Micro SX-8000 II or SZ-1

Kipdent, I had HS-80 flywheel a few years back. A friend of my got it and you used it with SZ-1. He also reported an improvement, but he (how ironic it is!) reported absolutely different improvements. So, I got HS-80 and tried to use it with 5000 and 8000 and with all my desire I was not able to recognize any single difference beside making the Micro’s motor to run a bit hotter.

Now, Kipdent, let me to give you some points that you might consider before recognition of impotent of ambience and transients from flywheel. You use threads, I use belt. There is nothing wrong with threads but threads are very sensitive to proper tension. 1 mm different with threads is the same as 10mm difference with belts. The tension is important and to be able to say anything further I need to know what the tension you use. How long your platter will spin after you stop the power on the motor? Another point – you lay records directly on the metal platter. This way of doing the things has A LOT of problem. The “yellow” platter was made by Micro to accommodate the very cheap, bad sounding, SS amp from 70s. The “yellow platter” if it played with no proper TT mat has a LOT of colorations. You might want to review and then reevaluate you feelings about ambience and transients.

Kipdent, i have the same impression when I tested the flywheel on my Micro - the sound improved. But maybe I hear this only because it should serve me as the owner... as FM login states. So what.

Fm_login, sorry, but I am way past that period in my life when I was young and angry enough to react to a comment as sophisticated and throughout displaying deep audiophile and mechanic insight as yours.
Sorry that basic vector geometry is BS to you.
But that is certainly not mine nor Micro Seiki's problem.

Dertonarm, I passed the period in my life when I was trying to educate people. You stopped react because you lost your anger, I stopped to educate when it not worth it because I got wisdom and experience to deal with currently angry or formally angry audio people. I shared the facts, now to interpret them it is totally up you and others who have interest Micros. I would be worth to mention that I shared them not because my desire to argue with you or because my interest to educate you but rather to prevent you and you-like to spread disinformation and urban legends. If you have no sonic or mechanical insight on the subject then you probably shall not make the statements where you put yourself in a position of being a faulty authority on the subject.

Radicalsteve, applying a damping material inside the platter does not work, I have tried it. Using different TT mats do work very fine, try a sorbothane mat atop the Micro with a layer of very hard rubber atop of sorbothane. I can’t give you specific as too many variables involved but even a basic hard rubber later atop 5000 will do very fine. The 5000 is very simple and extremely good performing TT as is. People invent the false differences about turntables presuming that many logical concussion about TT design leads to sonic differences. In reality the methodologically properly to evaluate the differences in sound between two turntables is a quite complicated task… Anyhow, to ask for intellectual honesty and rational sense is mostly too much to ask from audio people.
