At this level, I don't understand VPI's failure to design around two inherent compromises that VPI is infamous for implementing; 1) a junction box instead of continuous wiring from cartridge pins to connector of choice and 2) ridiculously lengthy armboards cantilevered from the plinth.
As to 2), I don't care how thick the aluminum or alloy or whatever the armboard is constructed of, I don't care how tightly and securely it is clamped to the plinth, it will be susceptible to resonance that would not be present with a better design.
When one looks at how the expense of production is allocated, I see bling predominating over ultimate performance.
