Thinking about going with a seperate 5 channel amp. Looking at Emotiva UPA-5. I'm currently using an Onkyo TX-NR807 with TSI500's up front, a CS20 center and R40's in the rear.
Could I use the 5 channels of the Emotiva to bi-amp my fronts as well as power the center and then use the Onkyo to power the rears?
Would it be better to forget about bi-amping and just use the Emotiva to power all 5 of my speakers.
And lastly, would the improvements (if any) of either of the above be worth it?
