In my opinion, Aleph 2 should sing w/p5.1 much better in the bigger room than Aleph 3. However if you would like to add more dynamic and bass authority without sacrificing too much top-end sweetness, X-250 and X-350 could be the candidates. I used to have a pair of Aleph 2 and was trying to match them up with either w/p or Genesis G-500 (w/ 500W active woofer). I ended up chose G-500 because of its build-in active woofer providing more bass authority. I was pretty enjoying Aleph 2/G-500 combo. Aleph's are absolutely outstanding amps, but just try not to match them with low efficient speakers.
