If you can swing them high output SET like Cary 805's or and 845 based set up.I liked Bel Canto 845 amp.If you want more power and 30 isn't' enough still check out review at www.6moons.com about battery operated Class T type (much less efficient and more expensive than Class D) Redwine Signature 30 amp's.They make a 30 watt with gain control for $1500 and a pair of 70 watt Mono's for $3K.They compared them to really nice (pricey) SET.Battery operated they are supposed to have all the tonal qualities of SET but of course no tube "bloom" as they are solid state.Was only non tube unit to make the 6moons best of 2006 of 6 products chosen.Worth a read and maybe trial if you can get from Vinny the owner.
