I suppose much of what I currently run is rare and quite nice sounding. My preamp is custom-made by Aldo D'Urso in Italy. This makes it "modern," although very few of the components are actually modern. The chassis, tube (310 and 311s), input and output transformers, all of the resistors and capacitors and the Daven attenuators for balance are all quite old and repurposed; the only thing new is the remotely controlled volume pot and the power transformer in the separate power supply. My amp, also built by Aldo, is essentially a stereo version of the Western Electric 133 amp--348 input/driver tubes, 349 output tubes, the correct Western Electric input and output transformers, vintage caps and resistors, etc; the only part that is new is the power transformer.
My speakers were made by Strumenti Acustici Precisione, but, I replaced the midrange horn with a circa 1939 Western Electric 713b compression driver and a Western Electric horn (the replacement midrange is free standing on the top of the bass driver cabinet, just like the horn it replaces). The WE 713b is a terrific midrange driver, but, it is now VERY hard to obtain a matched pair of these things.
The rest of the system is more modern and still in production, although the Viva Fono phono preamp is not a common item.
