Does vinyl have a sound?

@mechans , the negative comments on unipivot arms come mainly from me I think. Let me try to explain it carefully so you understand the issue and what to listen for. Cartridges are designed to "read" lateral and vertical information translating it into two channels. Normal pivoted arms allow movement in only two directions, lateral and vertical. There is a resonance frequency associated with both directions depending on effective mass and the compliance of the cartridge. In an effort to simplify construction and limit friction tonearm designers came up with the concept of a single needle pivot. There are several problems with this design. First is durability. All the weight of the tonearm and cartridge rest directly on that single point instead of distributing it. Consequently the bearing wears out faster. VPI owners frequently have to change "needles." Next and more important unipivot arms allow for a third degree of movement and that is torsional which changes azimuth but worse adds an additional resonance point. Because the effective mass in the torsional direction is much lower the resonance point tends to be at a higher frequency, into the audio band. This is going to effect bass and there is where you have to listen. I think if you compare a record to it's high res digital copy you will hear it. High end manufacturer's of unipivot arms have gone out of their way to solve the problem. Graham uses an opposing magnet stabilization system and Basis uses what is essentially a second bearing that the tonearm leans against. Johnathan Carr, designer of Lyra Cartridges recommends specifically against unipivot designs. 
If you are happy with the sound of your system then there is no need to change. If you want to make an improvement then this is a good place to do it. VPI makes a gimbal pivot are that is a drop in replacement.
I am not trying to anger people but I think truth is important also.

To answer your question - YES.  I was at a presentation by the owner of Genesis Speakers - Gary Leonard Koh owner brought six records to listen to all made out of different material.  Each had a sound.  Very easy to hear the differences.  He is a fanatic so reach out to him and ask him all the questions you have on the subject.

Happy Listening.

"Yes Vinyl has a sound. It sounds REAL and Correct."
I agree with Mattmiller. I am often able to find used lp's in very good condition from the heyday of vinyl, generally from the 1950's to the 1980's that just sound spectacular. I am blown away by how some of these lp's sound. There is no cd or stream that sounds like it. 

Also for the guy that mentioned something about a tonearm swaying back and forth Is a bad tonearm, I say BS. Some records are pressed with the center hole not quite concentric, which is what causes the sway. The tonearm is just doing what it’s supposed to do, tracking the record presented to it. I have records with both off center punched spindle holes as well as warps and I can not hear either, as far as a degradation in sound quality. That is the magic of vinyl....despite all the flaws, it still somehow manages to sound great, and sometimes even magical.

It is the sound of music.
