TBH the only thing wrong with the powerscalling is the more you turn it down the more compressed the sound gets and there's a littl bit of fizz.
Nice clips, shows well what Power Scaling can do.
The slight fizziness and compression, at very low levels, is caused by the signal from the preamp becoming relatively larger as the output stage becomes effectively smaller.
It can be avoided by fitting an extra volume control (what KOC calls drive compensation). On amps with more complex preamps, this is easier, but on simple stuff like the VJ, Deluxes and 18 watters, it's trickier to find a suitable insert point. It's not a big problem, as you said, and often reducing the guitar volume a tad will do the same job.
