Tube integrated for B&W 805N????

VAC Avatar has the bias meter built in and the adjustments on the front panel, so biasing is easy but not automatic. Might be the best compromise to maintain great sound. Disclosure, I have a Cary SLI-80 F1 and Zu speakers and it is outstanding, but the VAC is easier to bias. Of course the Prima Luna is auto bias although I have not demo'd, so I can not comment one way or another but Upscale Audio/Kevin Deal is super to deal with. When I had B&W 805n speakers I used a hybrid Unico and it was very good. However I replaced the 805's with Tyler Acoustics Taylo monitors and it was an upgrade from the B&Ws. Good luck, everyone hears diffferently.

Wow, that is alot of good advice. Thanks guys!

Try an Audiomat - the Arpege doesn't have enough control, but a used Prelude should fit the bill just right.
