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 very interested about your problems. Few questions:

1. First when you said it sound not ok for you, which sound property you mean? High/mid/bass? Sound stage? Transparency? Dynamic and distortions?

2. If possible you can briefly describe musical genre that you are listening to

3. What's the music that sound good? What's the music you want to hear?

4. Between, I got the Class D Audio power amp too

5. Looking at your setup, subwoofer matching here could be the problem? Maybe, bass overemphasize than high/mid frequency?

You need a bigger room. With that gear, it will be tough to get good sound in a small room with similar dimensions.

Very small room and close to being square. I would try some acoustic treatments at the 1st reflection points.
Is it possible to do an experiment? Can you take your equipment and place them in a bigger room for a couple hours? If you find you like your system in a different room, then it's not the equipment. If you don't like it again, then you need to start eliminating/changing things

Have you tried NOT using the REL subwoofer? Since it's a very small room you could be overloading the room with bass. The Prima Luna might not be the best match for your trio of speakers. A leaner/faster sounding amp(Bryston 135-Krell 400ix-Primare 30/31) and faster(better) cables(Nordost/JPS)could clean up the mid/upper bass of your speakers.

Since music sounds good at lower volume and louder sounds worse, I think it's your room.
Room treatments and setup may help.

Some people including myself (previous room) have had success setting the system up diagonally. IOW the rack between the speakers is in a corner, and behind you is the opposite corner.
Steve Deckert has a paper on it. I had similar issues, read the paper, set up diagonally and kept it that way until I moved into another room.
