Inexpensive speaker cables: any experience?

I was thinking about upgrading my Transparent Super Bi-cables; but, yesterday I grabbed a tool and re-torqued.  On a few of the binding posts I heard an audible "crunch".  And when I resumed listening - wow!  They sound like new speaker cables.  I believe the metal in the spade terminals can crystalize and breaking through that will increase conductivity.  The difference was quite audible.

They claim these are hand woven - appearance & sound quality are much better than those customized by machine.  Teflon covered, 16 strand core silver-plated OFC copper.  I ordered enough for tri-wiring my Spendor SP9/1 speakers.  I'll let you know how they sound.

1.5M/1pair：75USD (2-2 Y spade terminals)

1.5M/1pair：95USD (2-4 Y spade terminals)

I'll let you know how they sound.

Yes, the spelling does inspire confidence - for sure!

I'm just happy they're not counterfeit name-brand cables - yikes.

I bought a preamp and later an amp from Queenway - both sound great; better than expected.  He seems to know what he's doing.  As always, the proof will be in the pudding,
