Best amp for Salon 2

Thanks. Also are monoblock always better than stereo all else being equal?

Really depends on a lot of things.  Better channel separation and beefier power supplies are implied, but how hard are your speakers to drive??

The reason I ask is that Anthem has 400 watts / Channel at 8 ohms. It’s hard to find monoblock with similar power without making the budget 5-7 times.

I would focus a lot more on how difficult they are to drive. If these are minimum 4 Ohm speakers then a lot of stereo amplifiers at 100 W/Ch or more will be perfectly comfortable. If they double power into 4 Ohms vs. 8 it's a pretty sturdy amplifier.

I’ve heard Revels with Parasound and ARC. Both where pretty good but also pretty laid back.

In your price range, Ayre, Luxman, D’Agostino, Pass and McIntosh are possible.  You should find a strong personal preference among them.

I own an Anthem MRX and I like it but I still use my Luxman for 2 Channel. I got to hear Mark Levinson a couple of years ago with Magico and ... meh.

Another brand you might want to listen to is Bryston. Haven’t heard them in forever.
