Doesn't tube normally have a nicer tone as well? I know its all a matter of opinion but i've always enjoyed tube amps more than solid state. That carvin looks very nice. From a tone standpoint do you think the carvin poweramp would make much of a difference in tone than the rectifier power amp?
I've never played a rectifier, but it wouldn't matter if I had. There's no way to predict what will work for you and your gear, based on somebody else's experience with this amp or that amp. There's only one way to find out if you're gonna like a piece of gear or not. Sometimes that means gambling on something, and dumping it later if it doesn't work out...its like a cheaper version of marriage, lol.
As for tubes vs solid state...that argument will go on until the sun snuffs itself out. And at the end of the day, you either like it or you don't, so who cares what's in it? Purist tone-snobs will pontificate loudly and at length about how nothing but a 'vintage' tube amp will do, and that modeling amps are soul-less, tone sucking instruments of the devil. I've even heard people go on about being able to tell the difference between what kind of power tubes are in a given amp...EL34's vs 6L6's vs 5881's....blah, blah, blah. With some rare exceptions...most of these people are lying, but I digress.
Over time, tube amps are more work, and more expensive to maintain. Retubing an amp is not cheap, and as the replacements are now entirely made overseas, consistency can be an issue. They are also prone to more problems, tubes becoming microphonic, etc...and too much jostling around and something is gonna break. Also, they have a nasty way of sounding great one day and absolute crap the next. By comparison, a solid state amp will sound the same every time you turn it on, and you can throw it down a flight of stairs, and 9/10 times, it'll still work. And even if it doesn't, whatever you broke will cost pennies on the dollar to fix, compared to its tube counterpart.
I've had the Carvin for years....I like it, and I still gig with it. But my backup is the Spider IV HD150, and before that it was an ADA Microtube 200...single rack space, solid state power amp (they stuck a pair of 12ax7's in it somewhere, hence 'microtube', but its really a solid state amp). Because those things will always turn on, and always work.
But soon, I'll be going FRFR. Smaller package, and I will be able to really get the most out of the 500X and my JTV that way...just haven't decided if I wanna go with the Stagesource stuff, or something else. The price is a little steep...
