Jena Labs - Any experience?

Hopper, are you on SS or tubes?

S23: I'm using the Tenor 300 tube hybrids--same as Panorama. The Jenas mate extremely well with those amps.

What level Jena cable would I have to get to compete/better the performance of a Nordost Valhalla??

Some may say the Symphony, but I'd go with the Pathfinder. You get better resolution, along with an audibly richer and more believable midrange. The Valhallas are still an excellent cable, but, in my mind, the Pathfinders are clearly better all around.

I think you might want to try and audition the Jena Labs Pathfinders. I find then more to my liking than the Valhalla.
