Not trying to beat you over the head with it, Ian. Just many think electronics are a major contributor these days to sound quality and generally they're not, could well be different from car audio world altho my Kenwood head unit with silly watt ratings as well as the two power amps also with silly ratings I've got hooked up to its pre-outs still do a pretty good job with the speakers/sub I've got in my van.

Putting serious hifi in my van would be silly, tho...just a poor environment.
I can appreciate trying to stay with speakers you like, too, but that is where sound quality really does change. I can appreciate being on a budget in retirement, too....me, too.
This is always a handy graphic for expressing the sentiment you mentioned
