The Mjolnir wouldn't be my first choice with the HE-500. While not as bad as the HD800, the HE-500 strikes me as too forward and grainy with the Mjolnir.
I understand what you're facing.
Sometimes the infrastructure we find ourselves in, is just plain inadequate to provide us the necessary 'foundation' for really good tunes. Houses that reverberate like drum heads, power that is flakey, non-standard code electrical distribution among many other difficulties.
And especially with a lower power draw headphone system, to be hampered by power line zizz is frustrating.
I too hear small zizz when a stove element kicks on or off. Fortunately, for me, it only happens when we are cooking…
One thing to try is to replace a 'chosen' receptacle with a new one.
Sometimes duplex receptacles 'wear out' and the connections become flakey.
It’s a cheap and easy experiment to see if it is contributing to the problem, or not.
Another experiment is to use a UPS, like those used for a computer. It isn't an ideal solution for a couple of reasons, but it may just help enough.
And lastly if you have access to the main breaker panel, and are handy with a screwdriver
AND KNOW WHAT YOU'RE DOING!…
Tighten EVERY branch circuit breaker wire at the breaker in the panel.
ALL of the neutral and ground connection screws.
And let me add if you aren't familiar with what is involved with this, find someone who is… It's not worth electrocuting yourself just for some zizz…
But I'd bet between the main breaker panel wires getting tightened and a new duplex receptacle it just might 'cure' your bad case of zizz.
My Mjolnir exhibits the same symptoms. Right channel zizz, except it's a seemingly random occurrence for me.
My unit also buzzes. I have my amp on my desk, an arm's length away. The buzz is sometimes audible through open headphones during quite passages in the music. Annoying, but I've learned to live with it.
The Vali has no such issues, and neither have the other amps I've owned.
You ordered the 500 watt unit. The 250 watt unit is a chunk cheaper. Did Schiit specifically recommend the 500 watt unit?
Maybe it's placebo, but I turn down digital volume on my pc to 50%. I have to turn the dial up a bit more on the Mjolnir but the sound is a lot smoother, less "shouty", and warmer with the HE-6.
Depends on your DAC and audio files whether this is actually true. If you're sending 16-bit audio files to your DAC at 24-bit, then you're actually just losing one of those extra 8 bits of padding, not any musical data (at 50%).
Burn the heretic!
(and yes, very true that it's not bitperfect, but I still intend to always leave my DAC in 24 bit mode even though most of my music is 16 bit )
Edit: Oh, and while not bitperfect, if you're doing as mentioned above at least you aren't throwing away actual musical data, just the padding zeros.
I would assume most of you are following along with Jason as he posts up about Schiit, but if not, the latest chapter is about the Mjolnir.
