According to Audio-Technica, rather than sensing the speed of the platter to adjust rotational speed in the usual manner, the new AT-LPW50B instead monitors the speed of the motor, with the company saying: ‘To further ensure accurate, noise-free performance the AT-LPW50PB is equipped with a professional-grade die-cast aluminium platter, driven by a speed sensor-monitored motor that ensures continuously accurate platter rotation.’ Audio-Technica specifies wow and flutter at less than 0.15% (RMS weighted) and signal-to-noise ratio at more than 60dB.
The Audio-Technica AT-LPW50PB comes with a straight carbon-fibre tonearm fitted with an AT-VM95E moving magnet (MM) phono cartridge which is pre-mounted onto an AT-HS4 universal-mount removable headshell. The mount enables easy cartridge changes. The cartridge can be upgraded by replacing its stylus with another from the AT-VM95 Series of replacement styluses.
The AT-LPW50PB’s built-in phono preamp has a 35dB of gain, so it can deliver 200mV to the input of your amplifier or powered speaker, but if you’d prefer to use your own phono pre-amplifier to provide gain (and RIAA equalisation), it can be bypassed, in which case you’ll find that he AT-VM95E has an output of around 4.0mV (@1kHz, 5cm/sec).
