I've had my Arcam DV 88 and AVR100 since they first came out, had to replace the DV 88 no less than 3 times before I had a decent example - it really shook my faith in buying British. To cap it all my AVR100 is now playing up. On some DVD's (not all) when it switches over to dolby Pro Logic there is a right old pop from the amp through my poor MA Silver 8's. It also decides to switch itself off from time to time. Wondered if this was a common problem or just my big streak of bad luck again. It's not been abused and has sat quietly in the same place since I unboxed it. Obviously it's no longer under warranty, and wondered how costly this problem might be to put right ? The AVR 200 now supersedes my amp, I also wondered if mine could be upgraded to the AVR 200 for less money than buying new ?
