Hi

My own experience is that you will hear an improvement. These are such great amps, moving from one bi-wired to 2 in mono mode made a massive difference to SQ for me.

I have read elsewhere on here that 2 running bi amped opposed to mono sounds even better.

A friendly dealer should be able to lend you a pair of speaker cables to compare before purchasing. Chord speaker cables are so popular amongst dealers (mine has loads of pairs, rumour, rumour 4, odyssey etc) and I would imagine you could try with any of these to experiment.

Good Luck.
