mcintosh 501's vs. mcintosh 7000?


Has anyone done a direct comparison? I know the 501's have twice the power and will have better bass control. With respect to transparency, resolution, clarity, how do they compare?

the 7000 is based on the 252, not the 402/501 architecture with quad balancing circuits.

hence, i would expect quite a big difference as the topology is so different.
I owned 7000 and i was happy with his ability to deal with detail and its treble extension. In sound regards i think the 501 is more clear. IMHO.
