OK, the pads and shims came the other day. Although using these has made the 2000s much more stable, they are not rock solid. Interestingly, John Strohbeen has let me know that Walsh speakers, because they fire downwards, are not as sensitive to cabinet movement as conventional dynamic speakers. It does make sense, I suppose. The pads and shims did seem to improve transient attack sounds slightly. If I end up keeping the 2000s, I may experiment with some carpet spikes anyway.
BTW, over last weekend, I heard a six-figure analog system with well-known speakers that sell for over $30K/pr. I can't say if it was the speakers, room or electronics, but I don't think my modest system gives up very much to this mega-buck rig. Quite a feeling (that I chose not to share with the system's owner).
Listened to Lisa Loeb "Tails" on CD. Really beautiful overall. Again, listened to the whole CD (something I rarely did with the Vandys). I actually look forward to sitting down and listening - another new thing for me!
Starting to think that my Vandy subs are fine set right where they are. They're up in level a bit versus the Vandersteen 1Cs, but still blend seemlessly, and I enjoy the extra bass output on most things I have played. Jury still out on this one. I hope to try running the 2000s full range over the weekend. Stay tuned!
