Amp with best bass control

In answer to your question; IME: most, but not all Krells.

When I bought my Krell 300cx I had auditioned the Sim amp as well. There are 2 reasons I went with the Krell. The speaker terminals are way too close for my liking. If you put a set of spades on them the sides would be very close to touching & it frightened me. We are talking close. 2nd reason is I believe it is on all the time. I dont mind stand-by, but on, I didn't like. No switch on the front.
The Simaudio W5 amp had great bass and sound quality when I auditioned it. It is a very good product.

Isn't Class A supposed to be superior for bass control? Wyred 4 Sound is one example.

Wyred4Sound amps are all Class D, not Class A.

Thanks all! Speakers will likely be Raidho D3's.

Krell was my first reaction, especially the evo series, but I want to hear them along with Constellation, Vitus, Jeff Rowland and a few others. I've heard (and loved Soulution), but fear the 500 monos might not have the power I need. The 700 series is out of the question, maybe the 711 stereo which is coming. But I have a thing for monos!

Thanks again!
