Looking to bi wire my new speakers as both my amp and speakers support this. The room layout means that the first speaker is 1.5m from the amp, but the second is about 2.5m more. Is it best to run both speakers on 4m lengths or does it not make any difference over the relatively short distance? Looking at using Audio quest FLX Slip 14/4 so it's not so much about the cost as hiding 2.5m of cable slack.
