In Reply to: RE: Will ARC VT50 drive Matrix 805? posted by TheBrewmaster on April 20, 2014 at 11:35:12
You usually see the power output at 8 Ohms and 4 Ohms for solid-state amps as they will often double power at 4 Ohms. This is not the case for transformer coupled tube amps.
In any case, my gut tells me that the ARC VT50 will likely work OK but those speakers can benefit from even higher power.
What amp is presently being used to drive the B&W speakers?
I've been called a Rogue Audio fanboy in the past but I'll say it again, I think the Rogue Atlas Magnum stereo amp or Cronus Magnum integrated will do a great job and deliver more power provided they are running the KT90 or the larger KT120 output tubes.
These amps put out a conservative 100wpc with the KT120s. I'm running the Cronus Magnum integrated into my larger Thiel CS2.4 with plenty of dynamics and headroom to spare. And it's a wonderful sounding amp.
The Rogue Atlas Magnum LISTS for about $1995 new.

It's for my brother, he is wanting to build his first system. He's currently just borrowing my old Carver Tfm-35x amp but wants to upgrade to a higher level system. I think the Rogue is a great idea, I'll pass the idea along to him. I'm not sure he's ready for bias adjustment though. Maybe he should stick with solid state.
Thanks a lot for your great advice.
Well, even the ARC VT50 has a couple bias adjustment pots that require very occasional tweaking while reading the setting on a Digital Multimeter (DMM).
The Rogue has a built-in top mounted meter with easy access to the adjustment pots through a removable cover plate.
If you haven't already seen the Audio Research Database (unofficial), check out the link below. Good luck to you and your brother.
