New monoblocs for Maxx II, which ones

VTL S800's or get some Lamm ML2.1 SET amps... both of those should be amazing. Don't bother with the Linn or Pass.

I would recommend the Lamm M1.2 reference hybrid amps. They are 110 wpc. These have tight, quick bass response, and yet a delicate and extended treble. The mid-range is very refined and it has a nice touch of tube sound in its presentation. (They have one 6922 tube in each monoblock, so you can even do a bit of tube rolling to further enhance the sound, and it allows you to tailor the sound to your tastes. I like the Amperex Orange Globes as a good bang for the buck tube (they are around $20-30/tube), or for the ultimate in sound (& Price!), the Amperex pinched waist tubes are slightly better (albeit for a large increase in price.) The only cavaet of having the Lamm hybrid amps is that they tend to run very warm. (i.e. they will warm your room up a few degrees, but I will gladly accept that in order to get that incredible sound.)

FYI: I use the Lamm M2.1 (200 wpc) hybrid amps with my Revel Studios. I think these are the last amps I will be buying, if not forever, then for a very long time.

Good Luck in your search.

PS The DarTzeel stereo amp might be another good choice as well, since you don't need an incredible amount of power. It is a very refined solid state amp, and while I prefer my Lamms to that, there are some things that the DarTzeel does at least as well, if not slightly better. (It has incredible resolution.)

The speaker is tube friendly. So you have a wide range of amplifiers that will work with the Maxx IIs.

I have the Pass XA-160's powering theh WATT/Puppies and will never upgrade the amps...
