My second system is at the opposite end of the room from my first system.
It contains the items I used full-time in the day bur are so iconic I cannot get rid of them: Simon Yorke Zarathustra (16 built); Zeta arm (said to have belonged to Ken Kessler (because the mounting screws were torqued too tightly); Ortofon Anna (because it is too massy for the lightweight Aeroarm in my first system; Krell KSA50 (Krell's first product); Audio Research SP10 (because...); Audiostatic ES200s I amongst the first good 'full-range' electrostatics.
Still a great system as when it was my main system from the 80s to 1998.
