I have a current spec LP12 now with Keel SE, Ekos, Arkiva, Lingo, Linto.
This deck started life brand new in 1986 with Valhalla, Basic LVX plus and Arcam P77 cartridge. The Arm was changed to second hand Ittok in 2001 with new Dynavector Karat 17D2 and then to Ecos/Arkiva in 2007.
At each change - massive increase in detail from the records.
On my office LP12 (a 1979 model) but now circussed, Hercules 2 and chassis mods, I have SME Series IV and Dyanavector DV20. This set up certianly gives the current 'Linn only' set up a run for its money. The SME does work well, despite the comments of weight etc.. You just need more patience in getting the suspension springs tensioned correctly.
