Valhalla

Yes, it's pretty incredible & every review I've seen echoes my experience. The speaker cable made the biggest improvement although the interconnects are superb. My system is comprised of Wadia, ARC, Pass & Dunlavy gear.
My regular Internconnects & cables are Synergistic Res Ref
& Desingers Ref interconnects (active) & Designers Ref cable. After the audition, I'm in lust! The British mag
Hi-Fi Plus reviewed them recently.

Hope this helps

I was able to hear the difference on a modest Systeme Audio/Primare system at CES this year. The talented demo guy changed out the SPM reference for the Valhalla and everyone in the room was taken aback. These are the best cables in the industry regardless of cost and they are quite attractive, too. Check out Absolute Sound. Myles Astor gave them a "Golden Ear" award in what might have been the February issue.

I concur .They are so much better than even the vaunted SPM Reference that it is hard to believe.Pricey- but at least the cost differential gets you something-something spectacular.

Thank you all for your opinions/impressions....I have decided to give them a try.

Heard them at Stereophile show. I think the demo was fair, because the other Nordost cables demonstrated sounded familier to me. The Valhalla was a new league of sound, expansive, open, the sound flowed like nothing I had ever heard. It stomped even the Quattrofil.
