Begining to look at Power amps and come across Rotels 1095 for £1600 which has 200 watts per channel and the 985 for £650 which has 110. Has anyone demo'd these amps and how much difference is there between the two? Is it worth the extra cash as I never want to upgrade the amp again. I want something that will last for 10+ years so should I be looking at 7 or eight channels instead? They will be powering Kef model 2's from a Yamaha 3090 which will be upgraded later.
