What to upgrade?

Thank you for the response.

Mapman - The dynamics seem to be ok at higher volume but the highs and midrange get a bit lost with no separation of instruments. I have given subs a thought. Just not sure how placement would work and not sure how one goes about connecting them. Any ideas of a sub that would match my system?

Lak - I have also thought about room acoustics and have researched but just have no idea of what I would need. Noted below is some additional information about the speakers and amp and room:

Room
One speaker is in a corner, Back wall, side wall, cabinet, the other is open on the left side, back wall, cabinet on the right side.

Room:
There is a small echo if I raise my voice or clap.
I have moved the speakers around, Best location is about 6 ½ ft apart toed in.
Also moved them out from the wall as far as I could, about 2 ft. Interesting part is the further I moved the speaker in the corner out the bass became muddy/boomy.

Czarivey,
Thanks for your response. I have the opportunity to upgrade my components, With the room restraints I am researching all the best possibilities to upgrade gear if needed and address room acoustics for optimum performance. I listen to about 80% cdp and computer streaming. The rest with the TT.

Lowrider57 - Thanks for the information. Absorbing material or panels has crossed my mind just not sure where they should be placed.

Just for fun I used some quilts (DONT TELL MY WIFE) in areas that I thought may need a little help with reflection and dampening. I know not the greatest of material but wanted to get an idea of what this may produce in sound. It did make a noticeable improvement however it's weak in the highs, Symbols don't shine, shimmer.

ok, just a thought, The opening behind my listing position opens up to the rest of the house(I am in the upstairs loft)The back wall is about 3' high the opening is about 4' high and 15' wide. Would I benefit with some type of sound acoustics behind me?

I have been experimenting with room treatments and have notices some improvement however not as much as I would have liked. I am seriously considering subs. Does anyone have some input? thanks.
