The most important word of advise?

Research and audition speakers with your music, so your purchase is one you can live with for a long time, and make that your starting point.

I must agree with Stehno. 2 things brought my system to a level that I only read about before. I added the right power device (a regenerator) for my sources, and, I added the right (or at least closer to right) power cords. I have found that the quality or lack of quality of AC delivery to your sources and electronics is the key to feeding a higher quality signal to your speakers. Once a higher quality audio signal is sent to the speakers, and the speakers are good, then you have a more pure and beautiful sound. This is when you get the focus and individual placement of instruments in the soundstage, disappearance of the speakers, a widening and deepening of the soundstage that wraps around the speakers, greater imaging and separation, and the band playing in your room. These are concepts that I heard of for years but never experienced in my room until I experimented with plenty of power cords, and a regenerator. (already had quality ic's and sc's) If you can't do dedicated lines to help clean the ac, which was impractical for me, then a regenerator was the next best thing. And, do your due diligence with power cord auditioning until your system produces that magical illusion. There are other important issues to address. Amp-speaker matching and synergy are just as crucial.

Hifisoundguy, I agree that power quality is a big priority. I have a Purepower regenerator since a dedicated line in my family room presented a complicated install. Using shielded power cords have also helped to improve the power delivery to my system. I will likely change my outlets from the FIMs I currently have to either Wattgates or Oyaide. For me, the variables that affect the power affect what I hear from my speakers as much or more than many of the other variables and tweaks.
