So just got the Sprout and can’t figure out how to hook up my turntable. I know that sounds ridiculous but it will make sense as I describe my issue. 
My current turntable is a cheap ION with a USB connection and the traditional analog connection (white and red plugs). I hooked up the cords and it sounded horrible. I read in the manual that you have to use an “old school” turntable without a preamp. I thought maybe I could try the USB connection but my turntable has a square “type B” plug and so does the Sprout. They don’t make type B to type B USB cables (or not that I could find anyway) so wondering what my options are.
I’ll eventually get a higher end turntable but my wife would strangle me if I got one now after just spending money on the Sprout. Is there a good “basic” turntable on the cheap without all of the bells and whistles that I can get to use with the Sprout? Thanks for your help!
