I need to run a single pre-out from my preamplifier into two power amplifiers. The power amps have no pass-through feature so they can't be daisy-chained. Would splitting the signal from pre to power affect the quality of the signal in anyway? I really don't want to compromise on sound quality if possible. I'm thinking of something like this; http://www.cybermarket.co.uk/ishop/923/shopscr1983.html Or if anyone can recommend anything better or an alternative solution it would be a great help.
