ARCAM compared to Krell

Which Krell models were you looking at, and what are you trying to accomplish?

Krell is MUCH more expensive gear than Arcam generally, though there is some overlap between Arcam's high end and Krell's entry level stuff. Arcam gives great sonic/video value for dollar. Only you - through personal auditions - can decide if Krell offers you enough more to justify the price. Don't let any salesperson psych you out by bad mouthing your Arcam stuff as "mid-fi" or any such nonsense. For most people in most circumstances, it is great equipment.

The P7 is just 125 watts per channel. I am thinking of buying the B&W 802's and the 125 watts will not be ablw to drive them. I totally love the ARCAM stuff the musice is extraordinay and very worm, even the krell monoblocks cant give this much wormth. But my onl problem is power. The dimentions of ARCAM are also perfect.

I don't think I would assume your Arcam gear won't drive the B&W's just fine. I know B&W's by reputation do their best with gobs and gobs of power driving them, but you may be very happy with the sound out of them with your Arcam.

When I first got back into the hobby I had an Arcam A-65 (40 watts). One dealer told me he would normally never recommend trying to drive B&W's with something that had only 40 watts, but because of the quality and stability of Arcam's poweramp output, he thought I shouldn't hesitate to give it a try. The problem is that you need an amp that can keep pace the B&W low ohm dip (around 2 ohms I believe) which can really tax lesser amps. I suspect your Arcam is up to this. I am not saying that more high quality power wouldn't be ideal, it just may not be necessary.
