I wonder if anyone can help. I have a Yamaha AV receiver which being quite a recent model needs a phono preamp when connecting a turntable to it. The turntable that I have - the Bush MTT1 - has a built-in preamp with on/off switch. When that is switched on the TT plays OK through the receiver. However, the volume is only about half that of my other sources ie the DVD, CD, minidisc and tuner. I thought that a preamp is supposed to boost the volume level up to that of the CD and DVD etc. If I added a standalone phono preamp to my system (with the TT's preamp switched off) would it increase vinyl playback volume to the level of the CD and DVD etc?
