New audio setup?

As stated above the Yamaha is an integrated amp, meaning it has a preamp and amp together in one box. It's not really a dedicated 2 channel amp; you would need a power amp. 

The CD and other inputs can only be used for source components such as CD, tape deck, streamer. The preamp section in the Yamaha controls these sources.

If you exchanged your integrated for a Yamaha or other power amp you could use the Freya. But then you'd still need a phono preamp (phonostage) for the TT.

Yes, that sounds like a plan. The Vidar should be able to drive your speakers no problem. And two Vidars (monoblocks) will make a very good system.

Yeah, two Vidars running balanced would provide better channel separation and higher S/N. I'll bet there would be a terrific black background.

The Vidar looks like a really nice amp (which doubles its power into 4 ohms). Sorry about the monoblock suggestion, I missed the fact that monos are only rated into 8 ohms.
