nfaguys, congrats on your Crown resurrection. I had a similar epiphany a few months ago with my electrostats (Martin Logan reQuest) when I moved to the 7500 (7700 sans 2 channels).

Previously, I passively bi-amped my reQuests with a Classe CAV-75 then the Outlaw 7125. The 7125 was a bit of an improvement over the CAV-75 and gave me an additional channel to boot so I sold my Classe.

Then, when it was available as part of the 7125 -> 7500 or 7700 upgrade program, I auditioned the 7500. I really hoped the 7125 and the 7500 would sound the same, especially so I could put the $500 difference towards a new sub-woofer. The 7500, however, provided a dramatic improvement and really opened up the speakers, especially in the mids and highs. I fell in love again with my reQuests. I kept the 7500 and returned the 7125.

Thank you Outlaw!

Rob
