Ah - I was thinking of having two sets of amps/speakers (or DSPs) just to try out a second set of power cords!

That does explain it!

Certainly I agree with one of the things - although I know what at transformer is I have no idea what a torroidal transformer is, I do know however that the one in my "little biddy" Krell weighs a ton and for the most part, all of the weight of the amp. I always figured that an amp would soak as much as it could into massive capacitors and leak current as and when required through the op amps. The faster these capacitors could achieve full charge (more expensive, larger capacitors) the better - so if you could get more current into them quicker, you would have a more even response when pushed. This could be complete hogwash, but the physics sounds good to me at least!

I'm no posting any more on here until I have heard one of these wee beasties.
