Anthem P2 or McIntosh 302 or something else

I am looking for a new amp for $5,000 or less. I am looking at an Anthem P2 or a McIntosh 302. I have Martin Logan Ascent I speakers. I have had a MC402 and a pair of MC501s before. Had to sell it when market crashed in 09. Has anybody A/Bed these two amps. Is there another amp I should consider. Salesman at store said I need 300 watts for my speakers. Any ideas/thoughts would be great. Thanks Alan
