Ozfly,
I put around 300 total feet of silver wire to replace all internal wiring for both speakers drivers and parts, deleted binding posts, deleted any connectors, tweaked crossovers/parts, speakers sit on custom made isolation boards, rings around the tweeters for imaging (this was a huge improvement!), and lastly bybee filters, which also made these speakers sound much better. Speakers cable are made by myself out of silver wire and are obviously captive into the speakers crossovers, WBT silver solders and Caig ProGold used as well.
Results?
Very good disappearing act. Voices and instruments are recreated with such a real like-life sound, very holographic and imaging is right on. Very neutral in a sense that they are not fatiguing and can be played at very insane LOUD dynamic levels without a hint of stress (stock they have no problems either). Bass is extremly controlled and very tight but not overly boomy (I think has to do with the big authority that the amp has).
Bottom line is that they definitely sound different than stock. Total sonic signature is change drastically and worth it all the way. There is alot of "hidden" sound that is not coming into the room with these speakers stock, but enough for the average audiophile, I defintely uncanned alot of resolution, dynamics, and transparency. PRAT!!!
I wanted to see how far I can take these speakers and how they would sound comparable to much more expensive speakers, well, lets say that now I am understanding what the term "snob appeal" is about now!
Thanks for your interests!
