I started this with purchasing a pair of KLH Kendall speakers. After trying these out at home, I decided that they were not the significant improvement I was looking for (they are going back to the store I purchased them at) over my Wharfedales. I was gong to next try the Vandersteen 2CE's (since many people recommended them). I then acquired the ADS L1290's which blew me away (detail, presence, soundstage, dynamic range and depth are all heightened more than ever before). I may still get the Vandersteen's just to satisfy my curiosity, but this may be the end of the rabbit hole for me.
