Is this akin to a total medal count at the Olympics? While there may be an overall medal winner, if one's interest is particularized (like being interested in gymnastics, but not swimming), the answer might be quite different. In music systems, I like high efficiency speakers that sound good at low volume and amplification that matches such speakers (low-powered tube gear). In any event, I won't try to pick one winner. My own gear comes from a fairly wide span of countries:
Turntable/tonearm/motor controller: Basis Audio (USA)
Cartridge: Transfiguration and Lyra (Japan)
Phonostage: Viva (Italy)
Music Server/ripper: Naim (UK)
Linestage: custom-built in Italy using vintage USA parts
Amplifier: custom-built in Italy using vintage USA parts
Speakers: Strumenti Acustici Precisione (Italy), with Western Electric compression midrange driver and horn (USA)
Cabling: XLO (USA), Basis (USA) Audio Note (UK)
Power conditioners: Isotek (UK)
