You can get them at Radio Shack, or if you want something more substantial, go to AudioAdvisor.com for gold ones made by Monster Cable ($20) --- I do not think they will ruin your signal, assuming the two cables coming off the splitter are not too long. I have done this on a temporary basis for a temporary setup and never had a problem.
coax Y connector
Is there any such animal as A 75 ohm digital coax "y" connector/splitter? I would like to be able to send a digital signal from my cd player to my dac and also to a cd recorder without swapping the cable each time. Im trying to avoid the toslink output on the cd as Ive always heard they are inferior to coax. Any feedback will be appreciated.
