You did not mention the size of your listening room. My Arcam A32's 100Ws are fine with the N805s on a small to medium sized room. As long as the amp can provide enough current for peaks it is fine.

The match made in heaven is B&W and Krell. I can honestly say that I have never heard the N series sound better than when Krell powers them. I have owned both and had different power amps pushing the N805 on other occasions in my home and I can't explain it but the Krell always matched up better. Who knew?.......John
Two schools of thought.First off ,tubes are great.The only way I would use tubes is to X-out bass.Somewhere around 65hz.Bryston makes a sweet xover.This system could be costly and would require subs.Don't be talked into a small sub because they are faster.Bass is bass and if you do your homework you can integrate anything with anything.I could talk your ear off on bass ! Next, solid state.Mark levenson ML-27. Bar none the best 100 watt class A monster walking the planet.Next the Krell ksa-80.REMEMBER to double sound presure you must quadruple power output.Don't scrutinize watts in the 100 to 200 watt range. The room is 22by 18.Buy a good sub. Good Luck!
Before you make your purchase, be sure to audition the McIntosh 6900 or 6500 integrated amps. I found them to be superb performers with the b&w 805 speakers. The build quality, and features, and resale value are also excellent.
Many Mac dealers will let you try one out in your home with your speakers. (absolutely a must)
By the way I had the musical fidelity A300 with the 805's. A very nice piece, and good sound. The Mac gave me better sound and better bass out of the 805's.
Hope this helps,
I had good success with Musical Fidelity's original A3cr pre and power combo, though it was driving the much cheaper B&W 602 bookshelves. The Musical Fidelity top-end is smooth and grain-free, which makes it a good match with the metal dome tweeters of B&W. The 602s can sound harsh on other amplification. Bi-amp with two if you really want to make those 805s sing. You will be surprised how much bass they can output given enough clean power. Properly driven, even small B&Ws have shattering dynamics.
PS Audio's new HCA-2 could also work well. Though rated rougly the same power, it seems to have higher peak current for driving reticent loudspeakers such as Magnepan.
