Thinking of the BAT VK-55 with 2905's

The VK 55 is a very capable amp. When reviewed it spec'ed at 66 watts at clipping. I think it would drive your Quads without any problems. I use the 55 monoblocks to drive A3 Soundlabs without issue. I seldom listen above 90 db. You may be pleasantly suprised. Another option might be the 55 SE.

Does the MC2102 have a protection circuit?

So the amp turns off or something when pushed to the limits?

Regards,

While the BAT is a very nice sounding amp, IMO it does not have the power to get the most out of your quads. I am not sure what the maximum power limitation is for the 2905s, but the limitation on my 2805s is 100 watts. I run those 2805s with a Mcintosh MC 2102 and no matter how loud I play my system, I have yet to hit the protection circuits. No matter how much I increase the volume, the speakers do not take more than about 90 watts or so (those Mac meters are good for something after all).
