I've had my Yamaha A-S501 just over 4 years now and I'm getting the upgrade bug (no known cure) again. I originally thought about upgrading to the Cambridge Audio CXA80 and CXC, as it's now being discounted. However as the matching network player is still a bit pricey, it's a quite a bit over my budget and grounds for divorce. A more wife friendly option is the Marantz PM, CD and NA6006 series. The only thing that bothers me is the low power output of the PM6006 when compared to the A-S501. This may or may not be a bad thing as my listening room is just over 3 metres square, plus the Marantz amp is said to be mellow sounding according to some reviews. Any ideas, should I pull the trigger?
