I went to a small record store just the other day and they were selling fancy brand new turn tables that I could have bought. They also had a bluetooth module, and even a very fancy device that had 2 RCA connectors on one end, and a 3.5mm jack on the other so you could plug up something called a "phone" without even spending all the money on wireless. It's amazing how audio, for the longest time, just worked and I didn't have to think about it. When you keep things simple and standardized it pays dividends for years.
