see how that goes soon. And the Massdrop Purplehearts are going to replace the Denon AH-D2000's...so there should be some tighter bass in the future.
Meier-Audio will always be on my radar from now on.
