My Audiophonics S250NC stopped working properly, still under warranty. I contacted their customer service. At first they doubted that it was an amplifier problem, and asked me to ship it to them in France at my expense. Since I'm in the US, shipping cost would have been a couple of hundred dollars (for a $450 amp!!!). After several attempts, I got lucky and found someone who was qualified to look at it here in the States, and they determined that the unit was in fact broken, and also explained what the problem was. I forwarded that information to Audiophonics, they sent me a mailing label, and I sent the unit back to Audiophonics, they fixed it, and I got it back within a week. Put it back in the system this morning, and so far so good.
This is what they said the fault was:
"We have found the fault on your amplifier,
A ceramic capacitor in the Power ON circuit have been remplaced."
They honored the warranty, and I found them to be responsive, and their repair claim tracking system is first rate.
Couple of caveats:
Keep potential shipping return costs in mind when you buy products from outside the US.
It was very difficult for me to find someone locally who repairs contemporary audio products such as Class D amplifiers, so if you have a problem, your only option may be dealing with the seller who is thousands of miles away.
