I have the Bifrost before this and plugged this into my Valhalla before my Mjolnir arrived.  Even though it uses the same D/A chip as the Bifrost, I found it to be a significant upgrade that I could even hear with the Valhalla and my Beyerdynamic DT990 (600 ohm).  If I could only choose between the Gungnir or Mjolnir for upgrading my headphone system, and my headphones didn't require the extra power, I would probably go with the Gungnir, it was a more noticeable upgrade.  The Mjolnir was noticeable but unless your gear really requires that power, it...

I'll start off by saying I prefer solid state to tube. I always found tube to be rather limiting and muddy, and I'm sure its just because I haven't listened to or owned really good tube gear. I started off my Schitt journey with the Asgard, then got the Bifrost, and then decided to try the Valhalla. I found the Asgard/Bifrost combination to be a bit dry and clinical for my tastes. I wanted something a bit (as the marketing went) red dress in a smoky room... hehe. So after some hemming and hawing and saving, I splurged for the Valhalla. I figured I...

Before getting this DAC, I ran my Asgard thru a Pacific Valve NOS DAC. I also compared this in my main home system to a Audio-GD Reference 1 DAC. When I first received it, it went into my home system for the comparison against my Audio-GD. Its not really a fair competition, but I found the Bifrost held up a lot better to rock/metal fast type of music. It was very clinical and detailed compared to my Audio-GD. I didn't find myself wanting for anything, but when I plugged in my Audio-GD I found that the music gained more life, thickness, and...

This was my first dedicated headphone amp. Before this, I ran a couple of component stereo receivers on my desk at work. I enjoy listening to my higher end home stereo system, and listening on my daily walk with my IEMs (in ear monitors) Initial impression of the chassis is very nice. It looks solid, feels solid, but can get very warm, so position it accordingly. I used it with my NOS Pacific Valve Fathom DAC, as well as straight from the computer. With a dedicated DAC, it obviously sounded better. After upgrading from my Pacific Valve NOS DAC to...
