We've got an Xtension 10 set up here, and it's relatively easy to set up and match cartridges with.
One of the nicer things about the Pro-Ject carbon fibre tonearms is you can adjust azimuth by rotating the actual tonearm. The tonearm adjustments are pretty easy to do by comparison with some other tonearms out there.
It sounds very good, and the electronic speed control works well. The platter does take a bit of time to spin up and down, unlike some tables and motors that have more torque. So that is a negative if you're used to faster use.
Haven't had any reliability issues so far.
