Military grade

@stevecham 

can you imagine the excitement (read audio butterflies) when I found out that an extremely limited supply of wire would be made available from the SR-71 Blackbirds.
 OMG!   Wire conditioned and aligned at Mach 3+ and an altitude of over 80,000 feet.....Combine this wire with your Seawolf deep pressure depressed (oops, meant compressed) wire and there we have it.  A spectrum so vast, sub-bass beyond Nemo on up to the Stratosphere.  Articulation and stability over three times the speed of my hearing...... my heart skipped a beat just thinking about it.

I can neither confirm or deny the SR-71 max speed or max altitude. To summarize, mil spec wire or cables has nothing to do with sound quality.

Of course they do. The MIG could blow things up while the Blackbird could only take pictures, but what pictures!

Also, wire from the bathyscaph Trieste went to the bottom of the Mariana's trench, now that's pressure treated! The sonics must be subterranean.
