I am the process (in the sense that I would like to begin making purchases) of building a new stereo system. For the time-being, I am using an Aragon amplifier with an Emotiva XDA-2 as dac/pre. They are connected by rca. In this configuration, I have no buzz issues. However, when I replace the Emotiva with an Aragon a/v pre, I get a low level buzz (it sounds like a 60 hz buzz based on listening to a sound file of same). The Emotiva inlet is 2 prong; both Aragons use a three prong.
In an effort to resolve the problem, before buying anything I have tried the following, all with no result: Jensen Line Input Isolator Hum Eliminator; Ebtech Hum X; use of a UPS; connecting the chassis to the ground connection on the back of a Panamax line conditioner; unplugging the cable boxes elsewhere in the house and disconnecting the cable line that outputs from the Fios ONT. I have also changed cables and power cords.
I have tried to isolate the issue as well. The room with my equipment is in the basement and has its own circuit. With all other power off in the house, the buzz remains. Similarly, after renovating my kitchen (the buzz predates this work), a new circuit was installed. With all power off and the equipment plugged into this circuit, the buzz remains. The outlets have been confirmed to be wired properly.
I am likely to look for equipment that allows for balanced connection but I had hoped to eliminate the buzz before buying anything. If need be, I could live with the buzz that is not audible from my sitting position and is unaffected by changes in volume. My concern is that in the move from bookshelf speakers to floorstanders (likely Revel f208) that the buzz will be louder due to the additional drivers. As a general matter, I would obviously prefer to not have this buzz at all.
Any help is appreciated.
