Sort of. I borrowed Ipodpj's pair and plugged them into mine for about five minutes, then switched over to the Moth for another five or so. I liked what I heardwith the Zana, but please keep in mind the amount of time I spent and that this was under meet conditions.
The good news is that I'll order a HD-800 on Monday. I plan to spend a few minutes evaluating it when it arrives. The Zana is a priority, and I'll post impressions.
As much of a tube head as I am, I have to admit that the HD-800 really impressd from HeadRoom's amps. I just got a Beta22 backplane - I'm going to have to put that together for the HD-800. I'm sure it'll work well with tubes, but it sounded damn good on solid state, so I'm going to put one together.
