Class A watts vs Class A/B watts

I tend to agree with Pubu57 in that it may be system dependent and you need to try for yourself.

I recently changed from a Mac MC402/C46 combo to a Luxman L590a II integrated, 30 watts Class A, and very much prefer it to the Mac combo, with my speakers. My speakers are relatively easy to drive, the Luxman drives them effortlessly, it seems much more powerful than the 30 watt rating; also, the bass is better with the Luxman.

We A/Bed the E550 and the MA7000 in the same system, the same day. There was no contest for us: the McIntosh had way more soundstaging, flow and rhythm. It made music. The E550 was dry and closed-in by comparison. It did seem more detailed but that came at a very steep cost in a variety of aspects. This was on Avalon Ascendants.

But it may well have been the E550 didn't have enough power for the Avalons, rather than it just being a lean-sounding amp. The dealer seemed to think it had plenty of power but it sure didn't sound at ease to us. Likewise, I think your speakers need more power than 30W. Amplifier headroom is key to good sound IMO and IME. Good luck.

You want everything ? Look at this:
http://www.audiogon.com/cgi-bin/cls.pl?ampstran&1283637910&/Symphonic-Line-Kraft-250-Dual-

For many audiophiles they are the last amp.

If it is in the price range, that Symphonic Line would be very sweet indeed. The longer I think about this, the more I really do get the sense the Accuphase might get pushed to hard with your speaker.

Are you going to keep the revels long term;if so I would concentrate more on proper matching of the amp to the speakers rather than the amps make .
To me it seems that the impedance drop to 2.5 ohms may make the 30 watt amp a little short of power;but I don't know the frequency of that drop.
The only way to really know if to audition the amp(s) in your enviroment.
