If your system has radio, then you can simply go to a place like best buy or circut city and pick up one of these \/
for about 20 bucks, although i cannot guarentee that would be the best option due to possible quality issues, possibly no tranmission through walls. But, all in all it would most likely be the cheapest way to do it.
I'm sorry i couldnt offer professional help i just wanted to offer an idea that is a possibility.
So, I've now downloaded my entire CD collection onto my iMac, which sits in the home office. Meanwhile, I have a wonderful surround stereo system in the family room (75' away), anchored by an HK AVR 325. Sadly, I have no way to take advantage of all of the iTunes features in my preferred listening location - the family room. I don't have an Airport, as I have no laptop computer at home that would take advantage of it. I don't have an iPod, either (yet). What are my options for making my iTunes Library accessible to my stereo system and how much might each option cost?
