I recently purchased a used adcom 5503 which sounded very warm and rich only to find out the left channel was fried. I then purchased a brand new 5500 (hoping they would sound the same) and the 5500 is brighter. I have about 50 hours on the amp and I am 98% happy with it. Some very select times, the highs are harsh with the A9's I have. I want to wait until the warranty is up on the A9's before I mod the crossovers. My question is would the mod tone down the brightness of the 9's at high volume levels? Would it tone it down through all volume levels?
My general question is how do I tame the highs with these beasts?
Buying a new amp is out of question so I would like some results.
My gear can be found in my signature and I use all blue jeans cables. (LC-1 interconnects and bjc 10 speaker wire)
