What cables would you recommend?

I don't what your goals are, but I'd wait to see how the preamp affects the sound before comtemplating cables. As a less mature addition, I prefer a more detailed oriented, less colorful IC between the CDP and a tube Pre.

If you really made up your mind that the only thing you want to buy or try right now are speaker cables, the new Purist Audio Museaus rev. C or the Acoustic Zen Hologram II are my recommendations. The PAD Museaus is better than the Colossus rev B upon hearing both IMO and its price runs about $585 for a bi-wire 10 ft. pair. The bi-wire version really have twice the amount of wire(a true internal bi-wire) compared to the single run. On the other hand, the Hologram MK II from Acoustic Zen are much better than the Satori, the latter receive tremendous praises from owners who frequent this site. I can definitely be added to that statistics as well. These two cables(Museaus and Hologram MKII) are the best I ever tried and the only pair that stayed in my system.

...to inform, not to convince....

I'm going to take a wild guess and assume your goal is to improve the sonics of your system.

I've had excellent experience with the Pure Note Epsilon Reference XLR ic's and Audience Au24 speaker cables and 6inch jumpers.

Both are very reasonably priced when compared to the majority of cables mentioned. Yet the PN ic's and Au24 sc's have been stated by some in these parts to be better than the Valhallas.

I have not personally made that comparison, but I will say that the Au24 sc's have made the biggest sonic improvements of any ic or sc I've demo'ed or owned in my system. And by a wide margin.

-IMO

Take the bucket off your head.

Glad you remember my moniker,

Ohlala, I'm sorry. Do I know you?

BTW, killer system you have there.
