Straight tonearms without offset angle

Yamaha also have a Vintage Design, as well as Stax and Micro Seiki also experimented with similar designs, but not zero offset that are now Vintage Models.

Yamaha also have a modern design for the Tonearm used with the GT 5000 Table, this arm is wired with PC Triple C. I am an advocate of this wire type, and also with experiences of having been demo’d a Tonearm with this wire type, used as a continuous wire from Cart’ Pins to Phono’ Input. Using such a Wire, as a Wands Signal Path is a very wise choice.

Truglider is another Brand producing Zero Offset designs.  

Stax and Micro Seiki both produced Straight Arms, but not Zero Offset .

When looking at the Models it does seem a Zero Offset can be created, a little thought for a Headshells Cart' Mounting Mounting would be the ideal place to modify.

Both Stax and Micro Seiki has a removable Headshell of the Flag on a Flagpole Type.

There are simplistic alternative methods to attach a removable Headshell to the Wand that are a substantial improvement. The Zero Offset seems to make this as a option even easier to achieve.

As made known in other Threads, I am at some point in the future to be demonstrated a friends TA Design as a Underhung Geometry, with them producing a alternate Headshell for their TA.

There are Headshell designs in the following link that will attach to the Wand, these designs enable a rigidity not usually achievable from a Bayonet attachment, the ones in the link are much closer to a formed Headshell on the Wand

@mijostyn would make easy work of producing one of these alternate removable Headshells if the OD of the Wand is supplied. There will also be a need for getting over any confliction held with Underhung Geometry

As Stated on many occasions:

 "There is a principle which is a bar against all information, which is proof against all arguments and which can not fail to keep a man in everlasting ignorance-that principle is contempt prior to investigation."

Where investigation and experiences off are not easily attained, an open mind is also a wonderful companion and failsafe against everlasting ignorance . 

Audiogon is the site I visited for many years prior to Joining, where much of what I witnessed was the bemusement of plenty who were contributing.

I joined with an intention to help simplify things, my suggestions are reachable, achievable and aimed at the observer from the side lines or future visitors who may discover a thread I am contributing to.

I have witnessed bemusement offered up on this forum that does come with a cost for a reader. My causing bemusement comes with Zero Cost to a reader, but does seemingly stir further thought for some, which is constructive, is my amusement for myself, there's nothing like seeing the penny drop occasionally.

As when Joe Biden was on a Official State Tour on an Island in Europe, where he had invited an encountered on a Bridge miming Fisherman to a Pub. After having bought the Fisherman's third Pint of Guinness, following the Bridge encounter. Joe inquired " How many did you Catch from the River" to receive the Fisherman's reply " You're the First today"  

@ozzy62 I live in a Country where forgiveness is the Proposed Fundamental.

There has been the "The Abolition of Capital Punishment",

I won't be rehabilitating my Selection of Capitals to be used for Words within a written Sentence. 

It really doesn't matter what the naysayers are saying nay to. There forte is remaining where they are and professing what they have. 

The better types, to take a lead from, are those who moved on to the Viv from the tools naysayers are advocates of, or those who get their most satisfying experience using Underhung Tools and Over hung Tools in conjunction, where the differences are seen to be the bonus.

Each to their own on such matters, unless one likes to get the zGloves On. 

@reimarc My own experiencing of changing to a new Tonearm has similarities to your own.

I was first introduced to the TA at a forum event, where during a range of different equipment being demo'd, much of what was individuals designs for an Idler Drive, I heard a demo' that caught my attention.

At a later date, I was invited to the individuals home that had demo'd the set up that was certainly very well thought off and for me indelible as an experience.

I was introduced to the design that was selected to be used and the importance of particular materials being used as exchange materials, and the very tight tolerances able to be machined for the interfaces.

Further comparison demo's were done between TA's, with the result being I bought into this design for a TA, and have not felt to date a change is needed, even when being involved with a few changes that have been produced for the TA since my becoming an owner.
