Hi 5imon

I'd be very surprised at 5200s sounding harsh compared to 5000s (although if your 5ks were very old with tired tweeters...) Did you change to the G61r and 5200s at the same time, or was there a period of G61r + 5000s? If you have gone straight into new speakers and new processor, I wonder if it's the brightly lit mid in the G61r rather than the 5200s?

How do your sources sound when fed directly into the 5200s rather than via the G61r? Do you still have your 506 to try 506>G61r>5200 and 506>5200 for comparative purposes?

Cheers

George
