Just looking at the gear I own:
Speakers (Dynaudio): Danish
Subwoofers (Martin Logan): American / Canadian
Turntable: (Michell Gyro SE): British
Tonearm (SME, Jelco): British, Japanese
SUT (Hashimoto, Lundahl): Japanese, Swedish
Cartridge (Audio Technica, Nagaoka): Japanese
Reel to Reel (Revox): Swiss
Electronics (Devialet): French
I guess the only significant "audio nations" I'm missing are Germany [forgot about my RME ADI-2 Pro in the office], Netherlands and maybe Korea (if Korea counts as a major audio nation)
How does your gear break down?
HTPC' components from the Republic of San Marino (my own built, 2015)
USB DAC from Andorra, it works great although I have been forced to entirely translate into Spanish (Castilian actually) my Linux Ubuntu so that they can comfortably exchanging each other via the USB 2.0 digital stream protocol ... Yeah the drivers sometime suck
Pre-Amp from the Grand Duchy of Luxembourg. Never been so happy abt. an Hi-Fi electronic so far, the Grand Duchy' 1st secretary takes the effort to call me every Monday-morning at abt. 7am (on my cell phone though, so I should remind myself to keep it ON when I go on bed at 11pm on Sunday) checking whether I have had a nice weekend listening to the GD of L proudly made Pre-Amp ...
Amplifier from the Principality of Liechtenstein. Here I said to them : look guys, I am going to take with much pleasure of mine your proudly made amp but pls. do not attempt to call me on every Monday-morning as I have other calls to handle actually ... They said OK on that condition, so I have taken it.
Speakers. These are from the Principality of Monaco. Luckily, here they do not care too much abt. / bother you as an Hi-Fi customers of theirs unless you own a Principality's bank account with a min. of 3 millions EUR / USD (for whatever reason they apply an 1:1 exchange rate between these two leading currencies)
Cables. I have been evaluating different offers, the most appealing one was from the Nation of Brunei, however - at the end I have decided to retain a cable vendor closer to France. They are based on the island of Jersey (the Bailiwick of Jersey within the Channel Islands), so a Crown dependency, which means they are backed up by Her Majesty for any sort of malfunctioning. I believe it's must to have in today's Brexit process.
All that said, my
preferred system is set up in my bedroom. It comes from the Vatican City State with a signed and duly stamped authenticity certificate of Holy Blessing from the Pope himself. The divine sound rendering one blessed man can get out of it is just ... Divine!
