The linear trackers are about as automated as could be back for an LP playback device. It would automatically recognize the size of the disc and adjust speed. Once it's closed you move the stylus from track to track, forward and backwards using the front touch panel controls.
The SL-D1 was build like a tank and had a locking enclosure that was demonstrated by hanging it vertically on a wall where it would still play! The SL-D10 that I have was a more affordable unit that wasn't built quite as robust as the SL-D1 but used some of the more conventional materials that were common on their more popular turntables.
The OEM cartridges were junk (Audio Technica?) and I upgraded the sample I have with an Ortofon OMP-10. It's decent as a playback device and I'm told by using the optional replaceable stylii, I can take the OMP10 and the SLD10 up a notch in musicality.
