Thanks for the comments boys.
Yes the denon 3805 is a 7.1 CH Home Theater A/V Surround Receiver:
I´ve added an Emotiva UPA 2 using the pre outs on the denon.
the difference is excellent! the sound is very clear and exciting!?!
Hence the questions:
1) If I add a further 2 ch. amp (which I have sitting on a shelf collecting dust!!) to the denon, using the pre out marked centre, would this bring a bit more life to this speaker,
and
2) how would a stereo amp work one speaker. (it can be bi wired).
many thanks,
M.
