I received mine (a set of 4) about a week ago. Since then I have tried them in various configurations under my SL Kraft250 amp. (not easy because it weighs 45kg), and at-least to my ears they sound best as feet for a wooden platform on top of which the kraft is located. This is perhaps the best amp. stand that I have had so far. Overall I feel that the sound has improved, I perceive wider soundstage, tighter bass and improved resolution. BTW the fit & finish quality of these are superb:clapping:. Thanks Ali!
Cheers,
Sid
