Yeah, I’m coming at it from a different angle. Couple of reasons I'm trying these things out:
(1). curious/bored
(2). like a lot of folks that love digital, I also still occasionally feel like I get lost in the weeds. By this I mean one of two things (which I will of course label "a" and "b" instead of "1" and "2"):
(a). Feeling like I don't quite have a grounded "home base" reference point. A firmware update pops up, changes the cab block and everything is all of a sudden a little different. A new amp model or two are added, you go off exploring, which then sends you exploring a few other amp models you forgot about, in Fractal land the Gravitational Force Vector Constant is updated to better reflect NASA's most recent measurements, the variable compression contraction expansion power transformer modeling is updated and, oh, yeah, we realized we accidentally had a 500k pot in that one spot that should have been a 10k pot so we updated that. With perfect preset management, and rolling back firmware, etc., but even with that there's just some inherent distrust that everything is "back to the way it was" or whatever. Would be nice to have one rig/setup/system that I can easily plug into and say "alright, this is tone central. It might not be the Ultimately Optimized tone or rig, but it it was one that is good, that I know, and that is immovable."
(b). Missing the "feel" of plugging into an amp-and-pedal rig. I'm not talking about some magical compression that you can sense under the fingers but not hear, but just the overall emotional and physical experience of plugging into a rig with one-to-one knob - to function and on/off button correspondence that requires no programming aside from rearranging patch cables. I love digital and for the most part have no problem plugging into what amounts to a computer with a terrible user interface, but like any self-respecting Gen X-er, I still miss the good ol' days of pedals and amps (even if they were all solid-state) and a Friday night trip to Blockbuster (okay, I don't miss that at all).
The power amp side for me -- as we've spoken before, I haven't had great experiences with attenuators. Tonally I didn't like it, and I also hated the anti-goldilocks "this click is too loud, but that click is too quiet" conundrum. Lower wattage amps sound great and impart plenty of compression even at home volume, but I hate the fact that you are almost always in a different part of the headroom curve so your pedals/reverb/etc., are always reacting/sounding different which drives me nuts. So...master volume amp, or some sort of load/reamp scenario where the load probably doesn't reflect that kind of cab that would be used in conjunction with the kind of amps I like? Once you're in that area, I feel like the quibbles over "but the preamp and power amp aren't united into a single orgasmic body with shared power supply that causes each to sag in concert with one another at a matched impedance level that God Intended!" are kinda moot.
I think we all get a little too wrapped up in the "does it sound like a REAL amp?!?" discussion...at the end of the day, I will never have something that sounds like "the real" amp I'm kinda sorta shooting for because that would be at ear damaging volumes in a home environment. As much as I love the idea of being Jimmy Herring or Derek Trucks and playing through a Super Reverb on 8...that would sound TERRIBLE in my jam room. And so I'm chasing stuff that isn't a Super Reverb at all. I'm less concerned about the technological "compromise" I'm making to try to get that at the volume I need it at and more interested in "what's the playing experience using this gear" like.
