So this has been a trip but after nearly a week I think I can have a take on this.
First off, build quality is great. From Kharkiv, Ukraine, a city in part known its tank factory, this thing looks like its built there. Its surprisingly not as heavy as I thought, but it's nonetheless a solid, minimalist industrial piece of kit. The Back in Black paintjob is nice, has a bit of metallic flake in it and fits well on my desk. Do I regret not getting the sexy green? Eh, not really. It's big, that it blends is probably a good thing.
Knob feels good and weighty, pot is smoother than anything I own but there's a slight scratchiness to it which you dont notice it in the actual sound. Its satisfying to roll. Pre-out switch is a bit stiff and honestly would have preferred something else for switches if I *have* to nitpick but it all does the job just fine and for a minimalist build it works.
As for sound, this thing needs burn in. It craves it. It's straight up not good out the box. Let it settle. At first I thought it was harsh and had typed out some thoughts finding it had an uncomfortable tone on the highs to the point of being a no go for longer listening sessions. The bass was stronger than my tube amp but it was ultimately sounding like a poor-man's version of my Schiit Valhalla where it just wasn't doing anything better or meaningfully different. Buyers remorse set in. 24 hours later it was a total 180 and having given it the weekend to just play with and enjoy I can confidently say everything I hated about it is gone.
This is a tubey sounding amp. It's warm, it's buttery, it has powerful bass and smooth highs. The bass can be a bit blown out at times with my current EQ settings (which I'm trying not to change so I can A/B test a bit at the moment), and its a bit deep but without definition. Without my EQs going if I had to pick I think this is the best 'stock' amp I have right now. On the whole playing with this has had me listening to and rediscovering music like I just bought the weirdest set of vintage tubes. I mean really, this thing is not natural or neutral, it's *very* flavored, it makes my Valhalla (with 50s Brimar tubes) sound neutral.
Percussive drums & guitars cut through bass like a machine gun into a mountain of Jell-O. It's a flavor, it's not neutral, but it's ultra satisfying. Longer listening sessions are very nice. Put on some heavy metal and the smoothness means I can crank the volume higher without blowing my ears out (see: volume scaling below) or put on some electronic music to zone out to and let the bass and rich lower tones wash me away.
Volume scales nicely with this mix, and I find myself using high gain on older (pre loudness war) tracks, and it plays nice on recordings with deep dynamic range. The whole "use high gain for planars and low for Sennheisers" or whatever lines I hear from some reviews is nonsense. Low gain is too low to listen to on my 300ohm headphones for a lot of tracks, so I'm usually on medium the majority of the time.
**Anyway, enough rambling. Amp good. Amp smooth. Fake super tube in metal box from tank town.**
