Speaker cable length with monoblock amps?

$15k/$22.5k cables/amps proportion is not what I had in mind.
In any case, as I suggested above, one must be able to tell the difference between 2' and longer cables. And the difference should be real not something bordering non-existant. It will also depend on speakers. There is no general answer. If someone is concerned with resale, yeah, not shorter than 6', if not - listen. And if auditioning is not possible and there is no-one to advise in the paricular case - 6' is probably most reasonable. Personally, I never really think of the resale value. I upgrade rarely and if after ten years I'll have to throw away an amp I paid $5k for - so be it, that's less than $50 a month. I think about performance and try to get the most of it for the least money, after that business is over and listening to music is in order.

The idea that speaker cables have to be a certain minimum length strikes me as an audiophile myth

If that were true, we would all have hook-up wire coiled inside of our speakers.

Help me out. Wasn't it Bob Crump  of TG Audio who said 5 feet or thereabouts was the optimum cable length for speakers?

Ok, maybe, so what is your point?

I have been running my system in different incarnations for 20 years and the one constant was my 22 foot long pair of speaker cables.  Both the speaker manufacturer and amp manufacturer told me there was "no problem" with the lengths of wire.
