"D" amps, general discussion who's 1 and why?

I can't find what your pre is Dev.

If you'd be willing to forgo the pre, I'm thinking that you should seriously consider the Rowland Continuum 500, which gives you a great pre, power factor correction and most of the circuit of the 312, all for much less than the cost of a Capri/501 monos/PFC combination.

If you want to stay with your pre, then consider the 501s PLUS Power Factor Correction. Try to run everything balanced and see what you think. With luck you can find some used 501s here on A'gon and add PFC.

Few of us need the power of the mono Spectrons, but, if you do, there's very few substitutes right now. My experience with the Continuum shows me that huge reserves of power is a good thing, at least when the power is clean, transparent and non-punitive (as with some older SS amps in other classes).

Muralman what do you mean about "cable talk" on your system. I note that you are using cheap solutions - care to elaborate on the thought behind it all?

You can see what I am running on my system link. I will tell you this, if there is any noise or distortion in my system, it seems to be way blow the threshold of my hearing.

Jswarncke, I auditioned Cardas Golden Reference, and Jenna Labs over the same long weekend. At the time I was using Speltz Anti-Cable. The Cardas was the worst sounding of the two visitors. The Jenna less so. They both exhibit a great deal of hiss. That is the bleeding into the signal charges stored by the insulation.

On my class D system, this was an easy read.

Hearing what great results folks I know in Europe using thin ribbons insulated in Teflon, I decided to meld the two cable types, Anti-Cable and the ribbon. I knew I didn't want the insulation.

Yes, it is cheap. Try it. BTW great room!

Dcstep, pre-amp I'm currently using is a Audio Research Ref3.

What specifically is the Power Factor Correction you are referring to.

Muralman1, you said:

"Ghostrider45, I use the Quantum theory because it fits. My speaker cables are extremely thin ribbons. The music signal in all it's fruition slips through without inhibition. We are talking about the very small."

Cables are many orders of magnitude too large to directly exhibit quantum effects. You need to get into the subatomic realm for that.

I don't doubt that you're getting good results, but I believe many of us are also getting great sound through different paths. We don't need to mis-apply real science or invent pseudoscience to explain our successes (and failures).

It's all about good engineering and open minds.

Enjoy the music!
