It wouldn't be CES without a few turntable announcements, and Sony is unveiling a new model of its own this week. The PS-LX310BT is a wireless turntable with Bluetooth connectivity for playing your vinyl collection over wireless speakers. Don't worry, purists: You can still connect it to a stereo system with wires if you want to. This new turntable features a gain select switch that will allow you to choose between low, mid and high -- whichever setting best suits the audio level of the record you're playing. Basically, this should relieve any headaches when you go from a quieter LP to a louder single.
