My current headphone Amp is a Graham Slee Solo W/ PSU1.
Headphones to date are Sony MDR-SA5000, Ultrasone Pro 900 and the Beyer DT880 '05/250.
you have two cans that are on my shortlist, sa5000 and pro900.
how do they perform with the solo?
i refer mainly to the common reported failings of the cans.
ie too much bass on pro 900, and too little on sonys ( + thin sound)
these are only what i have read, of course. your opinions would help me decide on next purchase.
