Define power hungry...B&W speakers

Your speakers call for 50 to 125 watts into 8 ohms and their nominal impedance is 8 ohms with a low of 4.6 ohms. Buy an amplifier that has 50 to 125 watts per channel into 8 ohms, and that is 4 ohm capable. Do that, and the spec sheet on your speakers will match the spec sheet on the amp. Problem solved.

Lewinskih01,
thanks for clarifying - indeed, I did misread your post! :-0

well, we do agree to disagree w.r.t. SS being better for B&W.
But I will agree with you that the huge tube power amps (like the VTLs you mentioned) will do much better than most other tube amps - but then these large tube amps are designed to supply a lot more current into a difficult load & their price reflects it.

So, assuming my speakers line up with the 700 series, how many watts minimum and what current specs would you recommend? Where do I find those current specs on an amplifier or receiver?
Thanks again!

you'll never find the current specs for most (If I may be so bold as to say "any") amp. you'll have to do the math & find that out for yourself. Make sure that the amp has plenty of current capacity for example in the 5Amp-8Amp region while ensuring that you have sufficient watts.

I had a pair of CDM 1NTs and they were a great speaker.....I used them with a 40 watt Anthem Amp 1 and also a 50 watt VTL amp. Both amps sounded great and played plenty loud. 17x15x9 room. I wish I had kept those.....

Thanks for the response. I am considering an Anthem integrated 2 hybrid. Good to know it can power my speakers.
