EMT 927 vs. Micro Seiki 5000 or 8000 - different?


Did any one test those machines in the same set up? What was the outcome? Idler-Drive in its best built quality vs. the well rated heavy belts from Japan.

How close is the more readily available EMT 930 to the 927? There seems to be a more available supply of those in North America. Another question is whether there is any person to service them in the USA or Canada? Thuchan, I have always found your posts quite interesting. Your passion for this hobby is quite impressive. How would you compare the Micro Seiki tables which I have been drooling over to the EMT? Best Regards, Bob
Dear Bob,
this is the very good question I will answer when I am back from Vietnam, also being able comparing the sound between the Micro 8000 s and the EMT R 80 by using the same carts and tube phono stages on nearly the same level. I will audition with my new 4 way horns and the two matching subs.

BTW i do know two guys who are owning a Micro 8000 and an EMT 927. I am interested to hear an opinion from them and everyone else who does a comparison in the meantime.

Servicing EMTs is always done by former EMT stuff. As EMT had their own sales organization also distributing STUDER machines there should be some guys out there in North America doing this. I will ask some senior EMT people in Germany.
For servicing EMT's in the US I would contact Dusch directly, he will be of assistance http://www.emt-profi.de/welcome.htm

But in reality look at these PDF's http://www.hans-fabritius.de/en/emt.html at the bottom of the page and it gives the service to be performed.

In reality the EMTs are simple and the schematics are readily available. Best is service by Dusch but then things can be done by competant technicians.

In regards to the 930 vs the 927 I would say that they are in different ballgames, I auduitioned the 927 vs the 930 very briefly in Italy and that was enough to hear a significant difference (both had the 139st). The 930 has less weight, presence an PRAT.

The 930 is without doubt good so long as you get it with the 139st not the 155st. Therefore care must be taken on getting one that has the correct PS. Voltages for the tube phonos are not the same as the later SS phono stages. Van Vliet in Netherlands does make a PS for the 139 phono ic case you do not have one, no idea if it is good.

Even if Thuchan and I disagree (we also agree on many things) my view is that any EMT should be considered as a "plug and play" with its phonostage, Thuchan is using the TT part of his R80.

I have done a/b between the 927 direct to Kondo phono stage and ANJ amps etc....horns....vs the 927 and its 139st (mine is original fully serviced by Dusch and kitted with following serial numbered Telefunkens), well it is quite amazing to see (hear!) how this technology from >50years ago performs.

I also have the SX8000 with FR66s and FR7 cartridge, the a/b SX8000 FR66S:FR7 into Kondo phono vs 927 with 139 is on the agenda in the next weeks.

I lived with my 927 for sometime then switched back to the SX8000, missed the 927. Now back on the 927 I do not miss the SX8000 what doe that tell me?

All fun!
Soundlistening,

one of the secrets of the 927 lies in its higher platter mass. In this respect I think people are right when saying that a higher platter mass is crucial for a good TT.

of course we disagree! why not. I need to show you how excellent a R80 plays without EMT phono stage. You will not believe it.

Did you try an external Kondo phono stage with your 927? The 927 seems harmonizing not so easy with external phono stages as the R80 does.  
Thuchan,

Have you tried the 927 with the plexiglass-plate? That does decrease the weight. Some people say that glass on platters is "wrong" but the studio turntables EMT 927 were delivered for the disc-recording industry as a measurement studio turntable the EMT 927 D equipped with a glass-plate instead of a plexiglass-plate.

When you tap on the plexiglass-plate it is not that solid, a bit flimsy to be honest. Okay it offers the added brake, but know needs that at home??? The total mass of the platter is not that high even with the glass platter plate, much less that our cherished SX8000’s. I have from good sources learned that the 1st R80’s platter was heavier, that the 927’s were even less than the R80 and the last 927’s even less.

I would like to talk about a few other aspects that are, from my modest perspective, important.

1) The torque of the motor: This is one 3-phase workhorse and when you attempt to slow the platter with your hand you see how strong the drive is. Do this on a belt drive and.....you know! When done on a Garrard you can slow it quite easy, and other idler drives are in same category. The 927 has a huge torque and power and as such does offer a great control on rotation. Once documented you realize that the 927 offers rotational stability that is amazing, in fact far greater that that of the TT used for the record making!

2) Bearings of the idler mechanism: Look at those bearings and levers...this offers very solid and stable basis for the power and stability of the motor to get to the platter

3) Distance of idler from stylus: Well the 927 was made for 16” records but we only use them on 12” or 10” (those good mono ones!) and this offers another advantage; the stylus is further away from mechanical contact point of the idler and the inside of the platter.

4) Chassis construction: The cast aluminium is a very solid and high mass base for the tone arm. The fact that the motor is mounted on isolation supports prevents it from transmitting energy to the tone arm. The motor is overpowered; the variations in drag generated in the groves do not strain the motor and introduce the potential adverse consequences.

5) The bearing: It is large diameter and very long offering an extremely stable foundation. Apparently the next best thing is a Neumann lathe that the “ultra hard core” analogue boys use as a TT, your next step?

But to conclude: All of this means nothing in reality. The 927 sounds spot on. Is that objective or subjective? We always attempt to come to rational answers to understand why, I offered some above. The rarity of the 927 (and even more so the R80) make these hard to come by. Many have not been serviced and show the toil of time, I have seen quite a few of those! Thuchan, we both went for fully serviced and as per factory specification machines that work as they were designed, this is the only way to go and it requires a particular dedication. You know that I jumped into the "927" following advice from around the world and from one person in particular with whom I share taste in music, “but” I needed to experience it in my setting and to my agenda. I am glad that at this stage we agree; that you considered that my ears were a valid enough reason for you to jump onboard...

And "YES" I am looking forward to engaging my ears with your R80 & Lamm etc……Maybe we will have another pair of EMTied ears with us?

The Kondo testing is on the agenda, work for the time being guess this hobby needs funding!

All fun!
