I suggest you show some patience. The time line seems to indicate that two weeks have past since you returned the amp and in that time period the dealer has provided you with a high quality replacement amp. You purchased a complex product from an overseas manufacturer. Both of these factors can greatly increase repair times. If you're interested in long term satisfaction you should give them the time to properly fix the amp. Apparently it's not an obvious problem to address and the problem may not be easily reproduced on the test bench. What your local distributor should be doing is keeping you fully informed of what is happening with the diagnosis and repair.

Fine Sound Group, who owns ARC, Wadia, Sonus Faber, McIntosh and Sumiko also owns the Asian distributor Fine Sound Asia located in Hong Kong. You are effectively dealing with the owners of ARC.

Have your dealer demand a replacement amp be provided and let ARC deal with their problem on their timetable. Hong Kong surely understands the luxury market and I am very surprised by the level of the service offered on a $25,000 amp.

I agree. Just tell the dealer to replace the amp. Keep the loaners until the other new ARC 250 comes in. Sucks to have another 2-3 week wait for the new amp, but it's the best option. This really sounds more like a dealer behavior problem than an ARC one.

They have tested the amp for many days now and still hold the opinion that there is nothing wrong with the amp. I have told them to return the amp if they think it is good but they don't.

After much negotiation, the dealer has agreed to replace one amp and said it will be delivered in the next two days.

Let's wait and see.

Why only one amp? How do you know that the replacement amp is from the same production run? Having a pair of mono amps that do not have consecutive serial numbers may devalue resale.
