New vs uses in your current setup

Interesting topic.  Stirred up some cobwebs in the way-back machine.

As a retired dealer/speaker nerd, all of the source components, cables, and amplification in my system are discarded demo gear, and rep samples.  "Hey, Mr. EAT rep: That's a nice turntable.  When it's done making the rounds in the territory, send it my way."  So, technically, ALL used.  With a full factory warranty.

On the other hand, I designed and built my own speakers from 100% new parts -- raw drivers, caps, coils, etc..  After 35 years they are well past the "gently used" classification, and solidly "used/vintage."

Thanks for the topic.

100% used or demo for me. I am a very patient shopper and I buy carefully.

My system canton 9k speakers Technics SGU700 integrated,maker interconnects, monster m2 speaker cables, martantz cd 6006 player all used all trouble free (hope I did not jinx myself) for years. Before that bought all adcom gear pre &power amps, snell c2 speakers,same interconnects.quick story within hours of my installing the adcom system one strand of speaker wire touched the oppisite speaker wires from it resulting in immediate amp dying. I called adcom which was 30 mins. from my home in new Brunswick NJ at the time and  for a dozen donuts they went through the amp and fixed it like new! I sold it after years of flawless service just to try something different.In hindsite I should have kept it for another room. Adcom Good stuff, good people.

All used except my tt (Rega P10), cart (Hana Umami Blue), and one pair of speakers (Revel Performa F328Be).

With careful research of both potential items and sellers I find that you get unbeatable value from buying used. Careful and diligent are the operative words, though.
