Curious ... and clearly noting that Stadium is still in its embryonic stage .....
.... been reading this discussion and stuff at TOP .... Agoura seems to be considered fantastic for clean , e.o.b, crunch , rock tones .... but quite a few people seem to be saying that the higher gain / very high gain amps are "not quite right" yet in Agoura (?)
Is this a "fair" / "accurate" representation of where things are at currently with 1.2.1 (?)
I come at it from a different perspective.
First, your synopsis of the chatter seems about right. That's what people are saying if you boil it all down to a condensed version.
I have no idea to what extent the universe of comments is objectively accurate.
I come from never having had a room full of amps I've logged hundreds of hours messing with. Being an ignoramus in that regard leaves me in a position to have to decide between "sounds good to me" versus "doesn't sound good to me" with the basis being some amorphous blend of memories of groups of tones I've absorbed over time. It's interesting to me to read all the comments from studio operators and producers and high gain amp aficionados, but I have no basis for making such judgements myself.
With those caveats, I get tones that range from clean through "hard rock tones" 70s/80s style that I enjoy and sometimes find glorious. That's in isolation--I'm not trying to exactly replicate any particular guitarists tone from a particular past recording. As far as the modern high gain stuff, I've never really developed much of an ear for it. When I listen to "shootouts" people post online comparing different modelers and/or discrete amps I generally like them all. Sometimes I can hear distinct differences, but 90% of the time it's just different, not a case of one being great and another being bad/wrong.
I find myself wishing Line 6 would address this. I think there's enough material out there illustrating differences in some cases that, if you're going to stake your approach to be one of accurate modeling of the hardware, warts and all, and even build in a feature (Hype parameter) to smooth over those warts and make the sound more studio polished if desired, then for people that type of accuracy is important to, some indication that their concerns are warranted (or not) and indication of the existence of a path forward if appropriate, seems fair. For users like me who just want a device that fills the role of an amp in a signal chain and get a more than "good enough for government work" replication of a breadth of amp tones, Stadium appears on a path to meet that need in spades.
We'll see what the future of Stadium brings, but I'd have to say to someone considering Stadium mostly for high gain amps with lots of abrasive sizzle generated in the amp models just like [some favorite high gain tube amp(s)], try before you buy or maybe consider waiting to see if/how it all settles out. Unless my musical tastes and playing goals change someday, I have essentially no complaints about the Agoura models.
