Before you start replacing cables and components, give some more thought to your speaker placement. You should try near field listening to eliminate some of the problems with the side windows. Try moving the speakers to about 6 feet from the back wall, and move them in to about 8 feet apart. Put your listening position so that it forms an equilateral triangle. This should firm up and fill-in the center image and increase the sound stage. Play with speaker toe-in and the tube traps to work the center image and sound stage. I believe that George Cardas (cables) has a speaker method that may be of benefit. Good Luck
Opinions on why this system is uninvolving
I have just upgraded my system in a number of ways from Snell Type A/IIs to Revel Studios; from Audible Illusions Modulus 2 to Hovland HP-1; and from the earliest EADs to Metronome Technology DAC and transport. I find the system uninvolving much of the time. I also find it lacking in dimensionality, find it sometimes hard sounding and I notice image wander. Here's the whole system:
Revel Studios
Hovland HP-1
MFA 200C mono amps
Metronome DAC and Transport
Shunyata Hydra on amps
Power Wedge I on other components
Various high end cords incl. Top Gun, Shunyata Mamba and EMI whales
Tara Prime (or perhaps 1800) speaker cables (bi-wiring)
Audioquest Ruby interconnects between amps and pre amp (about 30-foot run)
Hovland interconnct between DAC and preamp
Siecor optical AT&T between DAC and transport
Any thoughts on how to arrest these problems would be greatly appreciated. I was thinking about trying solid state amps like the Pass 250 or 350, the McCormack DNA line, Proceed or Rowland, but I'm not really sure that will make a sginficiant difference. I know it could change the sound signficantly, but not necessrily for the better (which I realize is completely subjective anyway).
