Mono blocks for Revel Salon 1’s recommendation?

My Salon 2's loved my Audionet Max amps.  Used I have seen them between 13 and 18k.  They are amazing.  The Audionet Amps can be had for under 10k, but the Max is the sweet spot in their line.  The Salons love power and current.  An awesome combo.

I don’t have the mono blocks, but I second @fastfreight’s Audionet recommendation. Not the Max, but these are available right here on Audiogon:

Looking at the specs on those, it is important to note if you are using balanced connections that the input impedance is quite low for XLR. As long as the output impedance of your preamp is below 300 ohms, you will be okay. If you go unbalanced there is a lot more room to move with 37kohm input impedance. 

Nice Stereo System.  Hard to justify the word "upgrade" from those Krells.   If they are working to spec., it will be difficult to improve the sound.  Those amps were the grail for many people when they came out.  If you are bored with the sound, then, you could try tube mono amps and start a whole new phase of tinkering.   I am not sure I believe all the rave reviews of the new Class D mono amps.  If you have other reasons for making the change, ie. size, weight, heat, cost of electricity, age, etc..., then, you have many options....

Note: The way things are going, Class A looks to be going extinct in the future... If it was me, I think I would have those Krells checked out for a possible recap and bias and call it a day.  

I agree with @hjdca, the Krell KMA 160 mono amps are first class, you would have to spend $50,000 or more to best the Krells see here.
