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.

blaming a 500$ cd player is ludicrous. it is the room folks. beyond that the source is foremost."

That might be true, but its still speculation. I could argue (successfully), that the problem may lie elsewhere. Unless someone has access to the OP's system and room, we can only guess as to what the problem is. Getting good sound is a hands on activity just for that reason.
Dylanfan...Lots of great advice, and as always, Al has suggested a good idea in trying the different taps on the amp.
The consensus is that the room is the problem area in reproducing good sound, but I still say first run your system in a near-field setup to verify good synergy between components. Your CDP will sound fine playing modern CDs from quality record labels.

If you are pleased with the result, then use the full room and set up acoustic treatments. Several members on this thread have small rooms and can advise you on the size of panels.
Almarg's suggestion is excellent (I operate my speakers with a Dialogue on the 4ohm taps and get a much more linear response than when using the 8 ohm taps). You might get a lot of mileage out of using a sound pressure meter and a frequency response test disc to help you identify nulls and nodes at the listening positions (and speaker placements). This should help find the most linear sound you room can produce and the best position for your speakers. Once you do this you can fine tune using acoustic treatments which are appropriate to your problems.

But, FWIW, there are no quick fixes. Takes a lot of time an patience to get it as good as it can be.

true, but it seems a less likely problem. basically we have a very small bedroom with 8 ft ceilings. unless the room is extremely well treated its hard to imagine getting it right using a better cdp. just saying a small space like that is gon have all sorts of problems if not treated. but yo are right, we are not there.
