I haven't been able to find a definitive answer to this. The problem is; I'm running a Parasound Zdac. I'm working with 1x RCA & 1x XLR outputs, both going to an amp. Now, when I get more amps, can I use a splitter to split the XLR or RCA signal, so that I'll have the RCA or XLR output going to two amps? Note: only one amp at a time will be turned on. I have been told that I shouldn't split the XLR out, even if only one amp is powered on at a time. I've also heard the same about the RCA out. I never really got an explanation on why I shouldn't do it. It honestly makes no sense to me, especially if I only use one amp at a time and keep the other ones turned off. It would be nice to get a definitive answer. If you can't do that, why not? On a totally different note, is using a 3-meter balanced headphone cable extension okay? I don't think a cable that long, of decent quality is a problem. I assume a balanced cable is just about the same as SE when it comes to this? I'm sorry if these are all silly questions, but I genuinely have no idea. Despite having been doing the audio thing for 15 years now, I've never gone too deep into how the stuff actually works. Any help would be super awesome!
