Grado SR80x Prestige On Ear Hi-Fi Headphones Sumiko MM Cartridge the difference being the upright

the difference being the upright either being in natural bamboo (as pictured above) or in all black

They are stable due to their wide base and can be used 'as is' directly under items (point down) or if moving the items regularly double sided tape or blue tak can be added (not included) to hold them in place (they are not threaded)

so naturally suited my predilection for lower powered single ended feedback free valve amplifiers

A huge variety of different connectors and lengths are available for all sorts of different applications
