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

Krell ksa100. All original. Getting it recapped this week after 30yrs. Can’t wait. 

Pioneer pl-630tt with ortofon black mm cart. Still works and sounds great. 
Things sure were made well back then. 

I’ve had quite a bit of gear come and go but my Janszen zA2.1 have remained and will always. The best electrostatic sound in a WAF friendly package.

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.
