Albert Porters after market panzerholz plinths

"So a heretofore unknown fault inherent to a belt drive turntable became apparent. "

How can you know the drive mechanism is the reason?

Aren't the two tables best optimized with different tonearm, and cartridge plus also set up and calibrated differently? Any combo of these could account for a difference. Not to mention dirt accumulated on the stylus, etc.

I would not expect any properly set up high end rig to sound inherently muddy and garbled, but I am sure you heard what you heard.

So far in one year I have managed to get only about four delivered.

At that rate and from my list of waiting customers you should get your sample about 2014.

Everyone thank you for your comments and for some of you here for sharing your hard work and effort into this hobby on this site
Though at times some of the threads read like a Republican Democrate debate of sorts though there is something for everyone on this site to follow or criticise this is ok
My experience of using direct drive table is coming up soon,first one is the Kenwood 990 in the nude with a swinging arm board off the x frame and a kick ass arm, FR 64s Up next when all checked over will be a Technics SP10MKII tried nude and with heavy vibration obsorbing plinth
Sounds like fun to me.

I have responded to very few threads in the time I have been reading this forum, mainly because I lack alot of listening experience, but I can't help responding to this thread. Based on Arthur Salvatore's review of the re-plinthed Lenco, I recently changed from an Aries 3 with super platter and jmw 10.5i tonearm to a Lenco drive (motor and idler) in my own diy plinth, a Graham 2.2 tonearm, and the super platter. I used the same cartridge (XV-1s). I was stunned by the difference. The vpi was a fine table, but the improvement in transient response, clarity and bass was so blatantly obvious even to my relatively inexperienced ears. Some might argue it could be the tonearm difference but I believe it was primarily the idler drive vs the belt drive. The original poster asked if re-arming and re-plinthing these older tables advanced analog playback - my answer is a definitive yes. Note that I can't speak directly to the technics DD table, only the Lenco but I suspect results would be similar. I can't see myself ever going back to a belt drive table.

It's not as though we weren't aware of any of those variables. Everything was checked and rechecked with the same result. What I am describing was a the result of the platter being unable to maintain angular velocity which would have been well known to a turntable designer or other expert but not to us at the time. Live and learn.

II have a training that permit to know in " hours " what you could take " many months ". I already explained this to you in other thread even you " live " how fast I can detect " errors " or virtues due to that specific training.

Well, if I had only known this beforehand. I am now bowing from the knees.
