I've been thinking about these phones for the last couple of days. I've had the HD595's and 555's in the past but ended up selling them. I found the 555's too dull and the 595's too sibilant/harsh. I've always had a pair of Denon D5000's which I did love but had to sell for the money, and they were sometimes a little too sibilant.
Recently I've been looking at the D2000's as a downgraded replacement for the D5K's, but for some reason I've been looking at the 650's.
Just how different are they to the 555/595's? How is the bass/warmth compared to the D2/5ks, if anyone knows?
Or should I just save up for the D5K's again...one day...
well anyway..you may like the HD650 because they are not as "sibilant" as the D5000 but do have nice bass (but not as close to the denons in quantity). but,if you loved and got used to the denon sound signature it will take a little time to ajust to the senn sound. I know it took me some time, and even now after I got used to the sound I still prefer the denon sound signature most of the time.
I owned the HD595 in the past and although they are very nice as a starting cans, the HD650 are better by a margin.
