Any Experience with Audio Valve?


Has anyone owned, heard, or repaired Audio Valve equipment? The Challenger 160s look particularly interesting, but I can't find too much information about them. Anything to help?

David at David Lewis Audio in Philadelphia raved about them when I was browsing in his shop a few months ago. Sure he'd be worth talking to about them. He often runs big ads in Stereophile.

I own the challenger mono's they are wonderful. Plenty of power, detailed, and built like tanks
Sbank, Michael(Sufentanil) is definitely going to have something to say about Dave Serota at David Lewis Audio. Our boy Dave has the social skills of the lowest order. Wonder how he has kept from going out of business.

I have heard Michael's AudioValve setups, and have to agree the brand is definitely not getting the exposure it should. Very good sound, at what seem to be bargain prices, at least on the used market. I agree with the low noise floor, and they seem to offer an engaging sound.

One concern I have is the reliability of the product, as he has seen some issues there.
I have only heard great things as well.

But as Trelja says, there have been reports of reliability issues. I have heard OF this for their amps, but mainly for their Headphone amp, one of which I own.

Due more to shipping, but exacerbated by perhaps lesser design, there were transoformer/PC board problems. With the company in Germany, it would tough to rectify were it not for a great dealer who sold the headphone amp.

Subsequent redesign of the amp inards resulted in different placement of the transformer to alleviate the problem.

So take my commets with SOME salt grains, they ARE hearsay. My headphone amp does have the change in it, so it is fine. And as for the sound, no complaints at all ! Beautiful, clear, detailed, dynamic, open, etc etc etc.

And it LOOKS pretty neat, too :-)

Trelja,
Happy to expand offline on this, but let's just say that I'm not surprised by your comment, and that he's not "my boy", just someone who might have opinion on the question asked by Coco.
Cheers, Spencer
