I agree with tomic601. The physics is real. I biwired Martin Logan Request, very resolving speakers; biwire one and not the other and moving from speaker to speaker the improved resolution (Norah Jones voice emerging more distinctly from the mix) was very apparent, even to the wife! Haha! There is a reason higher end speakers are biwireable (beyond just a gimmick to make money.) I feel sorry for the denialists, they don't know what they are missing.
Biwiring make any sense?
I am on the verge of adding new floor standers to my setup as my room has enlarged. Options being considered are KEF R7 Metas and PSAudio Aspen FR10's. Both have biwireable terminals, the KEF has a jumper switch and the PS has jumper wires to bridge the terminals. The other option from dealing with the jumpers is to biwire the speakers. In this case I could run a banana and a spade off each output terminal. Is this even worth considering? Biamping is not something I'm interested in, as I already am running off an integrated amp. I had a pair of BassZillas before, each one of which had 3 sets of terminals, the top 2 being biwired, but that's a different deal (I don't have those cables anymore). Speaker comments would be welcome too. Amp is PSAudio Spectral Strata w/150 watts into 4 ohms.
