Help me find it again

I need your collective advice.

I have reached a critical point. If I don't start enjoying my system again, I will give up and sell!

I listen to mostly rock and pop with some blues and jazz. A little large orchestra stuff. I grew up listening to the best jazz and rock and roll live at my father's bootleg clubs. I've sat at the piano and poured drinks for the count, twisted with Chubby and lived in "Salt Pork West Virginia". I played piano and hammond organ professionally for several years working everything from rock to jazz to blues to gospel. I know how music sounds. I know how it can move you.

I have been living with my current system for about 6 months. "Maybe I'm doing it wrong, but it just don't thrill me the way that it should."

The sound is very clean but lacks emotion. It has a thin low end. Sometimes sounds harsh in the high end. The mids are good. It sounds like crap on lots of recordings that were OK on less revealing systems.

Components: Audiomeca transport and DAC, Aloia pre-amp, Goldmund 28M amps, Piega C-40 speakers, Goldmund line treatment, Piega speaker cables, Audio Techne interconnects.

I already have dedicated lines.

I'm done with vinyl. Just too much work... My turntable and record cleaner will be on the gon soon.

Room is large (32 X 20 with vaulted ceilings that rise from 10 to 18 feet). The system is on the longer wall with the shorter height. I have thick rug and window treatments. The speakers are spaced 3.5 feet from the wall and 11 feet apart. Seating is 10 feet back from the speakers and 6 feet from the back wall.

I'm thinking I need to change the preamp (perhaps tubes), but I'm willing to consider almost any changes. My current economic situation might limit my options. Also, since I live in central NC, it is almost impossible to audition anything...
