Ok...HD630VB are in da house
....not too sure what I was expecting and will obviously will need to listen more.. running off the Bryston BHA-1 and Cambridge CXN II, so far a little ho-hum....they don't really hold a candle to the AKG K872, also a closed back, which have so much more information, sounding harmonically richer, more spacious with layering and depth. Also the HD630VB with their crisper and less involving sound are completely different from the HD800s, really no family resemblance and probably an even farther departure from the HD660S which I'll compare later this evening.
A better pairing was the FiiO X3 and probably more in line with their intended purpose and where the Variable Base may serve a better purpose ....
Now these are a new an unopened box and it is quite possible the drivers may need to loosen up a tad after sitting around a few years so I'll leave them playing unattended at higher volumes for the rest of the day.....
Keep in mind I recently had unfavourable impressions on the Focal Elegia, but warmed up to them after a few days or so ....but curiosity may have killed the cat on these : ( .........
Something unrelated to the sound... the rubber for the function round, volume up/down, pause etc is very gummy so that my finger actually sticks to it..anyone with experience or has the rubber started to disintegrate somewhat like my HD800S cables????
