Being on the older side, I have a lot to choose from.
Like many who have owned the QUAD ESL, they are number one.
Then there is the unique Townshend Audio Rock Turntable, mine being the Elite/Mk.2 version. Mated to it is another keeper, the Zeta tonearm.
Staying with English companies (yes, Max Townshend was an Australian, but Townshend Audio was---and remains---based in England), there is the equally unique London (formally Decca) phono pickups. I bought my first Decca in 1973, before many of ya'll were born.
Already considered classics, my trio of Music Reference power amps (RM-9 MK.2, RM-10 Mk.2, RM-200 Mk.2) will remain in my music room until I die. Don't hold your breathe ;-) .
Amongst Magneplanar enthusiasts, the Tympani T-IVa remains a favorite. I don't currently have a room big enough for my pair to be properly situated, so they are sitting in their original shipping cartons, waiting for the opportunity to once again sing.
