Hello,
Everything the Cetech does is positive and in no detracts from the pacing and drive of the Linn. I changed both the subchassis and the Linn motor for the Origin Live motor and outboard power supply about a yaer ago. It's certainly like having a new turntable born from the same mother.
The Cetech alone resolves much more detail and brings everything more sharply into focus. The OL upgrade gives a much wider, deeper, and better 'arranged' soundstage. the first thing you will notice is that percussion is shockingly realistic and 'in the pocket'.
Either upgrade is a significant improvement. Together the total improvement is greater that the sum of the parts. And how much is the sum of the parts ? The subchassis is $200 to the US. The OL upgrade is around $500. You may want to check with Galen Carol Audio for pricing. He carries most of the Origin Live line in the US.
Have fun,
Mark
