The PX-99 is an auto-lift turntable with a silver exterior and black top. Like most of the Luxman models, you can switch off the auto-lift (or auto return) feature, which I’ve found is handy on (just one) extra long record with my PD-288. The PX-99 has a twin that has an aluminium top surface and woodgrain exterior, the PD-290 – they are identical mechanically. There are also fully automatic versions, the PD-291 and PX-100, that have either an aluminium top with woodgrain exterior, or a black top with silver exterior respectively.
The motor is a really excellent Micro Seiki one that had the lowest rumble Australian Hi-fi ever measured between 1981 and 1985 using the Thorens Rumpelmesskoppler rumble test adaptor (which eliminated the inaccuracies of test records) - it beat some much more expensive opposition that cost up to five times as much. The tonearm is also pretty good, like most of the Luxman arms, and works well with most high compliance cartridges that track at lower than 1.7g – the Australian distributor used to pair them up with Grace MM cartridges, which were a good match.
The only real area that can be improved is the base, which is a bit light, but extra damping can fix that. It was really the last quality turntable series that Luxman put out, just before the ill-fated Alpine buyout that almost ruined the excellent Luxman reputation and finished the Luxman name until it was revived recently.
