What to do? What to do?

My suggestion is to look for something that is relatively efficient ( 90+ db's), has an impedance that is nominally 8 ohms and leans towards the "warm" side of neutral. All of your electronics and speaker cables are on the bright / lean side of neutral in my opinion. I would HIGHLY recommend avoiding anything with a horn or metal dome tweeter as that might really compound the problem. These are only observations on my part, so PLEASE don't take them as insults to your gear. It's not meant that way at all. Sean >

For $1200 the B&W CDM-1NT. The current 600 S2 series is an improvement over what you have also.

For rock I recommend older Klipsch speakers. They are horns, but the old ones are not bright or harsh. They are incredibly efficient (LaScala's at 104db/watt). They are also incredibly dynamic, which is what you need for compressed rock recordings. What they don't do is image very well. They play very loud and tonally very accurate, but do roll off at the top and bottom ends. Their other downside is their size, so if that's an issue you might consider Klipsch Cornwalls.

By the way, these are not the greatest speakers for Jazz and Chamber. They aren't bad for Jazz, but for Chamber I don't really care for them.
