Part 3 of a 3 part review of the VPI Prime Turntable. I was very grateful for all the online information I found online when choosing this particular Turntable, ...
Thanks for the vids John. I am considering an SDS as a next upgrade. What
is your opinion of it and did you notice a subtle or dramatic change once
it was added into the system?
+John Toon I should also add Jason that the SDS is constantly regulating the voltage output so that the motor receives the exact correct voltage. You can monitor this on the SDS display quite easily.
+Jason Simmons I have only ever used the deck with the SDS, but have to say the speed control is excellent and provides great versatility as it accepts all voltages and Hz. Overall I am delighted with the sound and consider the VPI great value for the money.
Sebastian.......just read my reply again and I am misleading you here. The UK/EUR Hz is 50,but the 60 is correct as US Hz, but the 96 you refer to is the output voltage. This actually varies depending on the land of the motor, for example the voltage is higher a the motor speeds up. Hope this is clear.
+Sebastian Spatafore The US is 60 Hz and the UK/EUR 96 Hz, so the SDS provides great versatility and you can tune the system to provide the exact Hz for the motor.
I used it on a different table but just ordered the Prime. I wanted to
make sure that there was room for the platter to turn with the sensor and
mag in place
Hi, I placed the magnet on the very edge of the underside of the patter. The sensor is at an angle on the rear left of the top of the plinth. The hall sensor on that sensor board needs to be positioned directly under the magnet when it passes in order to work properly. Hope that helps!Drew
The Boos Block is 24 x 18 x 2 1/2". The blocks are Diversitech MP-2C
blocks, for around $0.25 each (twenty five cents).
I had the Cadenza mounted by the dealer, Soundstage Direct
No worries Drew - I ended up spending a lot more for my blocks as I got them from the same place as the block - I ended up returning by Boos Block as I had some additional $$ to play with and went with the Maple Shade. It's all good! :-)
+Vincenzo Baldacchino The blocks support the turntable plus the cutting block just fine. I did double them up, so two per corner, eight total. A whopping $2! Sorry for the delayed response!
+83911scdrew Hi Drew - Are the MP-2C blocks good enough to handle the weight of the Prime Turntable and the Boos Block? How heavy is the Prime and Boos Block combined? Also, did you double up on the blocks to handle the weight or can you use single MP-2C blocks at each of the four corners? Thanks in advance!
The isolation feet are Diversi-Tech MP-2C blocks. They cost like $0.22 each and I used eight total (4 stacks of two, one stack per corner). I believe they are exactly the same product as some other more expensive audiophile treatment blocks (which are resold/repurposed/marked up).
Thanks for posting. I have the Phoenix gear coming and should have the
prime in the next week or so. I see you went with the cadenza black. I am
hoping the bronze works out for me. Did you have to do anything special to
mount the cadenza properly?
That's why I sold all my so called belt drive turntables it doesn't even
run at the right speed for $614 I rather get myself a nice direct drive
turntable it will outperform any belt drive unit just ask VPI.
+Elizabeth Y Michael Cazares Most direct drive turntables like the mass produced Japanese ones (not the very hi end ones like the VPI direct drive for example) weren't exactly pitch stable as their motors constantly sped up and slowed down to keep the speed accurate. They also introduced inner noise artifacts as a result of this "cogging effect". A nice belt drive will keep just as good speed stability but with less noise. Just ask VPI.
The turntable motor and pulley combination is intended to run at the proper speed with regular mains current from the wall. Fluctuations in the power, however, can have subtle effects on the sound of the turntable, especially on long sustained piano notes. The other thing is that you have to measure the speed of the stock table and adjust the pulley position to set the speed at 33 1/3 rpm. On my Prime (see other video) I actually could not get the proper adjustment. This combination of boxes (actually the Eagle PSU unit on the Prime) allows the Roadrunner to measure the speed and the PSU to dial in the right power to maintain that proper speed. The Roadrunner system is the only system I am aware of that monitors the speed and makes adjustments automatically on the fly (other than some older direct drive tables).
