VPI Industries SDS Synchronous Drive System - Improve your VPI Table

A great upgrade to just about any table with synchronous motor drive, and a must for all VPI’s.  

Tested in our lab with a VPI table (not required) and it tracked and synced perfectly.  

Like new and well cared for. Includes power cord

VPI SDS Synchronous Drive System Speed Control Device Provides Dead-On-Accurate Speed for Perfect Timing and Lowest-Possible Wow and Flutter From Your VPI Turntable

Designed to vastly improve the performance of any VPI turntable, the VPI Synchronous Drive System Speed Control Device (SDS) combines a turntable motor speed controller and an AC line isolator into a compact component that yields vital enhancements to the overall analog sound. Simply plug your VPI turntable into SDS and hear the improvements a proper motor drive creates: Solid and deeper bass, smoother midrange, sweeter highs, lower noise floor, and deeper imaging. SDS allows for proper calibration of platter speed, ensuring that your VPI 'table spins at a constant speed and, after calibration, operates at the correct speed. In addition, SDS provides individual speed corrections for LPs and 45s in increments as small as 0.01Hz. Such fine-tuning affords the listener the ability to truly "dial-in" the performance of any VPI turntable.

How SDS Works, and What It Does

SDS breaks new ground in clean, accurate power delivery via advanced digital technology and quartz crystal accuracy. It allows for the adjustment of both the voltage and frequency fed to the turntable motor. Adjustments are easily made from the front panel using intuitive, soft-touch controls. The selected output voltage and frequency are shown using large, legible LED displays. SDS slowly ramps the voltage and frequency up or down to the selected value in order to prevent premature motor wear due to abrupt changes. During motor startup, SDS increases its output voltage in order to quickly bring the platter up to speed. Once the desired platter speed is reached, SDS ramps the output voltage down in order to reduce motor vibration and, therefore, the system's noise floor.

Removes Voltage Spikes, Fluctuations, RFI, and Frequency Variations

The circuit used in SDS provides an incredibly accurate line frequency of great stability. Additionally, the electronic circuitry effectively isolates the output voltage from the input voltage, doing away with voltage spikes, low level fluctuations, RFI, and frequency variations. Instead of merely filtering the power line, SDS first converts it to pure DC voltage and then digitally regenerates its own clean AC signal. This approach is superior to that used in many of the other power line conditioners on the market.

Works With All AC Synchronous Motors in VPI 'Tables 

SDS is designed to work with the AC synchronous motors in VPI turntables. The speed of a synchronous motor is determined by the frequency it is fed. Logically, a device whose speed is based on the AC line frequency will function better when a stable consistent frequency is delivered. Constant motor speed translates into a quieter, more faithful musical presentation.

Attention Record Collectors: Finally Enjoy the Correct Musical Pitch

Many historical recordings are not transferred onto modern records at the proper speed. Using SDS, you can now correct the musical pitch of these recordings by varying the speed of your turntable. In addition, collectors that have VPI turntables that run at 78RPM will be able to accurately adjust them to compensate for the wide variation in recording speed used in the 78RPM era.

This item will be professionally packaged and insured for safe transit to your home.   

If we don’t have the original manufactures packaging, we use heavy duty double ply corrugated boxes with Instapak expanding foam custom inserts which has proven in many cases to be better than original packaging.  We also use high quality fiber reinforced tape to seal our packages.  Lightweight items will be bubble wrapped and shipped in a high-quality box. 

This item is available for pickup in Ridgewood, NJ or Union Square, NYC (with convenient parking in the building).

NJ Residents or anyone picking up without a resale certificate will need to pay NJ Sales Tax.

Use the Buy It Now button and we will cover the PayPal fees.

Thanks for looking and be sure to call or text 646.852.2073 with any questions. 

Please also be sure and visit our Audiogon e-store to see the rest of the items we have for sale www.audiogon.com/stores/skyfi

WHO WE ARE 

Skyfi Audio is a small startup business specializing in the purchase, reconditioning, and reselling of select high end audio equipment.  We only buy equipment the we admire and are passionate about.  No mid-fi, no gimmicks, and no junk.  

Each piece of equipment is cosmetically restored and fully tested in our well-equipped lab by an engineer with 30+ years of experience in the HiFi world.  If it does not meet or exceed the original manufactures specifications, it will not be sold.  We are very selective about the equipment we purchase, focusing on mostly analog, high-build quality, American, and European built units.

Through our sister company, which is an authorized dealer for McIntosh, Audio Research, Sonus Faber, ClearAudio, Project, and Sony ES, we have access to OEM parts, service, and support.  If you are local and are looking for any new equipment for the above-mentioned manufacturers, please drop us a line as we can arrange both sales and professional installation in the tri-state area

PURCHASING GUIDELINES

We do not accept or review any offers that do not go through the official Audiogon system.  We have too many items for sale and its nearly impossible to keep track of offers outside of the official system.  Please don’t message, email, or text any offers. 

If you do not see a “Make an Offer” button, it means we are not considering any offers on that item.  

PAYMENTS

We prefer working through PayPal, which allows you to use a credit card or bank transfer.  We do not charge extra for any payment fees if you purchase the item at the asking price.  You can also send us a personal check (which will need to clear before shipping), certified check, money order, or wire transfer.  International clients without access to PayPal should use a bank wire transfer. 

If you are picking up an item, we do not accept PayPal.  You must pay in person with cash, certified or bank check, or wire transfer.  If you make a PayPal payment and are picking up the item, it will be returned. 

TRADE IN POLICY 

We accept trade-ins of equal or lesser value under certain conditions.  Simply ask and let us know the exact model, condition, and the accessories that are included.  Such as the original box, remote, manual, etc.  We will only consider high-end equipment from mainstream manufacturers such as McIntosh, Mark Levinson, Audio Research, Krell, etc. and will typically pass on displays, projectors, receivers, dated processors, and mid-fi equipment of any type.  We will offer a fair value for your equipment, but keep in mind we are running a business and will need to be able to resell the equipment at a profit after investing a great deal of time and resources in testing, certifying, repairing, cleaning, and packaging the incoming equipment.  If you are looking for top dollar we suggest attempting to sell it directly to an end user on your own.

SELL US YOUR GEAR (Working or Broken)

We will also purchase your used or broken gear and arrange pickup if you are in our local market.  Just drop us a note for a quote but be sure to include the condition and what is included.  

HOW TO VISIT US

We are currently operating from a residence in Ridgewood, NJ.  You are welcome to make an appointment if there is a piece of equipment you would like to see in operation before or after purchase.  We have a well-equipped, dedicated listening room with tons of equipment of all makes and models.  We are not a store, so please don’t make an appointment if you are just curious as to how a speaker or piece of equipment sounds.  In essence, no tire kickers please.  

If you are in NYC and cannot make it out to Ridgewood, we can arrange pickup in Union Square (14th Street) after the purchase.   You can call or text 646.852.2073 with any questions or to schedule an appointment.  We can also arrange to install, calibrate, and tune the gear in your listening room if you are local to the area.  This is super useful when purchasing large speakers or heavy amplifiers.  It is also great for ensuring your new turntable is setup correctly in its final resting place.  

Thanks for looking and please send us your email address if you would like to receive a list of the equipment we receive from time to time.  We promise not to bombard you with junk email.
