All Legacy speakers sound best when driven with a S.S. high current amp, however tubes could be used also. I used my CJ Premier 11-A tube amp (70 watts) with great success. Sounded as good if not better than with my S.S. high current amp. If it's a good price, I personally don't think you could go wrong with the Wisper. Some would also tell you, I'm also quite often clueless, but I beg to differ...I think :-).
