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

@soix 👍 

Something else to add…

One downside with Pass labs gear, if you can consider it so, is the fact that it takes about an hour minimum for their components to warm up and perform at their peak. It isn’t exclusive to pass however in the case of XA with pure Class A operation you’re looking at 380w power consumption at idle. I never measured how much the XA30.8 amp actually pulls from the wall during normal listening but I’m pretty sure it isn’t shy. If that’s a concern then opt for Class A/B X series. Slightly more efficient. As far as heat, the XA gets warm but won’t be a space heater. It’s more than tolerable. Hope this additional information helps as well. 
 

@audphile1 If it takes 1 hour to warm up a class A Pass Lab amplifier so it will be a problem for many persons. This issue only happens with Pass or for any other class A of other brands?

@buckheadmac Yeah, I know the MA252 is very good but it is only 100W. Is it enough for 805 Diamond? Normally I see people use 150W or more amplifier?

@jafant which one would u suggest. E530, E550, etc..? I know that Accuphase sound very good but I'm only afraid that Accuphase is hard to bring the liveliness and joyful of the song to us

Audition several Accuphase models as possible.

Stay in the 50 Series, 550 or 650. Believe me a Joyful song will be appreciated and enjoyed.  Keep me posted on your demo sessions.

Happy Listening!

@truongv0ky it’s pretty common for any component to take some time to start sounding its best after it’s on and out of standby. It will sound just fine when it’s cold but will get even better after about an hour is what I’m saying. It isn’t proprietary to Pass Labs gear and I wouldn’t classify this as a problem. 

Thx all you guys for very supportive advise
