Micro Seiki, or TW AC-1

Raul,
I try to learn new things too, sometimes it is not audio related. I happen to use my Micro to enjoy music, not as a "tool" to attack your personal pet hate, the German group. :)

Dear Jaspert: My experiences and opinion about MS was way before I knew them, you can confirm it through some posts by me.

With the german group or with out it the fact that the arm board in the RX-5000/8000 are mounted just/directly on the TT footers where exist no single way of internal/external damping on any kind does not change the wrong wrong TT design if for no other factors by that one that makes a heavy degradation to the cartridge signal. Every single resonance/vibrations of any type pass through that arm board/footers.
What in the hell has to do the german group or not?, that's a fact a nocive fact for any cartridge mounted down there and you know what: that's what you are hearing: heavy distortions. The fact that you enjoy it menas almost nothing but that you like those distortions even if are bad ones and you can't do nothing to disappear it.

I know that you as Thuchan don't learned yet about and likes that wrong design and you know what?: that second platter they use as Dave use too help in nothing to the arm/footers MS degradation focus!!!!!

I'm not against any honest person and certainly against no single audio manufacturer what I'm against is of any high distortion focus and I share my opinion about.

I know that like me we need to learn many audio subjects, some of us took more time to others but at the end the success on audio systems depends on that audio learning subjects.

I posted several times for several years that the main differences in between home audio systems is how high or low are its distortions and to improve our each one system we need to learn we need to be aware of several kind of system generated distortions and its precise focus. In the MS case the arm board is one of the generation of distortions focus and that's why today I almost avoid to make no single serious test of any audio item through my MS one.

Certainly you posted what is a misunderstood of whom I'm. I hope that with this could be more precise and clear why I posted what I posted here or elsewhere.

Regards and enjoy the music,
R.

Glai, I experimented with flywheel arrangements. By doing so I realized that the motor management is very important and needs a precise steering. I found it in the VPI SDS. I use the MS Motor (SX 8000 II) and the HS-80 ( 8000 II) in combination to control the vector forces. From my opinion whether one uses a TW or MS he should look for good and precise motors and an exact and stable motor management. I would not go for a three motor design.

Regarding the quality of MS tables I have seen big differences on the markets, in Japan, Germany, France and the US. It depends on age, care and usage. the best samples I have seen in Japan.

Raul makes an interesting point about controlling vibrations both internal and external. As both the MS and the AC-1 are unsuspended tables, I'm curious if Maril555 has considered some kind of isolation platform.

I used one under my unsuspended turntable and it made a tremendous difference.

Every single resonance/vibrations of any type pass through that arm board/footers.

Raul has a point.....only if there is a direct connection between the 'footers' and the armboard support base?
It is not clearly evident to me.....that there actually IS a direct connection in either the MS or the AC tables (which share a similar armboard support concept)?
What IS clearly evident (in both tables).....is that the armboards are directly connected to (and supported by) the bases....ie plinths.
How much structure-borne feedback is allowed to travel through the supporting feet, into the plinth, into the armboard support and thence into the armboard itself....depends on so many factors that without supporting evidence......it would be a rash man who makes such a bold claim?
Nevertheless.....the fact that Continuum goes to so much trouble to 'isolate' their armboards from the plinth in the Caliburn and Criterion turntables.....indicates some obvious benefits in doing so?
In the absence of a really sturdy wall-hung shelf support for the turntable.....a Minus K isolation stand would always be an improvement for any deck...and owners of MS turntables seem to be unanimous in aclaiming the improvement from the use of such devices?
