Hello Vintage Audio Enthusiasts,\n\nI have an Onkyo TX-3000 vintage receiver and a new Insignia STR514 receiver. When I connected a vintage Technics SL-3300 turntable to the vintage Onkyo, the sound was great. Unfortunately, I am selling the Technics turntable, but I have two other vintage turntables I would like to connect to the Insignia. Can I hook up a pre-amp to the Insignia in order to play a vintage turntable? The Insignia also plays Bluetooth (but low volume). Perhaps, there is a BlueTooth solution\/add-on for the old Onkyo? I listened to the Smithsonian Jazz Collection 9-record (1976) set the other day and I'm hooked on Coltrane and Sarah Vaughn.
