should I go with the rega brio or schiit vidar

If it were me, I'd go with the Vidar and see how it pairs with your Sonica. If you feel its too dry/clinical, you can always add a tube preamp or even a Freya later to add some warmth and juice up the soundstage and still stay under your budget.  

i would get 2 vidars if you have balanced outputs. 400 watts into 8ohms

All good ideas. Consider also the used Hegel h80s which are going for very good prices now. They have balanced ins which sounds great. 

The Vidar’s balanced input numbers exactly one, so if stereo balanced connection is important you have to buy 2 Vidars.

Not to hijack your thread, but I've been looking at a lot of Schiit lately. Egads, doesn't this ever get old?

Looking to replace my amplification, a Kenwood Integrated from college days bought in 1978, really. Served me very well for all that time.

Anyway, I have Energy Reference Connoisseur 22s.

Has anyone heard the Shiits, Vidar & Freya?

Cary has a sale ending in a few days that's compelling, to me. SL-100 Pre $1,197. and 200.2 Amp $2,397.

The Rogue separates are more than what I'm willing to spend.
