Back to my point, I have always used Graham's PSU1, but got to wondering if that could be improved upon as the Diamond is so revealing. I found the Naim HiCap did improve on the PSU-1, and an Avondale Audio modified Naim SNAPS even more so.
Naim PSUs aren't cheap, but can be found used, and the Solo Diamond plus Naim PSU beats anything I have heard for silence and detail without any sterility to the sound. A true reference headphone setup.

unfortunately i never listen to the marvellous EAR but i had all the graham products too

the ulde is a big improvment over the Solo, the sound is mellow and neutral

deeper than the Solo and the treble more rounds
