This is not OT but I remember Dau/Clark, when I was just starting back in the '80s. That's the equivalent of Pier now, where you can get surpluses including small-item military-grade spare parts for fighter jets, satellite-based equipment, latest model tanks, etc. at junk prices (caps at P1 to P5 each and wires at P1 to P10 per meter.).
Those items, I was told, were best for audio DIY upgrades. The traders would insist those were superior (made to save lives, even a country, as objective) compared with commercial-grade parts. Got caps back then that replaced dried up parts of my Quad and other old amps and the results were okay.
An engineer from Eastern Telecoms who bought my Quad amp whose huge power caps I replaced with military-grade ones swore low frequency has improved if based on same model Quad that his brother-in-law owned. I also used DIY interconnects back then including tiny pure copper wires from jet fighter wire assembly which I braided for my old ARs, Bose, Infinity and JBLs (got into British speakers only in the early '90s).
But I got tired of those wires after about 10 years of use in mid-90s since they looked ugly and my wife didn't like them, so, I went back to Monsters' latest, such as Navajo Whites and Interlinks. But I still keep those military-grade ICs in my house outside the city. My braided wires (10 covered wires each of high-grade pure copper) I remember, were 6 meters long each. I'll probably install them back, pag na-inggit ako sa mga experiences ninyo.
