That wasn't really my intention, but the "hit and run" future of the musician is sort of written on the wall. Nearly all of the clubs I play don't have parking for their bands, and there tend to be 4-5 bands playing a night. Parking in a city like LA is tough, so a long walk carrying a tube head and making a second trip for a big 8x10, and then maybe a third for your basses\pedals\etc isn't fun. The whole "band van" thing doesn't really pan out for local musicians, and people are moving to smaller and smaller cars for a lot of reasons.
There's working harder and then there is working smarter. This isn't a strong man contest and I'd call moving 300lbs of gear more than a "little" work. If the pay is barely enough to pay for gas (if there is pay) then the pay certainly isn't enough for spinal surgery.
As far as I'm concerned SS is SS. The class D amps are just smaller SS. My Shuttle was plenty loud, but was a little light in the low end department. The D-800 I just got more than capable.
