VPI Classic 3 Upgrades or Move On to Something New
@jjss49 I read your early post. So,... it seems you enjoyed some SQ improvement from the 3D arm. That might be something for me to consider. I presently do not intend to drop major bucks on a whole new TT rig. I just upgraded my phone pre to the ARC Ref Phono 3SE. I expect delivery next week. I also swapped out the RCA/SE I/Cs that connected the old phono pre to my linestage for XLR/BAL I/Cs. Together, both changes might make for an interesting SQ improvement. I'll report back. Other than Alan (bigby), any other reactions to the SDS controller?? Thanks |
Hi, The SDS does ensure the platter is spinning precisely at 33 1/3 RPM. It does this by allowing you to vary the frequency (hz) of the electricity coming into the motor. Mine takes about 59 hz. to spin at 33 1/3. Once set, the SDS regulates the electricity coming into the motor so the speed does not vary. I use the strobe to occasionally check the speed and make slight adjustments. I think the important point is the electricity coming into the motor dictates the speed of the motor. Since each motor is a little different in construction and the electricity coming into our houses is not perfectly regulated, the SDS allows you to set the correct speed using a strobe and then adjust the frequency of the electricity so the motor spins precisely and consistently at 33 1/3. I haven't done any other upgrades. My Classic 3 has the original metal arm, the record clamp and outer ring. Most of my listening is Tidal streaming with a PS Audio Directstrem DAC and CDs using a Marantz CD player. I saw a used VPI SDS on US Audio Mart for $800. Sounds like you have a nice set up with all ARC gear! Thanks, Alan |
