Which tonearm for vintage Micro Seiki BL-91

Pryso
thanks... I know about the drooping end stub. My previous MA-505 had that problem but me too I thought this was normal. A Denon tonearm that came with the turntable had the same problem so I thought it was the design:-)
Now you are telling me, I realize that I sold it as it was and the buyer didn't ask me anything about that. Terribly sorry!!!!

By the way I have seen that you are quite popular here on Audiogon and you are very active here. Can I ask you one more question.
I love my Micro Seiki BL-91. It sounds much better, punchier, dynamic deeper bass and everything than my previous BL-51 ( with a fixed static balanced tonearm that was sold as a set here in Japan during its commercialization years).
I have been reading posts about "plinthless" versus "plinthed" turntables. Lots of new desings like Clearaudio still have both in their catalogue.
Can I assume that this is a matter of taste? I remember another very popular member "Raul" saying that he has changed his mind about Micro Seiki and plinths. Or is as you stated the combination of the tonearm and the cartridge more important once you have the plinth isolated. and the vibration reduced as well as one can or thinks he can.
I cannot compare, very simply because I don't have the money for new high-end turntables. That is why I ask you ....experienced audiophiles.
Thanks a lot
enjoy the music

Well Tgaral, I might question your judgement in calling me "popular" here on Audiogon. Many others have greater knowledge and post more than I do.

Regarding your BL-91, I can't comment. I don't know if I've ever even seen one.

Regarding plinthed VS plinthless, I've read enough opinions on that to know there is nothing close to any consensus. I suspect it relates to the amount of energy (possible micro vibrations) generated by a given motor unit design. The one point I feel strongly about is maintaining an absolutely stable relationship between the platter and the arm/cartridge/stylus. Why would the cartridge/stylus set up be so critical if that stability was not important?

So my only advice in your case would be to study all the Micro Seiki table designs. Which of their higher end models have the most similar drive system to your BL-91? I believe from their reputation the MS designers had a pretty good idea what they were doing so copying that to the extent possible may be helpful. Good luck.

Thank you Pryso, and all of you who have been sharing their experience and knowledge. I guess the only way is trying and spending money ;-)
More opinions welcome of course
