HD650 aps balanced
Ety ER-4s, ER-6p
Been there, done that:
Current Grado line-up; sr-60 thru GS1000
HD600, HD580, HD595
AKG K701, K501, K340
Tried but didn't buy:
UE-9, D5000, Beyer line up.
Not much for headphones (that I can realistically expect to own)
Maybe HeAudio 1.2, distant maybe ESP-950, HE60 if ones shows up at the right time. R10 and HE90 would be awesome, but so would dating Sandra Bullock
I committed all this year's headphone money plus some on the BHSE amp, so new headphone purchases are a ways off.
