Best Integrated Amplifier for B&W 685

The PM6004 is a very nice amp, and made in Japan. As far as the power goes, I've read countless times on these threads how every frickin speaker needs gobs of power to sound good. I've never found b&w bookshelves including 601 602 cm5's etc that difficult to drive, unless you are using a home theater receiver where the specs can be misleading. The Rotel RA-1062 or RA-1520 are rated at 60 watts, the Simaudio I have is "only" 50 watts, a tube amp I have is 30 watts, yet all of them drive those speakers to ear bleeding levels. Unless you are listening to them in a huge room, they'll get plenty loud without much issue, only concern would be if you were planning on upgrading later to a harder to drive speaker set.

Question for Paraneer -
I am in Japan (100V country), and moving to Singapore (220V country) soon. Want to get the PM8004 you recommend for B&W (mine will most likely be CM8).

Does the buying of step down transformer introduce noise into the sound.
Or am I better off getting the 220 V amp in Singapore.

Japan does make some of the best transformers (their power supplies are great) and the price I am getting on PM 8004 new is very good.

Thanks for any guidance.

711- The Rotel is a wonderful match the B&W's, I have listened to the combo extensively...

I agree with Mental. I used to haveB&W DM602's and CM7's and tried them with top of the line Rotel separates and It was the worst pairing I've ever heard. Very fatiguing.
