Amps for B&W 805 Diamond: Rogue Audio or Krell, Pass labs, ML, Accuphase

Buy as new as possible- 10 years old max.  The hybrid amps (252, 352) sound excellent and do work well with the 805d.  I would avoid their entry level amplifier.   

I have owned both a Mc MA252 and currently a MA 352 in which I have used with a pair of Bowers 805S models and they seem like the perfect match in both tonality and detail. Right now for fun I’m running my MA352 with a pair of Klipsch Heresy IV’s and like the previous post above, the McIntosh is not bright and other than having a ton of headroom due the the Mc’s power, it is very satisfying and non fatiguing. 

Have to disagree with @soix here. 
The Pass Labs XA series is more refined than the X series. Let’s not confuse refined treble with softness. I’ve owned both X and XA. There is no softness in the treble region with the XA30.8. It breathes life, details and tons of air into the music. The midrange on the XA is absolutely clear with zero glare. Bass is big, deep and plush. A welcome trait for the 805D. 
At the end of the day, you can’t go wrong with either the X or XA series. Pass amps kick butt with B&Ws. 
McIntosh newest stuff should work well too. Their new integrated amps are very good.

The Accuphase would make a very nice match. Good advice above as well.

Happy Listening!

I completely defer to @audphile1 as nothing beats actual personal experience, and I stand corrected.
