Mono Blocks on a Budget, is it possible?


I’m really struggling with the direction to take my system. I have the following:

Legacy Classics speakers
Aurender N100H media player
Schiit Freya tube pre-amp
Schiit Yggdrasil DAC
Schiit Vidar x2 (in mono block mode)

I will be replacing speakers at some point but the rest of the system I love... except the Vidars. Before them, I had NAD 356BEE that was used for the amp. Very clean and I loved it, except it was only 80 Watts. I decided to upgrade to the Vidars. They cost twice as much From a good manufacturer like Schiit so they must be better right? Not really. They are more noisy than the NAD amp and I’m finding myself less in love with them that I though I would be. I was planning the Vidar purchase for about a year and now that I got them I don’t know which direction to take in replacing them. I want to get cleaner mono amps but don’t want to spend more than $3k MAX for both. The Vidars are 400 Watts into 8ohm, are there any options out there for me that are close to the Vidar specs? I’m open to used but mostly I want the amps to sound almost completely clean with practically no distortion.

Look into Red Dragon Audio M1000 mkii. They are 550w into 8ohms and 1100 into 4ohm and go for just over $2000 apair new. I heard them being play with some Spatial Audio M4's and the sound was fabulous. I was looking to buy Spatial M4's to replace my Magnepan MMG's. The M1000's are very dynamic and had great resolution.
@mastercylinder Klaus at Odyssey runs 1.7’s I believe. Call him about spec’ing out an amp.
If getting the best possible sound within a strict budget is the priority, I don't think monoblocks are the best way to go.  Dollar for dollar, better quality will be obtained by eliminating the extra expense of monoblocks.
I second the Emotiva suggestion. It is well priced gear that performs above its class. Also very quiet. 
I also owned emotiva mono, stereo and 5 channel amps.
All I will say on that is you really do get what you pay for.
I swapped out the emotiva for the krell kav250 for stereo and the multichannel plus 2 mono s for a tiny nuforce 8 channel class d amp.
In both instances the emotiva were well outclassed.
Cheap bang for the buck but not quality bang for the buck imho
