I had a Premier 17LS2 and liked it sonically (sounded much better than my previous Premier 14) but switched to an Aesthetix Calypso. My CJ had severe static electricity problems in my system. If I touched it or anything else metal in the system, the preamp muted, often with a bang (and yes I tried everything known to man to mitigate this). The Calypso does not have this problem, sounds superb, and because of its balanced inputs and outputs is more synergistic with my other components. Good luck, Dave
