I have a digital PCM signal coming out of my computer to an external DAC. The DAC works fine, it's a Adcom DCA 700, but I'm thinking of adding another DAC to handle higher sampling rates. I don't want to replace the Adcom because it decodes HDCD. I'd like to run both. The computer only has the one digital output. Is it possible to spit the signal, or is there a switch of some sort available?
