something is very wrong. Call VPI for an assessment. I have the motor which is DEAD quiet on my Superscout.
Alternative to VPI motor for Aries 3?
I have the latest Aries 3 and according to this webpage:
http://www.vpiindustries.com/products_aries3.htm
It has the following description of the motor:
So this is 'supposed' to be a low noise motor, but I can hear the resonance noise within 2 ft, and I believe the cartridge actually pick up the noise which is audible during the quiet passage of a song.
The question is, is there any other motor that's quieter than the VPI??

It has the following description of the motor:
The solid black aluminum motor assembly is almost 10 pounds and contains a low noise 300-RPM synchronous motor with Delrin motor pulley. This is a very low noise system as the fundamental resonance of the motor is at 5 Hertz. Well below the ability of a cartridge to pick it up.

The Teres Verus is the alternative I'm thinking about for my Aries 3. http://www.teresaudio.com/verus-motor.html Mike |
Hi Viper...My wife is an RN. I used her professional 200 dollar stethoscope to search for noises and yes indeed...my turntable is DEAD quiet. No scraping sounds, no hums, no noises of any kind. Sorry if you think you have something with less sound...there isn't any. I checked everywhere on the table, and on the motors, and ...nope...nothing. |
Maybe I'm more sensitive to noise than some, I don't know, but I would not describe my double motor assembly with rim drive as dead quiet. When listening for it, there is a faint whirring mechanical noise but this never is audible during playback of vinyl. I think it's also much quieter than the belts were. I have no experience with it, but it's hard for me to believe that the Teres motor would be significantly more quiet. |
V: Some simple tests. Disconnect the belt & hold the motor assembly in your hands . Visually inspect to assure all moving parts are free and not rubbing . Gently shake to determine the motor mount itself is tight , no loose parts ,inside the enclosure. Should all be negative, turn the unit on. Should hear more than a wisper of motion caused by the movement of air, that motor assembly is not up to VPI standards and VPI should be contacted. |
09-23-08: Crem1 VPI was right, I did notice some low level 'hum' induced by the motor on my rack. My rack is made with an exotic ironwood (30% high density than hard maple). Each shelf is about 1.5 inch thick. Looks like I need to look for some kind of isolation between the motor and the rack. The problem is this isolation cannot be too 'thick' or else the motor will sit too high relative to the turntable plinth. I also have another rack made with 2" hard maple shelves which I bought from timbernation. This maple rack is 3 times more expensive than the ironwood rack. But as far as sound quality is concerned, the ironwood rack blew the maple rack out of the water. The maple rack sounded relatively 'brittle' and 'light'. The ironwood rack sounded 'focused', more 'weight', and more 'sparkle'. I even have a Gingko Cloud 11, which I used to isolate the TT from the maple rack. I didn't like the Gingko sound at all. It sound 'brighter' than maple. So the maple rack and the Gingko platform is the worst $1600 I have spent recently. |
