I *think* all the TV and AV audio still goes through the TV set

very ordinary cable.

Well, that just about says it all really.

The audio stage in most TVs is pretty poor, and if you're routing the AV
audio through the telly then it's going to sound bad.

The audio on my AV system goes nowhere near the TV, indeed the audio in
the SCART cable isn't even wired up. I've heard systems that were wired
up in this way, with all audio from AV (VCR, satellite box etc) routed
via the TV, and it sounded pretty horrible.

If that really is how you've got your system set up, and it sounds fine
to you, then don't waste your money on mains filters, interconnects,
silver speaker cable etc - as if you're happy with the way it sounds
like it is then you wouldn't appreciate the difference any of the
upgrades we've been discussing would make.

Just for the record, I've worked in broadcasting for 38 years, I'm not deaf
or stupid, and have plenty of experience of what many different kinds of
video and audio equipment look and sound like. You may have reached a
"decision" that my home AV setup cannot possibly perform well, based only
on my written description of it, but my own appraisal of it is based on
listening, watching, and comparing. Let's apply some logic please -
evidence first, *then* the conclusion.
