Any Suggestions?

Audience Au24 sounds like it might be a good bet. I have not heard it myself though.

I'm using a Krell amp and pre-amp too although they are not as good as yours. I have found Purist cables to work very well with Krell equipment.

I'm using a bi-wire pair of Meseaus speaker cable, but I have heard from a reliable source that the Venestus is almost as good as Dominus cables, but much cheaper. If you can get a chance to audition them, I would strongly suggest jumping at it.

I'm using two pair of Pure Note Epsilon Ref ic's (XLR versions) along with Audience Au24 speaker cables.

The Pure Notes are very good. But the Audience Au24 speaker cables pretty fantastic.

The Au24 speaker cables are somewhat amp dependent. But regardless, you should still hear a real firming up of the bass regions and lack of grain and hash in the higher regions.

Definitely worth the audition.

Some claim the Pure Note ic's to be better than Valhallas but not the PN speaker cables. Some claim the Audience Au24 speaker cables to be better than the Valhallas but not the Au24 ic's.

I've been quite content with this combo. And when one considers how much others pay for their middle-of-the-road cables and that the Pure Note ic's and Audience Au24 speaker cables don't really cost a dime more than some of these mediocre cables, it's well worth the purchase price.

Not to mention the PN's and Au24's cost thousands less than the Valhallas.
