Summary: I bought the Caspian integrated Amp M-1 in 2005 for 1400 Euro. The sound quality was great considering it's size. For about 1.5 years it played fine but suddenly there was no more sound coming out of the left speaker. Since I was well within the warranty I took the amp back to the store where it was sent to B&T HiFivertrieb (which is Roksans importer in Germany). After 4 weeks I had it back.
