The VPI Scout Turntable Saga Part Two: More Exciting Updates!

This is a follow up to the VPI Scout Turntable video I released last week. If you haven't seen the first video I suggest you watch that one first. You can access it here:

System Update! Could a VPI Scout Turntable Take Center Stage In My System?

Today I discuss the effect of the new pulley, the ADS Speed Controller, a bit about belt drive turntables in general, some recordings that I was using to evaluate certain aspects of the performance of the VPI Scout.

There are two audio files you can download of the reference track Pace Verde taken from Andreas Vollenweider's 45rpm 12'" single.
The first one is on the Basis 1400 Rega / Rega RB300 / Hana ML set up and the second is on the VPI Scout /JMW Memorial / Hana / ADS Speed Controller system.
Please download and see if you can hear what I am hearing.

Some comments on what j heard on the files and the live playback, both on my system:


More immersive airy atmosphere on the opening sound effect

More impact on the first drum hit, goes lower, more punch and detail

The vocal section is more impressive in spatial character

The leading pluck on the harp is cleaner without edge

The pace is more solid.
Little background details - guitar here and there are clear.

The bass is solidly driving the track

There is a better sense of depth, width and height of the soundstage

Percussion at the end has more sparkle without brightness.

Note: The graph shows the stereo tracks on the Basis on top, the lower two are on the VPI.

From the VPI website:

Send him the info right off the VPI website:

“The ADS design includes two pure analog frequency generators featuring low distortion and noise; a high current Class-A/B amplifier that is transformer-coupled to the turntable output; analog control logic for low noise operation; 33/45 RPM analog speed adjustment controls with center detente positions that are factory calibrated. “

“ • There are separate speed adjustment controls for 33 and 45RPM.

• The controls have a detented center position that is factory calibrated for 60 Hz (33 RPM)and 81 Hz (45 RPM).

• The speed is  continuously adjustable +/- 3 Hz”
