I have put the Karan I-180 (the newest version) into my system, running it against the ARC LS26 and SD135 combo on loan from a dealer, as well as my McCormack DNA-125 Gold and Dehavilland preamp combo. I picked it up for a demo based solely on recommendations from people I trust, which is probably how most people find out about them. This is definitely an integrated that you should check out. The Karan was both more detailed (I am hearing tons of things in the music that were never there before)and more "tubey/musical" sounding than either of the solid state amp-tube preamp combos. The McCormack and Dehavilland were bettered slightly by the ARC combo (more detail, sound is a little less lush and more accurate) but the Karan goes way beyond either of these: it has better control of the speakers, more accurate bass, more natural, and really shows off good recordings vs. mediocre ones. I have had some pretty nice separates in here for demo recently (Herron separates, Classe CP-700 mated with the McCormack) and they each beat my setup by a small margin, but the Karan is in a whole different league. They are tough to find though. Now, I just need to get my wife to let me keep it.....
