Waiting for the FedEx person to bring me 650's.
Current headphone is a 20 year old Sony MDR CD 750 Digital Reference (big around the ear closed back), which I don't think I ever cared for at all. First re-impression putting them on my head a few days ago (with lots of current runtime) was - harsh - crackly undefined sibilance - dead soundstage - honky "cupped hands" shouty sound - where's the bass - and so on.
Ears acclimated after a while and they sounded sort of "ok", but...
From all I've read here and elsewhere I have pretty high expectations for the 650's.
My stereo is up to snuff, so I have an idea of what I hope to hear.
I have a Benchmark DAC1 HDR which should drive them cleanly.
The rest of the system is:
Various digital sources - cd, oppo, TV, cable box, PC,
Sony XDR-F1HD Radio (analog outputs)
Krell KCT preamp and FPB 350mcx monoblocks
Martin Logan reQuest speakers - 14x48 electrostatic panel with 12" woofer
For occasional digital EQ a Behringer Ultracuve Pro DEQ 2496.
I don't expect the 650's to better the speaker presentation, I certainly expect them to better the Sony. If not, all you folks are simply out of your minds.
