My stereo isn't doing it for me. Need advice


I have been trying to get a great sounding room for a while now and it still doesn't sound great or even good. I have a Prinaluna Dialogue 5 power amp and a Primaluna Prologue preamp. All with stock tubes so far. A Marantz c6005 CD player. Morrow mc3 interconnects and Kimber 8tc speaker cable. My speakers are Dynaudio x12's which sound the best in my room. I also have Dynaudio x32 speakers and a pair of KEF LS50 speakers. Also a REL T-5 subwoofer. My room is my office and is 9 x 11 with 8 Foot ceilings. Some acoustic stuff sounds great but the louder stuff not so much. I find I listen to music that sounds good rather than music I want to hear. Any suggestions on what I can change. I also bought a Class D Audio 200 watt per channel amplifier that makes everything sound even worse.

I'm not an electrician, but I thought you had to have 2 legs in order for your AC to work properly. I had one leg go out in my house a few months ago and nothing worked. It was a nightmare. Maybe we're not talking about the same thing?
a hindu sage was confronted by a man who said his meager budget forced him to live above a noisy garage and he had trouble meditating, the sage asked his students to submit a solution. they all got it wrong. finally the sage said to the man in question....MOVE.
I read the Decware paper linked above by Sebrof and myriad of other "how to" articles and am still lost. I already had Room Tune products in recommended ceiling and corner spots. But when I added acoustic panels at first and second reflection points and behind my listening position, my sound became lifeless and boring. IMHO I over treated my room. But did I? I thought I treated the room correctly. Is it just a matter of getting used to the new sound?
And for a room with an 8' ceiling are 2'x4' panels to be placed midway on the wall or on the lower half or upper half of the wall? I apologize for such basic questions.
Another thing to try is to put the speaker into the corner, right against the wall.
