Which amp for B&W 703s

You may want to look into Classe amps. Their older line is known to pair well with B&W, and their new Delta series line is no different. I have the CA-2200 paired with 802's, and I have heard the CAP-2100 integrated paired with 803's. I actually had the 703's home for a while, and used the big Rotel 5 channel, and tried them with a Denon integrated, since I did not like the noise floor characteristics of the Rotel. The Classe CA-301 should satisfy your need for volume, although it might be a little overkill (if there is such a thing).

The Classe does look like the kind of match Im looking for. Compared to the Krell KAV-250a I was looking at the Classe would seem to be more musical and warmer. Which is what i prefer and will take an anylitical hit for that. The reviews of them mated to B&W CDM9s(similar to 703s)were favorable.
Theres alot of choice in the used Classe amp market. Now my speakers are rated at 200watts. The 200/201 and the 300/301 Classe amps are at 200 and 300 respectivly. Is over rating the speakers advisable. I was under the impression that ratings on speakers were at a given distorion for the max power. Therefore the cleaner the signal the more you could get away with over powering them. But also have to consider the peaks would be higher as well. Also under the impression that a 300 watt amp would be more dynamic as it wouldnt have to strain on producing enough power for dynamic passages(source has a dynamic range of 112db).
The cost for those amps range from $1,300 for a 200, $1,600 or $1,800 for a 201(1,800 is one with side heat sinks, later model), $1900 for a 300 and finally $2500 for a 301.
Would there be a useable diffrence between the 200 and 300 watt versions(i do listen at loud levels often)? If anyone has heard these amps id like to hear what if any diffrence in the sound was.
Once amps get a little older >5 yrs do they need new caps etc or is the life of them longer? In other words is there a point where an amp is getting a little old and one should factor in a rebuild.
Thanks.

The new Krell KAV-400xi Integrated Amp. mates very, very well with your 703s. This is one powerful Integrated Amp. with excellent sound! It has an output of 200wpc > 8ohms and 400wpc > 4ohms it will easily power your speakers and sounds great with pop, rock and jazz music. I'm using it with the Krell SACD Standard and Nautilus 804s and haven't heard as good or better for the money. You could easily pick-up a Dealer Demo. for around $2K, it retails new for only $2,500.

Thanks for all the feedback
I ended up Buying a Belles 350a. Came down tothat or running apair of Bel Cantos 200.2 in mono or the Odyssey monos. Belles seemed to provide the tight bass and still be warm for those marathon listening sessions. As best I can tell from not being able to hear all of em.

For anyone out there looking at gear...I just added a Audible Illusions L-1 pre amp. Sound with the 703s has no high harshness to it when driven loud. Smooth and powerful. Detailed and NO listener fatigue.
