Recidivist luddite needs help please!!! I'm currently home demo-ing two Roksan Mono amps and a pre amp. I've got my B&W's bi-wired, but seem to be making a hash of connecting them correctly. 1) Do the four QED airlocks from one speaker all go into the same mono amp? And then all four airlocks from the other speaker go into the other mono amp? or 2) The four hi-frequency connections from both speakers all go into one amp and all four low frequency go into the other amp? Confused, aurally disorientated and tired. It's all The Shins' fault. Playing their track Saint Simon, I can't locate the out of tune glockenspiel sound at the end of each verse. Whereas on playback through my computer it's there in all its glory. Surely I'm doing something wrong. I seem to have tried every configuration, but have just got myself in a state. Help. I need to buy or return by Thursday.
