This is so weird. I've had my main system packed in storage anticipating a move back east (from Las Vegas). After some months, I set up a "temporary" system, just to tide me over (KEF Q1 two-way monitors, Sony C15ESD CD changer, Sony STR-DA1000ES A/V receiver and B&W ASW650 subwoofer. Wire is lower-end Harmonic Technology bi-wire speaker cable and Kimber Silver Streak IC).
My big-boy system was always set-up on the short wall of my 325 sq-ft listening room which had 7 foam wall panels (from Guitar Center).
The current system is on the long wall with no treatment and it sounds tremendously good for what it is. I'm really surprised every time I listen to it. Who would have thought that just moving to a different wall would make such a difference! I think I'm in audio paradise!
