VPI turntable again......

Hi,
I make my judgement on any product based on observation and common scense. I never own a VPI turntable and I never will since I don't believe in their design. The VPI design just don't make scense to me.

Let see some of the VPI's design....like the tri-pulley design. It just don't make scense at all....just the bearing(the one which support the platter) already make a lot of noise and you can hear it !!! Now add three tiny pulley and spinning at high speed.....I really don't know how many rpm. At that small size....may be a 800 rpm !!!! And there are a total three high speed pulley spinning at 800 rpm....It is a truly noise make machine !!!! Where did the noise goes? It has to go somewhere...it won't just disappear into thin air....again you can hear more noise and it all come out from you speaker.

And another design is two motor driving one pully and then the turntable.....no two motor turn with 100% accuracy...there is always some variation in speed...Beside one motor is noisy enough, now add two. Double the noise output. Where did all the motor noise goes? Again, you can hear it from you speaker.

If I made someone angry in my earlier post....I apology. I hope this post help you to understand why I'm saying what I said.

Peace.............

The two motors make a lot of noise, the pulley makes noise too and the platter bearing also makes more noise.

If everything equal, I believe a single motor with a long belt that drive a platter will be far more quieter than the VPI 2 motors/pulley/platter approach.

The major problem with the two motors/pulley/platter turntable is that the motors housing and pulley housing are placing so close together than you cannot isolate them in their own separate isolation platform. Now the 2 motors housing/pulley/platter & plinth sit on the same platform or stand.....and all the noise transmit back to the turntable through the platform.

No matter how hard he tried, the noise still exist and looks like it is getting worse.

That's why it don't not make sense to me. Just plain common sense.

Edle, the tone of your reply makes me think you have some sort of grievance with VPI that may be unrelated to the engineering issues at hand (or ear)... I highly doubt that the "noise" is getting worse in spite of your argument to the contrary.

Aside from the 3-pully system, if you had noise issues with the VPI perhaps your setup of the critical elements was not optimal. At least that's my take on it.

What is your point? Thanksgiving VPI bashing? Be thankful there are people like Harry Weisfeld who have the passion for the pursuit of vinyl playback.

Perhaps try a couple of laxatives - you'll feel better in the morning.

I did find that on my TNT Mk. 5, not using a flywheel was better. I can’t quite express the difference since it was subtle but, the sound in general was more realistic.

I have never heard the motor on my TT make noises or heard it through the speakers, even in the very softest passages in the music. I can only presume that the problems Edle describes were due to faulty setup or malfunctioning equipment.

Happy Thanksgiving to all and best regards.

I applaud you for thinking things through and using logic as a guide. In audio stuff, in my opinion, there is a lot of "voodo" equipment out there that is sold to the most gullible.

That said, a lot of times what ends up being 'right' in any field of evdeavor is counter intuitave. In my opinion, VPI designs (and all other quality designs) tend to be based upon finding what sounds the best to the designer. This involves a lot of trial and error and the end result can end up being very different than would be predicted just by speculation.
