My own 2c agrees with everyone else here. Having owned them for a few years,SS and tubes work well.with some power above the 30W range definately., I actually bought mine after a demo using a Jadis Defy7 amp from a Esoteric Transport/DAC.It was the first and only time I ever heard a Vandesteen completely dissapear!( years back before the 5 came along) So, they definately are capable of responding to the best electronics, yet will sound good with mid-fi as well. The second best set up Ive heard them partnered with was a AI M3 pre into a Pair of Quicksilver Silver sixty's. Very nice indeed.But, as Bigtee points out..dont shortchange the electronics with them. What you can save $$ with the Vandy's, you can put into the front end and amps.:) Enjoy! _Ken
