The major difference in having the Sound Anchor stands is tilting the speaker up on the front to improve the time alignment performance of the tweeter and the drivers. I do not hear much difference in bass characteristics but do prefer having the speakers on the stands compared to without.
However, it is a bitch to move if you use the spikes for the stands... not to mention N802's are not light.
BTW, recently I hooked up a 50W/ch tube integrated amp and was amazed at the sound. Anyone out there driving their N802's with tube amp?
