Let's get this started. Share your adoration or scorn for the Gjallarhorn. Did you know there was an extra R in there? I've been in a relatively small space for awhile with my typical stack of Audia Flight FLS-1/FLS-4, and Focal Electra 1028 Be speakers. I went nuclear and upgraded to a pair of Vivid Audio Kaya 90s recently after an offer I could not refuse presented itself. I guess I don't really need to own a home. I put a Kill-A-Watt on the FLS-4 power amp and confirmed what I already knew. Despite listening at a typical 55-60dB in my space with maximum peaks of 77db, I was using a power amp that pulls a constant 285-300W from the wall regardless of load. Enter the Schiit Gjallarhorn. I bought a Bifrost 2/64 and a couple days later as I was trying to figure out how to reduce my stereo's carbon foot print Schiit announced the Gjallarhorn and Rekkr. Nice. I got two Gjallarhorns for mono-block duty. My first impressions are with the Bifrost 2/64 in NOS mode only. OS does not sound good at all to my ears. I will update in a couple weeks comparing my reference Holo Spring 3 KTE. With the right preamp, the Gjallarhorn is DEAD SILENT. This is an advertised feature that I was seeking. However, my silent preamps do not sound that great with the Gjallahorn. The Topping A90D is dead silent if I put my ear right on the tweeters. But, it sounds pretty dull and lacks soundstage depth and transparency. My Holo Bliss is too warm with the Gjallarhorn but still dead silent. My Audia Flight FLS-1 is a bit noisy but overall sounds the best so I have decided to use it here. With the low gain of the Gjallarhorn I am able to get closer to unity gain on the preamp which I feel is a good thing? The Gjallarhorn is doing just fine in my setup. The bass is full and deep, and I never feel like it is running out of power. It is not quite as tight as with my FLS-4. The mids are pretty nice, but it does lack ultimate soundstage depth and clarity when audio tracks get really complicated. The treble seems rolled off, but there is nothing fatiguing whatsoever so I would bet that's a reasonable tradeoff for most people. Each Gjallarhorn pulls 10-11W while idling according to my Kill-A-Watt. This is really what I was looking for. At "too loud" volumes in my space (75-77dB), I can see one channel reaching 12-13W. Very nice. They never get more than barely warm to the touch in my cold basement. The delayed startup results in zero scary clicks or pops through my speakers. I feel pretty safe with $600 of power amp driving my used Cadillac priced loudspeakers. The Schiit Gjallarhorn seems like it has achieved all of its design objectives. I expect to repurpose them in a home-office some time in the future but for now they are meeting all of my needs in my primary stereo.
