Thanks for sharing. I am a soon-to-be-owner of a set of Sierra 2's. I currently own a set of Piano Black Sierra 1's and have been enjoying them for approx 6 years now. The bass in my room is very good with the 1's. I'm expecting the bass quality to be different when I receive the 2's in ways described here on this forum many times.

Mag_Neato, you mentioned you paid for upgrades for your ADCOM and you're very happy with the results. I am running my Sierra 1's with a Harmon Kardon 3490 stereo receiver. There's a guy on-line who works on HK receivers in a similar manner. His site and services grabbed my attention but I never sent my HK in to him because I was skeptical the results would've been noticeable. But your positive experience has me reconsidering!
