As owner of a Micro Seiki DQX 1000 I would like to add something to this forum :
To start from the most important - this direct drive turntable sounds excellent to me. Actually it does not add its own sound, it is a variable which can be removed from the equation. You will be able to judge other components like arms and cartridges.
Some recommend the use of copper mat to be placed on top of the platter in order to make it sound warmer especially when used with solid state electronics.
There are no issuess associated with the direct drive motor which I can find.
The induction type motor is based just under the platter but it is well enough isolated . At least there is no noise which I can detect. In any case the level of noise generated should be lower than
the one of my tube pre-amplifier (12AX-7) as I don't hear it.
To my understanding a good feature mechanically is that there is no friction of parts .
There is one central pivot shaft which rotates (caused by induction ) and the platter sits on it, that's all.
The quartz control - I don't use it.
The quality of materials and craftsmanship :
I have not seen better anywhere.
The platter is made of aluminium. it weights 2.9 kg and is coated from the underside.
The mounting of the arm base to each one of the 3 legs is metal to metal directly .
There are 2 types of arm bases - standard made of aluminium and the ones designated with G (gun metal).
The G is very heavy. Should provide better decoupling of the arm.
So this deck is all metal work.
As regards the 3 feet isolation:
Yes, they are the only thing that isolate the deck but like it is with all it is a good idea to place it on a dedicated stand.
And there are the bigger Micro belt drive decks of course.
Best to all
