should I go with the rega brio or schiit vidar

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. 

Thanks for the responses and suggestions. It sounds like the best option might be the schiit vadar.
The nuforce sta 200 is interesting. Would this be similar to the performance of two  nuforce ha -200  amps.
How would i know if I can use my Oppo as a line stage. I'm not sure what that means, sorry I'm still new to this.
Last, since the rega is also a preamp will this sound better than just using the oppo as a pre amp

Thanks again for all the feed back it is a big help.

Looks like you can use the Oppo's volume controlled output to connect directly to an amp.

From the Oppo site:
"Sonica DAC provides both XLR balanced and RCA single-ended outputs, and the outputs can be set to volume-controlled or bypass, making it suitable for connecting to either pre-amps or power amplifiers."
