Syntax, if you happen to be commenting on my previous post to your thread, I would like to add a little insight.
Likes or dislikes play into it I'm sure. I admire the Swiss watch like fit and finish of the entire Graham line, it is truly very alluring. It is also truly rare, even amongst a history of many great tonearms and tonearm designer/manufacturers. I also understand and appreciate the fact that Bob Graham makes a tonearm that has functional precision that leaves most others in the dust, IMHO. My concern and my understanding of Conrad Mas's concern with unipivot arms on his table is that his clever suspension is also essentially, unipivot, which together create some basic engineering challenges, and very possibly a poor result in combination with a basic unipivot tonearm. It is an issue of basic mechanical compatibility not synergy to the subjective listener. Personally, my experience as an industrial designer and analogue Hifi enthusiast tells me that Mr. Mas also has a strong command and insight on turntable/tonearm physics.
In the words of Bob Graham:"Once Neutral Balance is chosen for use in a unipivot tonearm, one must remember that both the vertical and lateral planes will be affected the same way; without proper lateral stability, such a design would not have consistent, proper vertical alignment, and the pivot would tend to flop over to one side or another (usually in the direction of the weighted cartridge offset angle mounting). Obviously this condition must be avoided. The answer to this lies at the very heart of the Phantom's design." In brief, the Magneglide system which completely changes the paradigm of how a unipivot arms responds. This could very well be the key for my success with the Avid and on a grander scale be beneficial to almost any TT set up.
A thought about vibrations, the very nature of all record players works on physical vibration, obviously from the source (Lp). It would be naive to believe or suggest that turntables themselves or tonearms for that matter, do not have inherent vibrations both from the source and from the loud speakers or foot falls or a truck driving down the street near by. The object is what you do with them. Material dampening alone is a cave mans analogy to solving this tricky puzzle. Vibration management on the other hand is the ability to control where and when particular menacing frequencies resolve and the properly dissipation of them in areas that don't adversely effect the music. It is a science that is still being pioneered by those with outstanding insight and technical skills. It's obvious that Mr. Graham is unique in that he has shown a strong command of these skills and an amazing standard for both taste and quality.
Lastly, my inquiry was that of supporting observation and opinion on the given subject... I felt this might be a pretty good forum for some help from those intimately familiar with this tonearm in many different applications. What it was not was an attempt to divert the main discussion tangentially. Just looking for a little help.
Happy (analogue) Listening!
