My basement still isn't 100% done (waiting on doors) but the setup sounds awesome! I was able to watch some of Blade Runner 2049 (in Atmos) turned way up yesterday and was blown away by the level of detail and immersion.

I'm also finding that my in-wall M5's sound much better now that the tv has been wall mounted (it was previously sitting on feet, about 6" forward of the wall). At no point was it blocking line of sight between the M5s and MLP, but it was clearly interfering with the sound field in some way.

Good stuff! I once had an RCA cable that the shielding detached only when the cable was bent slightly...it tested fine in all aspects, but at a certain angle the shielding detached - which is why I suggested you try replacing them.

All three cables were bad? That could mean a bad production run.

I didn't bother testing individually, but based on my previous testing, I think at least 2 of them were bad.

I ordered some Blue Jeans LC-1 from Amazon to test out.

Loc: It's all about the location.
These could be the same cables I bought from Prime Cables about a year ago. One was bad, didn't work at all. PC promply replaced it no questions, otherwise the rest of them(6) were fine.

They've already refunded me. Didn't even need to send them back.

As for sound quality you probably wont be able to notice a big difference. Just a little peace of mind with big burly connectors and better length. {Axiom fam. are big advocates for letting you know cables are snake oil} They've done multiple testing's with the N.R.C. and their findings have shown no one can truly tell the difference.
Luckily majority of these companies produce so many that if anything they'll replace or refund promptly no question.

Brendo, I can't hear a difference between my 12 ga Home Depot cable and my Monster Cable with M80v2. But I can hear a difference with M5 and M100v4. Monster sounds better. You'd have to hear it to believe it.

The bulk Home Depot speaker wire that I've seen is copper-clad aluminum, so that might explain it.

bman, I think when your TV wasn't wall-mounted, it interfered with the "early reflections" curve that Axiom designed to. This curve is responsible for image width, stability and timber. The curve is taken from 40 degrees to 80 degrees across (also 50 degrees up and down but that's not relevant here).

I've always wondered though what level of engineering goes into the on-walls and in-walls. How is the family of curves adjusted for these models? Are new curves taken? If so, how do they account for the wall?

Likely Axiom will remain guarded around these questions. Although the science and characterization methodology around the parametric curves are well-established, there are nuances to testing and interpretation, as well as extension to non-traditional speaker designs, that are company secrets.

Anyway, you have a great system there and it will bring you all a lot of enjoyment. We are extremely fortunate to be part of a minority on this planet who can enjoy high fidelity so we should be very grateful.
