Is There any Truly "High End" Integrated Amp?



I'm a reasonably well experienced audio nut and have tried a number of "good" integrated amps. I wonder, though, if there are integrated amps that are good enough for the "best", most revealing speakers. (Think Avalon Eidolon, Verity Parsifal, various JM Lab Utopias, and a variety of other fine speakers that do not have mammoth power requirements.)

People talk about the Levinson, the Musical Fidelity KW-500 and the lesser MF amps, the BAT integrated, The Rowland Concerto, etc. etc. etc.

I would like to hear from people who have actually tried the top tier of integrated amps and would be very interested in learning of their findings.

Don't need to be the most expensive. Could be the YBA Passion, Classe, MacIntosh 6900, Krell 400i, or any of a number of integrated amps that are supposed to sound good.

Hope to hear some good feedback.

Thanks very much.

the new WAVAC has it fans though I haven't had the opp to listen to it myself
The JADIS Orchestra Reference with Kt 90 tubes putting out ~ 50 watts is really sweet. I use it to drive Quad ESL 63's and Spendor 3/5's (with Rel Stentor III) to tremendous results.
there are dozens of good ones....sugden, naim, cyrus, revox, arcam, roksan, rotel, bryston, even the creek is still a contender. you don't have to spend a lot to get alot....but if you want to spend more....arc, mac, accuphase, yada yada
Just got back from CES/Show, This year liked the RCM Bonasus integrated tube (16 watt side, $6000?) At last years show I heard the BAT being used in about half the rooms that I liked used to demo speakers etc...Was actually thinking alot about this question and it is tough. The Audion 300b SET is nice but only 7 watts and not a "true" integrated. I am currently using an Almarro a205a II only 5 watts/channel. Some of the other amps mentioned above I have heard as a demo but seems as they require carefull system matching to sound ok., well allright , all systems need to be matched but some components more of a challenge than others.
