Heh, ok, posting written rather quickly... but you get the idea.

In your opinion of course.

In my experience, yes, speaker cables do make a difference to the
sound. As do interconnects to some extent.

But can you hear the difference when you don't know which cables you are
listening to?, that's the question.

Can you hear +/- 1dB ? or +/- 0.5dB ?

I can assure you some people have NO trouble doing so.

Rather depends on frequency, level and whether you're listening to tones,
noise or programme. It will also depend on whether the +-1dB or +-0.5dB
change is across the band, i.e. a level change or, say, at 10kHz, where is
would have the effect of a tone control. +-1dB change on programme is pretty
difficult, but some would manage it, +-0.5dB is tougher still, and most
wouldn't manage it on most programme material.

I would broadly agree but you ought to try the +/- 1dB test yourself before
becoming too dogmatic.

Explains the 'golden ears' thing though.

I do believe that on extended listening I've heard - 0.3dB @ 20kHz. I was
younger then of course.
