It sounds pretty good in the demo to me, with the mindset that it's supposed to be that modern raspy, saturated high gain sound. Really tight lows for downtuning, super aggressive hairy high end, very saturated gain level. This is the same tone so many other high gain metal amps are doing these days because it's the IN tone right now.
And yes, if you can manage to dig into some schematics, so many amps are pretty similar these days. The era of pushing boundaries as far as gain, pleasing high gain, stopped in '92 or '93ish. Now we aren't after more gain, we're after more specialized voicing taste, which is why there are so many boutique manufacturers and also so many people who say they hate X boutique maker but love Y boutique maker. They are both making nearly the same amp, but voiced slightly differently based on the designer's taste, so you either love it or hate it. It's also why I think a lot of makers are so private about their design, because it's really not that special, but they've figured out that people will pay for artificial scarcity and "vibes" or "aura" or whatever hype/buzz word sells an amp this month. (I'm not blaming them, or saying it's easy to build an amp btw, that stuff is difficult and R&D time is valuable/marketable)
This is in contrast to the "old days" where your selection of amps was much lower, and if you weren't going to have it modded (or didn't have good info on what mods to even do, there are famous mods like Jose but think about how many shitty mods there were especially before the internet), so you'd work around that core tone, maybe add some pedals or effects etc. now it's like "I didn't like the pick attack at 2238Hz, time to buy a new amp" (and I'm as much at fault for this as anyone else, I do the same thing).
*'92-93 is the time I point to because that's when we got the ENGL Savage, VHT Pittbull, Peavey 5150, Marshall 6100, Mesa Dual Rectifier, Diezel VH4, and many others still considered to be "modern" high gainers even though they are 30 years old
