Funny thing about this. As one who focuses primarily on legacy equipment I own one KLH Table Radio.
I own six (6) sets of AR speakers, all from the Teledyne days, all in active service from 3as through Athenas. I also own one-each of their amps, receivers and tuners.
I own an Advent 500 SoundSpace control and a 100A dual-Dolby unit (matched to my Revox A77).
I own a pair of ADS speakers out on loan.
I own three pairs of Koss headphones, including their electrostatics.
Other equipment in the inventory includes:

Revox A77, A720 & 722, B225, B215, B290
Harman Kardon Citation 16, 17, 18 & 19, ST7, ST8, HK2000 Cassette.
And several shelves of Dynaco tube and solid-state.
Main speakers are Maggies.
Multiple Sony Changers, 200 & 5 disc, all from thrift-shops.

So apart from the Revox, Sony and the HK2000, everything is from the US and from 'back in the day'. Much of it via dumpster-dives, and purchasing repair-shop leavings as my eyes and ears have always been larger than my wallet.. I did drive 1,200 miles round-trip for the Maggies, however, after a friend auditioned them in-situ. The price was that good. They are truly worth it.
