Amp with Revel Ultima Studio or Salon

I use the ML#436 amps with my Salons and this is a great combo. I also used these amps with a pair of Studios for a couple of months. I've also auditioned the Bryston 4bst, the Classe Cam 350, and the latest Krell 450 monoblocks. To me the #436' were the most musicale. These amps were built wtih the Studios and Salons in mind, and really fill out the bass while being very dynamic and transparent. The amps image incredibly and each intstrument or voice is a treat to listen to. They have never given me listener fatigue even after several hour, but I don't listen to the amps at extreme or near clipping levels. I believe a pair of 436s will more than do the job on your Studios and provide you with plenty of headroom. I'm actually biamping my Salons with two pair of 436's and audiophiles who have heard the setup are really amazed at how musicale and accurate the system is.
I think the Bryston 7B would be a good choice as far as driving the speakers to loud volumes, but if you want a more musicale experinece go for the 436's.
Also keep in mind that your speakers were designed long after the Levinson amps you mentioned, so they were designed for the 334, 335, 336 and 400 families and of course the 33's and 33H's.
Hope this helps,

Bryston would be a grand Blue-Collar solution for either the Ultima Studio or Salon. As the as the older 7B-St's are a STEAL compared to the 14B-ST, 14B-SST, & 7B-SST. The Pass X600's, & Sim Audio W-10's would also liven them up if your Budget can stretch? Anything in the SS wpc range of 350, & greater will show of their true potential. I did not care for the Cooling Fan Feature in the newer line of ML 436. IMO it reminds me too much of a Mid-Fi A/V Receiver. Compared to the older 300 series sound quality it's like Mark wasn't even in the loop as far as design. Maybe he was just spending too much time at book signings of his book The Ultimate Orgas... to even care? Good Luck, & let your own ears be the final determinating factor!

It is my understanding that with proper set up and ventilation, ML 436s have to work pretty hard before the cooling fans are thermostatically signaled to operate at all. 436 owners out there, isn't this the case?

I use Thor's 60 watt tubed monoblocks with my Studios. Amazing sound, definitely among the best amps made. Wonderful build quality. I used to have a large SS amp, which was very good, but if you really, really want to take a step up, take a look at Thor.

I think the Revels are voiced with Mark Levinson electronics.
Someone correct me if I am wrong.
