... and they affect the sound quality of your system, what affect does using Y cables to split the signal have on the system? Especially, if you aren't using high quality y cables -- do they exist?
Sorry if this is a silly question, but I've been pondering using y cables to split the L & R signals coming from my preamp so that I can feed the LFE into my subwoofer. The reason I have to try this method is that my preamp (Emotiva lmc) does not send LFE output to the subwoofer output when the speakers are set to LARGE. Setting my speakers (RT3000s) to small have a negative impact on the soundstage, imo, so that isn't a viable option for me.
