"An amps ability to drive lower impedance loads has no relation to the amps quality."
I can’t agree with this. The ability to drive lower impedance loads means that the power supply has to be up to the task. This would include such things as heavier gauge wiring in the transformer, and other places, and "bigger" supply caps, and that does infer a higher quality.
And more output devices, and more heatsinking...but this assumes an "equal grounds" approach via traditional A / AB topologies with linear PSU’s. There’s rail switching designs, PSU modulating, class D - all kinds of alternate approaches that can be utilized to generate more power and low-impedance handling with less cost.
Boy we are way off topic lol. All good engineering makes certain assumptions about the intended applications and audience for a product. It’s completely valid for Wilson to take the approach they have - for the sound quality they were trying to achieve, the context of the time perdiod, their intended audience (who are generaly NOT cheapskates when it comes to amps), etc. Complete hubris for DR to come in 20 years later and act superior for tearing down a Wilson against the parameters of his TOTALLY different goals and customer base. He wants to show neat "high value" BOM’s and flat FR graphs for his modest boxes (mostly focused on bookshelf form factor) and drive them with receivers, I get it.
