Driving the LS6's, my experience is is having very clean power and a good amplification will make those speakers world beaters.
I had struggled a bit with mine in the highs to the point where I was blocking a few of those Neo tweeters
Oddly enough a PS Audio Power Plant Premier solved the issue and it was blissful - except that I had sold them 
Must sound great with an amp with some much dynamic range and clean power!
Congrats
Michael - Yes this amp really took the LS6's up to a new level. So much so that I sprung for a second Takachi amp and plan on doing mono blocks with biamping to the tweeter and woofer sections with very short speaker cables. If some is good and more is better, too much ought to be about right!
Hats off to Mike and the Icepower folks. They made a fantastic audio product and I couldn't be happier.
