CJ PV-5 preamp, Rega Planar tables, and Magnapan speakers.

Linn LP12

Ohm Walsh, any model. They are pure genius.

Acoustat Spectra Series loudspeakers. Oracle Delphi turntable.

Quad ESL63. Linn LP12.

Technics SL-1200 turntable. Denon DL-103 cartridge.

Oracle Dephi & Michell GyroDec.

AKG K240M 600ohm version. Bought them in the '80s and am still enjoying them with a dedicated headphone amp.

Technics turntable SL-1200 series, particularly the MK2, and: Denon MC head DL-103. Together they make a timeless broadcast as well as domestic combo, with minimum fuss.

Linn Sondek turntable, Vandersteen 2c speaker, Magnepan, and all models of McIntosh amplifier.

How about Vandersteen speakers? They first came out in the late '70s and remain competitive to this day. There is somthing about Vandersteens which makes you want to quit analyzing and just listen to music for hours!

B&W DM12. NAD 3020.

Absolutely, the CD format. More than 25 years old and it still stands high against so many disappeared formats.

BBC's LS 3/5a. Technics SL-1200—this turntable crossed more boundaries than "audiophile" classics like the Sondek, it also contributed to music making itself. It also helped keep vinyl alive during the '80s and '90s. Also, most well engineered Ultra Linear EL34 valve amps. The Michell Gyrodec, Denon 103 MC cartridge, Tannoy Dual Concentrics, McIntosh MC275. From a visual aesthetic POV, the early work by Allan Boothroyd still holds up.

Vacuum tubes!

Magnum/Dynalab FT101/MD90. For over 20 years, this has been a benchmark in analog FM tuner design and the very first units can still be upgraded to include TOTL front ends, tube output, and even onboard DAC modules.

Anything much more than twenty years old appears to be fashionable these days (except people, for whom it's the opposite).
