"…I was more than a little surprised by the level of improvement it wrought from my system. You get substantially improved sound from your turntable and push button speed change to boot….for $159, you really can't go wrong. In fact, I would say it's one of the most cost effective improvements you can make to your system. If this little box works with your turntable, and you don't have an electronic speed control already, you are missing what your rig is truly capable of." – Adam Goldfine, Positive Feedback Online, Issue 31
Speed Box MKII Precision turntable power supply is a microprocessor driven supply designed specifically for Pro-Ject Audiophile Turntables utilizing A/C synchronous motors. The exact frequency and amplitude of output voltage is ensured through the use of a quartz oscillator coupled with an extremely low distortion amplifier to supply the turntable with a pure signal that could never be provided by using the standard wall plug adapter. The net result of this power supply is a very smooth and quiet motor providing a significant gain in audio performance.
