I had a love hate relationship with my system for a while which was Linn pre / power activ nikas / notts analog/ rega aria / rega cd player.
Never got on with the cd player - so i sold it and replaced the Linn pre and cd player for am ATC CDA2 - very good. The tt still didn't seem to gel, but on the off chance when I bought a Kelly Lee Owens lp which came with a free thick slip mat, I put the slip mat on the tt thereby changing the VTA, everything snapped into place - so really happy now with the system. It gets out of the way and I'm listening to the music. The only upgrades i'd like to do it change the arm from rega to something I can set the VTA, and maybe the heavy kit and wave mechanic plus a rigb cart body for my AT. Oh and a sub - if anyone's got a linn sizmik they'd like to sell then get in touch
