I've had my set up of Gugnir -> Mjolnir -> LCD XC for about a week or two now.
I really loved it's sound and used it fairly consistently and ended up getting a 4 pin xlr straight through extension cable from Blue Jeans Cable so I could use it across the room, and more often.
I don't think the cable "messed up" anything because it seems to work as intended, but now when I'm using it it seems very very fatiguing at the old volume I used to listen at, which is about 8 oclock. Its seemingly grating at almost any volume. Extension cable or no extension cable. Both the Mjolnir and Gugnir I bought here and should be fairly burned in.
What do you think could be going on?
I just demoed the same combo for about 2 weeks and decided the Gungnir doesn't play nice with the LCD-XC or LCD-3 and makes for a bad pairing. At first I thought it was just the dynamic nature of the Mjolnir combined with larger volume swings that I wasn't used to, but even after taking more drastic measures than I ever had in the past such as trying with/without replaygain, using the Gungnir plugged into a variety of other amps, and trying different inputs, I couldn't make the DAC/headphone combo work for me.
FWIW, the Mjolnir with other sources or the Gungnir with other headphones was OK, but I didn't buy a Gungnir to use with my old headphones.
EDIT: Fixed typo.
