VPI SDS Whys and Hows?

Not sure but you would get better sound with SAMA.Try giving Sheila a call at VPI and if she does not know Harry or tech (know Mike is great resource) and ask.You could go stock or just call Blue Jeans or cheap supplier.Don't think PC makes any dif into so using Hubbel or Radio Shack it's not a big deal.SDS was good choice and SAMA would be to.What arm are you using?The ET vacuum model is really popular combo as is the SEM or VPI's own.Deserves decent cartridge as well.Did you notice difference with SDS?

Hello Chazzbo, I am using the Audioquest PT-7 Arm, with Expressimo Weight, older AQ Emerald Cable, and Benz Micro HO Glider. run into both the SDS, and Pre-Amp is the Sutherland PhD.Getting the SDS, and PhD pretty close to the same time, I have noticed one of the many improvements in that the noise floor had dropped quite a bit, but honestly cannot attest accurately how much influence the SDS had played?One thing the SDS did certainly do, is for the first time in the 10 year ownership of my HW-19 Table, I was finally able to achieve dead on accurate Platter Speed, and this seemed to solidify the music, and seemed to help with what I thought was very slight Wow-Flutter.I have read a few reports, and also a couple of personal recommendations that the SAMA, (and the Noise Floor of course) did benefit from the use of an Aftermarket Power Cord, one using a Signal Cable Cord, the other a Cardas, but to be honest, I cannot immediately, and accurately recall if any of these folks were implementing the VPI SDS as well?Seeing that it looks like an Aftermarket Cord with its larger male Connector would be difficult, if not impossible to attach to the back of a Stock SDS, I get the feeling that no, they were most likely not using an SDS with these Aftermarket power Cords.

I have a new Superscoutmaster and the cord fits absolutely perfectly into that cutout provided on the SDS. Why would you want a new powercord? The SDS fixes electrical problems and feeds it to the motor(s) You might make the sound different, but I doubt you will make it better. Richard Vandersteen told me that very thing when I asked about better power cords to my 5A's

Hi markd51,

TT motors are fly weight power consumers. The VPI HRX motor system consumes 14 watts of power, and that's for a 2 motor drive unit. An SDS drive will drive 2 of these 30 lb units, 100% overkill. Do we need a 15 amp connector to power a flea power motor? Do we need to spend $$$$$$ for an after market power cord?

My solution seemed simple, at least to me. I replaced the power cord from the SDS, with a 22 gage, SHIELDED cable to the motor. I will deliver the power to the SDS from an APC smart battery back-up supply. This only augments the advantages of the SDS. Will anyone be willing to modify the electronics of the SDS, maybe, but probably not, but it's not a big deal.

I have yet to hear if the ideas I've presented will actually make me happy when I turn the system off, and go to bed. -------------------- Next month I'll be able to see how everything works out.

Mark sound like you have really nice balanced system,.Have a buddy who also has the PY7.It would be the one thing I'd swap out 9Rega 300/600?Origin Live 250?Eminent Tech?VPI 10 or 10.5 Memorial).You have excellent phono stage and cart and I have always been deferential to phono and cart and stage as opposed to more "balanced" parts of change but I think you have those bases covered.I would again call VPI and tell them about your problem (they may give you low cost option and general advice on deck).Another good resource I have found is talking to Bes Nivera at Music Direct who has heard most everything out there (and it's various combos).I would think that he could put in valuable 2 cents on PC,arm or other deck issues since he sells everything you have.
Good luck
Chazz
