upgrade path from Dynaudio 52SE

I don't understand the Rotel hatred on this board. It may be mid-fi stuff but I have tried listening comparisons with Parasound, Classe, BAT, Mac and Krell - all 3-5X the cost of my Rotel gear. There was improvement but not to the tune of $8000+. I suppose I have reached a point in my life that I need to be satisfied with what I have. My room is 12' x 20' with an 80% opening on one of the 20' sides.

Stricken,
My amp is beefy enough for the 52SEs. It is 500w/8ohm and 1000w/4ohm - more than the 52SE can handle.

I have tried repostioning my sub and it helped emminsely. My room is not the best either - 12W x 20L x 8H with wood floors and is open on one side of the 20L with 2 arches. After a lengthy listen last night I really don't kow what I could do to improve - I was very pleased with results.

Yes, delayed for the most part until I can decide which path to take. I enjoy seperates but may contemplate a nice integrated - McIntosh, Classe', or Krell. I am currently reading Get Better Sound and am finding most of my problems may be the default setup I have - position of cabinet in relation to speakers, etc. My Dyns have really began to open up and am thinking, as suggested, replace the electronics. What a viscious merry-go-round this is.
