I really don't know what the problem is here, but something doesn't sound right about this whole situation. Maybe the business is in some type of trouble. Its possible they may not have the resources available (parts, labour or both), to fix the amp. If it were me, I would do whatever I had to do to just get the amp back. I would rather pay someone else to fix it rather than watch the manufacturer close down, or something, and loose the whole thing.
Manufacturer Repairs? What is a reasonable time?
I sent a solid state amp back to the manufacturer in the USA on March 16 for a minor repair - one channel input not working - despite 4 phone calls and 4 e-mails - he hasn't even started the repair. Doesn't respond to emails but does answer the phone and says he is busy and is alone. I Will not identify him yet, since I'm not sure what the "norm" is, since I have always been thoroughly spoiled by Bel Canto, Atmasphere, CJ, AR, acoustic Zen, Cambridge, EAR, who respond immediately and usually have my unit back in 2 weeks. So when do I start to play "ugly", realizing that the economy is bad and manufacturers may be struggling?
