The dynavector 507 tonearm. Brings the best out of just about every cartridge. It is a masterpiece of visual and engineering design.
Best Component Ever, for the money
The other thread with this title was corrupted in its inception. Let's do this one with NO cables, power cords, isolation devices or tweaks. My vote goes to the Connoisseur turntable (integrated with arm). I don't have it anymore and you shouldn't be able to find one for sale. High end perspective for $150.
