Monoblock Aegirs

I would get a pair of Vidar's, if you want monoblocks. The Aegir's are only 20 wpc at 8 ohms.
The Vandy 2's showed a minimum 5 ohm load on Stereophile, which is pretty good, but 20wpc is on the low side, especially for a 25 x 25' room.
If it were me, and I didn't need monoblocks, I would consider a Belles Aria integrated.
If I needed monoblocks, I would buy a pair of Belles Aria monoblocks.
In fact, I am have Mr. B. build a pair for my VLR's, as I write.
Belles and Vandersteen pair very nicely. Much better than Schiit, in my opinion. (And, I won't knock Schiit products.
They are very, very good. 
But, if you want something that will keep you off the upgrade train, think about Belles. PM me, if you need more info.

Thanks for the replies, you made my decision a bit more difficult. 😁 Much more to consider anyway!

This will be the best as the Class-A Aegir is for the mids and highs where it’s best at doing.

Aegir will will have plenty for the mids and highs and a Vidar great for the the bass.

Just horizontal bi-amp as I outlined.
The Sys goes on whichever amp has the higher gain in this diagram I made, it's assumed the Vidar has the higher gain, it could be the Aegir.  https://ibb.co/qjZmGsZ

Thanks, appreciate the info on the sound quality issues caused by bridging, I had never looked in to it. Using both had crossed my mind but I had always read that when bi-amping the amps should be of the same type. The sys would address the gain issues. Curious if putting the sys in-line would negate the benefits of the relayed volume in the Freya +?

They are very much the same amp, very similar circuit topology. Study the closeup photos.
Just the Aegir has much low rail voltage and higher Class-A bias than the Vidar.
