I second the SF Power 3 amp - heard the Power 2 and 3 2 years back driving Logans (SL3 I believe) and while the Power 2 did a nice job with the stats the Power 3 did a much nicer job, at least to these ears. I have owned hybrid Acoustats previously and found that using a higher powered SS amp worked well - there seems to be a common thought that the 4 ohm load of certain stats really requires a decent level of power to make them sing. As I have not tried tube amps in the past I cannot comment on the tube vs SS comparison but IMHO regardless of which way you go I believe that you will be better served getting more power than you think you will need...
