Hello. I bought a mint Dual CS-630Q DD turntable about a month or so ago, and it has been giving me trouble free performance, and great sound so far. But I do have a question regarding the counter-weight.
Is there an anti-resonance filter built into the counter-weight? And if so, is it the simpler elastimer type, or the more advanced mechanical type? Also, do these need periodic adjustment / servicing? Is adjustment or service even possible?
There is no screw on mine, and no markings or words to indicate the type of technology Dual incorporated into this particular design.
I guess I just want to know this so I can maximize performance if that is possible with this arm/counter-weight combination.
