Help need an amp for Infinity Sigmas

336 would be a good choice, very detailed and open-sounding amp. I have a classic pair of Infinity RS1b that requires bi-amping, and I use an older Levinson ML3 on the woofers, and a 333 on the mids/tweets. This has been a more than satisfactory combo.

If you move to Genesis, most of their speakers come with amplification for the woofers, and you'll need to look to tube power for the best sound from the mids/tweets. ARC VT150SE's come to mind, as would the Expensive, but excellent McIntosh MC2000. A friend has Genesis 200's, and drives the mid/tweet panels with the Mc 2000, his system sounds great!

Hope this helps!

Paul,
thanks to your response. Tube amps is a new topic for me,
but when the time comes I'll look in to it.

have you considered Classe'? A single or pair (to vertically biamp) of the CA-300, -400, -301, or -401 would be worth trying for better sound and less money than the ML's. dealer I used to frequent in Texas had everything imaginable (wilson, levinson, krell, wadia, you name it)...best sound he ever put out was the Infinity Epsilons (model up from Sigmas) run by a pair of CA400s.
