"
What's the best choice?"
I don't know about "best" but this is what I would go with for the $$$.
2. Yamaha A-S2100 for about $ 2300
" Nos. 2 & 3 don't have DACS. Will I be able to run my TV through these?"
If your TV has left/right RCA outputs you can, or just buy a DAC and route your toslink cable to it and out to the Yamaha.
The Yamaha 2100 and Cornwall IVs should play very nice together.
