I owned that Spendor about 15 years ago. I now own the Harbeth SHL5 Plus. The Spendors were nice but not in the same class as the Harbeths. If you want to do a fair comparison the Spendor classic 1/2 would be more realistic. Both are 3 way stand mounts.
BTW, I have owned many Spendors and Harbeths and the 5 is my end game!
