That Phonitor looks fantastic! Made in Germany, good finish. Could be a goer. However, how does it sound in a good hi-fi set-up? (I'll checkout the Head-Fi posts for more info on it too - I see you have one for one sale) Your unbiased opinion... is the Phonitor a great match for the HD800? Also, the SPL website states they use OP Amps. Gggrrr, not happy about that. AND, is all that pro-use, whizz-bang signal processing done digitally? If so, that's a no-no for gogo...
I looked at the Apache. Nice bit of kit, but I don't need a preamp. I would rather spend the extra coin on a better headphone amp. The other solid state offerings from Emmeline seem pitched at the desktop market. Shame, because their tube amps look pretty hot (no pun etc).
From the comments, I'll scratch the M902 and the King Rex from my list.
Thanks for the input.
