How good is the Micro Seiki DDX-1000 Direct Drive turntable ?

Here is the MICRO DDX-1000 direct drive. Never tried myself, but it is the most compact DD designed for 3 tonearms.

*The question is how good this turntable really is, compared to some other vintage Direct Drives ?


Some information from VintageKnob website:  

The DDX-1000 is the original design, with two sculpted strobe markings around the 2kg / 31cm die-cast aluminium platter. The resulting moment of inertia is at 330kg / cm2 and the top mat in fact covers a thick cork sub-mat set inside the platter itself.

The DDX-1000, in real late 70s modernism is a direct-drive. The motor is a DC-Servo with FG frequency generator reference set through the strobe neon lamp which "checks" how many stripe it sees and rectifies if necessary ; the resulting speed accuracy is of 0,03%.

The starting torque is of 1,2kg / cm and load characteristics allow the DDX-1000 to remain below 0,04% deviation up to a 3g load set at the outer limit of the platter - specs-wise, we're here under the contemporary Sony TTS-8000 for instance...

The heigh-adjustable feet are typical Micro Seiki (or Luxman, of course :) and contain a mix of inert damping (neoprene stuffing) and mechanical damping (spring).

The is no Quartz Lock on the DDX-1000 ; the MD-1000 power-supply box holds the power on/off, start 33rpm, start 45rpm and stop buttons plus two ± 6% speed controls.

The AX-1G to AX-6G tonearm bases fit everything from the ubiquitous SMEs to the Technics EPA-100 or PUA-1600L.

Of course, the motor of the DDX was used as basis for the Marantz Tt 1000 (1979), and that of the DQX-1500 (an updated DQX-1000) for the Tt 1000 mkII (1992). And, as often, Micro's direct-drive motors came from... Victor.


DDX-1000/G :

April 1976 limited edition (really limited : 30 units) custom made in... bronze. Howerever, it is black-looking for the most part, with the bronze only kept visible for the top of the three feet ; the platter was kept in AL and the command box was anodized in all-black style ; even the AX-1/G was in-bronze-but-painted-black...
Names of the people they were made for (and offered to - these were gifts !) were silkscreened on the (bronze...) motor's cache (...but painted black) - a rarity to say the least.


The DDX-1000 naturally spawned a myriad of lookalikes and still does today - perhaps better than the original, perhaps not. Or not that much :)

Chakster, nice setup.
I note a CU-180 on the far 444?


thanks, been working on it for a long time
You have to be careful with CU-180 for LUX platter, because there is a slight tolerance (+/- 0.2mm) between different samples of CU-180 in diameter (this is stated in the original manual). One sample can fit, another can’t. The problem is that LUX platter is like a round frame, look at the edge, the mat must be inside the round frame on the platter and a tiny difference in diameter is critical. 

Sadly mega rare my CU-500 is too heavy for LUX motor and i can’t use it, it was my best mat on SP-10 mkII

SAEC SS-300 and The Mat (Sakura System) is what i use too.


What tone arms do you have in use?

I tried so many, right now i have in use my FR-64fx with W250 and N60, Lustre GST-801, Denon DA-401. Before there was SONY PUA-7, Victor UA-7045/7082, Luxman TA-1, Technics EPA-100 

Ikeda IT-345 is waiting here, FR-64s with B60 too

I have only one tonearm that is impossible to mount on LUX, this arm is EPA-100 mkII

Hello. I am new to Audiogon and this is my first post.  I have owned the MS DDX-1000 since it came to market.  I am the original owner of this turntable.  I am seriously considering selling it. I see that billwojo had some interest in one of these.  If so, or anyone else, please let me know.  I can tell you a few details now.  It is in impeccable condition, including the feet.  The rubber is like new because I have always had a sorbathane disc under each foot.  The entire unit looks as if it just came out of the original factory packaging.  I have the Micro Seiki MA-505 tonearm mounted to an armboard.  That tonearm is a very good performer, especially with medium compliant MC phono cartridges.  I also have two additional armboards, both new (1 in the box and the other without the box), one for an SME mount and the other is the standard mount.  I never had any acoustic feedback issue with this turntable.  Maybe because of the sorbathane and also because I have always had it on a 1" thick granite platform.  It performs quite well and is a pleasure to use.  Anyway, if you should wish for pictures or any further details please let me know.

FWIW: I own a DDX-1000 for many years and so far have experienced the following issues:

1. Strobe light failed (needed to fix internal circuit, this is not (!) the line (50/60Hz) frequency
2. Speed adjustment: The pots needed cleaning once
3. Bearing noise: Disassembled motor and serviced bearing.
4. Replaced the rubber foot insulators with Vibrapods

The above is the summary of issues I encountered over 15 years, so not bad in my opinion and I am very happy with the unit. I have two arms installed (Dynavector DV507/Goldring Eroica and SME 3009/2/Denon DL 103.

Most of the above was already mentioned in this post. Annoying is the missing dust cover. I need to clean the rubber mat prior to each use.
