Hi this may sound stupid but here goes, I have connected my turntable through dedicated phono plug on back of my av amp, what I have found is that I always have to increase the volume after using blu-ray player, now here's the rub, is it possible to put a pre-amplifier between the dedicated phono plug on the AVamp and the turn table ? if so will it make the sound any better.
Turntable =Technics 1210 Mk2 with Grado Prestige Black 1 Cartridge
Av Amplifier =Yamaha RX-V765
Pre-Amplifier = Nad PP2
