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

Dear Thuchan, I assume that everyone would love to build
his own 'dream speakers'. Anyway I would. My curiosity is
about the drivers. I know that A Capella uses some midd-dome for the range of +/-300- 50000 Hz. Then the Usher horn uses the TAD coaxial driver (version Pioneer) for midd/high in a three way system. If I understand you well
you are using the TAD coaxial beryllium driver(?). If so I am not able to understand the need for a 5 way system.
Ie even in the case of an extra midd/bass one should think that a 4 way will be adequate. You must have some specific reasons for your choice. Will you be so kind to explain?

Regards,n

Dear Nandric, I have a 4 way horn system. I will use some additional subs which I can use for Stereo support as well as for 7.1 surround. The TAD drivers are TD-4001, TD-2002 and Exclusive ET-703. The horn is a very special construction I will show when the system is completely built up - approx. end of next week.
You are right a 4way is absolutely adequate. Just for fun I have added the small amounts I have paid for the drivers only - then the other material, the work and did mulitly by 6 -which is the usual sales price of speakers- Unbelievable!

Thuchan nailed it.

"If you ever had a chance to look into the motor design of a big Studer Tape machine or at the big EMTs you know what motor design could be at its best. This is how professionals do it. Maybe we are used to deal a little to much with the consumer audio works..."

The Studer uses a proprietary 3-phase eddy current motor with an external rotor. This, as Papst would call it, is an "Aussenlaufer", or electric flywheel motor. The Studer is particularly low torque, but is very stable and quiet. Neumann used similar designs in their studio equipment, except those were significantly more powerful, but noisier. The Neumann motors are the big brothers to the ones we find in Empire and Rek-O-Kut turntables, and go a long way to explain why people continue to be enamored with those cheap vintage turntables.

EMT used a variety of motors, but all were large in comparison to most modern turntables, and some followed suite with the solutions offered by Studer and Papst.

The bottomline, in my opinion, is that many of today's makers of turntables sacrifice a bit of performance for assured motor silence and ease of construction. Many users expect the more positive aspects of their decision, but listeners of the old high performance machines don't put stethoscopes to the plinths. They tend to spend more of their time listening to music and tapping their feet.

Caveat:

Regardless of the findings of the old reputable manufacturers, (and the opinions of Thuchan and me) there are smaller, less powerful turntables that deliver music very, very well. Audio is filled with flavors, you know.

And Analog Audio is angelic and by the time we figure out completely the most elusive chain in a 2-channel audio (TT), we will be dancing in the presence of God instead of sitting down and listening.

Audpulse, I got a copy of a letter which was written to the TAS magazine stating that Vinyl is not benchmark, tubes are too noisy as records are BTW too and the only good signal you get from downloading. Hoorah - this is the new god we are dancing around - but not with me!
