My Pioneer LX72 amp wouldn't turn on one evening and the power button just showed the constant blue light with an error in the display which when referenced back to the manual described the unit as needing a repair and beyond a 'user fix'. I did the usual power offs over a period of time, hard resets etc. Same result. So I called Richer sounds and they said they could get it looked at for an initial cost of £65. RS then send the unit off to ServiceCare and I wait for confirmation that it can/cannot be repaired. So i drop the unit off into RS. 4 weeks had gone by and I had not heard anything from RicherSounds, so I called them on several occasions to get an update - with mixed results. Transpires that ServiceCare were waiting for my authorisation to proceed with the repair at an additional £38. I approved there and then and was assured the amp would be swiftly fixed and returned to me. Onto week 6 and last week I had to chase RS to see when I could expect the amp back. Much to-ing and fro-ing by RS with ServiceCare and they are now saying the part was ordered, is on back order with no date therefore amp being returned and not repaired. I still await a call to say my amp is ready to collect. I have asked RS to get the fault diagnosis and I can understand the part that has failed. My question to you guys is who else reputable can I try for a repair and is it worth trying again IF I can get details of the part to be replaced? The amp was £1600 in 2010 and while old is still as new condition and suits my setup perfectly. It's not going to be cheap to replace. If it is not worth the further repair hassle, what amp do people recommend that will suit (and drive) 3 x B&W CWM (In-Wall) LCR7's , 2 B&W CCM80's (In-Ceiling) and 1 x BK Electronics XXLS400?
