Morrow audio makes whatever cable you need, splits, varied lengths, whatever connector you need. They have a range of cable types for every budget, often having substantial discount sales.
I’ve several of their interconnects and have found them reasonably priced and perform very well. I’d avoid the splitters and get something made to suit without spending big bucks.
apparently they’re currently moving their facility so orders are a bit delayed however.
Splitting line level out from preamp, versus using 2nd set of outputs
I'd like to add a line lever splitter between my preamp and amplifier, close to the amp end on a set of 4 meter interconnects and send signals to two amplifiers that are located near to my speakers, versus buying another 4 meter interconnect to drive the second amp from the second set of line level outputs on my preamp.
I'm considering asking the interconnect manufacturer to make me a set of female to 2 female splitters out of spare set of interconnects. I'd use two one meter pairs of the same interconnects to feed the amplifiers.
These are RCA cables.
I know that it can be done, my question is, am I setting myself up for disappointment?
