I tried the lower priced series first and heard improvements in almost all areas of the music, decided to go for the higher priced spread. The 2 series really made a difference, especially the power amplifier modules. The most notable difference in a/b tests is in the bass and image. However, the longer you listen to these things the more you realize how much more "musical" the sound is. Which is what we are all looking for, right?
I tried individual units on my second system and it didn't make as much of an improvement until I had "conditioned" everything, cd player, preamp and amp.
The do it yourself tweeks at their website are very interesting. I used the vibration isolators on my system and it really tightend the sound up. I have a pier and beam floor in my listening room which has always been a problem. The isolators under the subwoofers really helped.
