Nice pick. Like that they can do 4 ohm.
What type of amp are you driving them with? Low wattage? Or they need more power?
I have tried many:
Solid State:
Marrantz 1200 - Sounded good... gain @ 1/3 maxed them out
Marrantz 4300- Same as you would guess
Marrantz 2216b - Sounded decent at 1/2 gain
onkyo m-501-sounded good Gain @ 1/4...
MA- 6200 - Sounded great ... Gain @ 1/3
B&K 60wpc - Beautiful! This might be where they stay... I can get a good 2/3 gain and they react very well ...
Tube:
Ampex 6973 stereo with Carver pre - Lovely! Gain cranked
Rouge Cronus Magnum - Slightly better than good, approaching great... 1/4 gain but me thinks too much tube power... and the Canton color really seemed highlighted.
Marrantz 8b - Yummy! !!! Using a Mac pre-amp -- this would be wonderful, but the 8b is married already...
VOM 6bq5 quad - 13wpc just aint enough...
Fisher 400 - Nice but they need more...
Fisher 800b- Lovely-
HH scott 299c Lovely match but still a little thin on watts
Conclusion:
I like 60wpc SS with these...
