What am I doing wrong? HD 58X and a Schiit Magni 2
I am just making my first forays into hifi and headphones specifically. I use several Koss headphones and a Sony MDR-V6 through my iPhone. I don't generally don't use headphones with a computer audio source. I wanted a headphone for listening to a turntable/receiver setup and I bought the 58X to start.
I am listening to a Philips GA312 turntable>Yamaha RV303 receiver. I think the 58X are enjoyable enough at 10-15% volume when plugged directly into the receiver. I was curious about dedicated headphone amps, so I picked up a used Schiit Magni 2. Here is where my confusion begins.
When nothing is playing, the Magni 2 hums loudly in the headphone when turning the Magni volume knob. When something is playing on low volume at the receiver, the hum completely drowns out the audio. If you put the receiver up to 75-100%, the Magni volume knob is extremely sensitive, and the audio is blownout/distored sounding at the lowest audible volume.
Any advice is appreciated. What am I doing wrong here? Thanks!
