1. Is there a big difference in the quality of low budget EQ's? 2. Even if it is not needed, is it a good idea to incorporate one if one is available? 3. Anyone here have a technics model SH-GE50? And if so, are you happy with it? I have one, and am about to incorporate a Kenwood VR-507 reciever into my system using my old reciever as a sub amp for my DVC Cerwin Vega sub. So hopefully, I can make good use of the EQ. Thanks in advance for your input.
