The A1 is a tube head/speaker amp (tube + solid state for the power amp) that I'll be purchasing soon: http://www.mav-audio.com/base/product/tube_magic_a1
I basically went on Headroom and found the best headphones under $500. I have the Audio-Technica ATH-M50 and am looking for a step up to be used (almost) exclusively with the A1 (whereas the M50 can be easily driven by iPhone or portable amp). I'm trying to decide between:
- AKG K702
- AKG K701 Quincy Jones (leaning towards this of the AKGs - thoughts?)
- Denon AH-D5000
- Senn HD-650 or 600
- Beyerdynamic DT770/880/990
I think the Senn HD650 gets generally the most positive reviews, but I'd like to hear anyone with tube experience speak on the merits of these different 'phones with a TUBE amp. Thanks in advance!
