Why do turntables sound different?

Responding to "james1969"

In terms of TT Bearing Oil, no they are not created equal and I would highly recommend the proprietary bearing oil that George Merrill has developed.

Just interesting reading from a fellow enthusiast and turntable designer.  Hope some insight can be gained and either confirm or refute presumptions, assumptions, and the like.  Happy Listening!

Ralph, would you name those turntables you mentioned that were competent and sounded similar ?
I know, I know, you don't agree aloud that vinyl is inferior to tape medium. Theoretically, maybe not but in reality..

Kuzma Reference, Atma-Sphere 208, Technics SL1200 GAE with Triplanar arm, Technics SP-10MkIII with 12" Triplanar arm. I've heard a much longer list that I don't like and even longer than that are the ones I've simply not heard.

In addition to a solid plinth a robust drive seems to be really important to prevent shimmer in the soundstage. That is why the Lenco, Garrard 301s and some of the early Thorens have a following.

Regarding the tape/LP thing... Direct to Disc is really the only way for vinyl to really show off what it can do. So practically speaking, a tape with good proven provenance is likely to sound better... So in practice on this point I think we are in agreement. I mentioned that provenance thing because it appears that there are a lot of tapes out there that are questionable- its a bit of the Old Wild West on ebay for that stuff right now!

Would love to hear the differences on the above 3 turntables you liked.  You have direct drive and a heavy platter with 3 motors and lighter platter with 1 papst motor.

I would like to hear about the tone, body, decay, attack, pitch, and separation of instruments.

Thanks Tom

Thank you for sharing those links perezzi28.

Are you really serious?  Placing everything but the speakers in a different room is ludicrous and extremely impractical.  Actually, I am sorry to have even responded.  Please relocate to planet earth.
