Good responses, with Onhwy61's being especially fair and balanced.
Zavato's assertion that, "Setting the VTA should be a one time thing once the cartridge is installed..." would have been better stated as a matter of individual sensibilities and preference. Some of us hear out-of-adjustment VTA (SRA, actually) on a per LP basis and prefer to adjust accordingly. For such listeners, a fixed-height tonearm would be a poor choice, no matter how rigid it is. Rigidly wrong is still wrong. :-)
Roy Gandy espoused several other "keep it simple" views, such as the idea that LPs need not be cleaned to play their best. That may work for some but certainly not for all. One senses that he pooh-poohed audiophile fussiness in order to encourage people to just relax and enjoy the music (and not worry about adjustments that he couldn't be bothered to offer). Keeping the listener blithely happy might stop him looking around at competitor's gear and wondering, is there more?
Rega's are decently made, set-and-forget rigs built to a price point. For the target listener they're a good choice. But above a certain price point one expects more. For some listeners, other rigs will provide more of what pleases their own ears.
