Check out www.amphony.com. They have something that might work for you. I've considering a similar project myself. Let me know if it works out.
Does this product even exist???
Hello, here is a question for you digital/computer type guys. I would like to know if there is a product out there that would let me transmit a wireless Digital audio signal to a receiver beside my Audio system that will output into my CD Player's Digital inputs. The reason I ask is because I have lots of very high quality MP3's that I'd like to listen to through my DAC. I would like to avoid having a computer sitting beside the system as it introduces high amounts of EMI and fan buzzing noises. Any other creative solutions would be welcome. The DAC accepts all types of Digital inputs.
