What's the best and/or favorite piece of equipment you've owned? And do you still own it?

Rega Planar 8

Original Snell Type J speakers. I listened to more great music on them than on any other piece of equipment...still have them, but let's say they're retired.

On my best components I actually have two, one is a custom turntable made by Peter with PBN Audio and it sounds fantastic and it’s candy to the eyes.The other is a pass labs X A160.5 mono amps and I no longer own either of them I’m sad to say. My favorite piece is a recently acquired rel 812 sub and I am totally blown away by it, has excellent Impact without boom, spent a lot of time dialing it in but it was well worth it.

CEDAR DCX and CRX, invaluable in dubbing noisy old LPs. got 'em for a song on Ebay. one day i might spring for the DHX [dehisser]. 

First cartridge: NAD 9300, still have.

First receiver, Sherwood S9600 CP, still have.

Fist speakers, Polk RTA 12, still have.

First tape deck, Technics RM240X, still have.

Ive ADDED many components since 1981.
