The one piece of gear you will never sell


So much gear comes and goes, but do you have any keepers for life? 

For me, I'll never part with my Zerostat, LP12, and MR78 tuner. I think. 


128x128zavato
Esoteric K-03. Sold mine once and bought another one two months later. Incredible CD/SACD player and DAC.

Never say never. My Audio Research SP3 is the piece I truly hope to keep forever. I guess if the right offer came along I would have to consider it. 
Hi, I would say my very high maintenance pair of Graaf GM200's and the Graaf Modena. I would add my AMR PH77 and Reimyo PAT-777 :) I own a lot more gear but these are the pieces that I really don't see letting go.
My kenwood tuner KT 8300 I bought it brand new in eBay two years ago.
My silverline minuet supreme plus. I always find a use for them.
