Are my Yamaha AVR (RX-A2060) and Monolith Amp (3x200) mismatched?\n\nI added a Monolith 3x200 Amplifier to my living room setup few months. To be honest, I didn't see any huge improvement in volume at the least. I had lots of issues with ground loop hum. I ended up moving my CC speaker back to the AVR and hooked my L\/R speaker through a passive hum eliminator. With this I was able to eliminate the hum issue but the performance issue remains\n\nMy current Setup - Yamaha RX-A2060 -> L\/R PreOut -> Hum eliminator -> Monolith 3x200 Amplifier -> KEF Q900\n\nWhile doing some research I stumbled upon couple of threads discussing inadequate Peamp voltage output from Yamaha AVRs\n\nHere is a statement from a Parasound engineer to a customer that I found in a post on Emotiva Lounge.\n\n"Yamaha has been problematic with external amps for years, because they have unusually low output voltage. At full volume you will get less than half of the rated power from the Parasound, This is not an unusual for any external power amp, and the Parasound fully complies with THX recommendations for sensitivity. You should consider a different receiver\/preamp brand than Yamaha. Yamaha has kind of painted themselves into a corner"\n\nMonolith Amp specs state that it needs 1.6 V to put out its full power output and has a Voltage gain of 28dB\nYamaha Specs - Rated Output Level - PRE OUT - 1.0V\/470 Ohm | Maximum Output Level PRE OUT\/ZONE OUT - 2.0 V or more\n\nI am confused whether my AVR is not giving enough voltage to Amp to show me improvement or am I just looking for issues when there is none and just had too high expectations when it came to impact of adding a separate amplifier to my setup. Now I understand that the passive hub eliminator could impact the signal and I planning to do some measurements with and without it in the circuit but even before I added it, I was underwhelmed with the performance.\n\nNo one knows more about these issues than @gene and I was hoping if he can chime in.
