FLO's journey with the Micro Seiki RX-1500

[Florian E.]

Fully agree, and done right you will get significant improvement.
That's why I recomend these.

Hi Tony,

Absolutely, I see your point. However, I believe it’s important to note that a universal recommendation isn’t always possible in this case. Every setup is different, and factors like external resonance management and the overall system need to be considered to achieve the best results.

Simply saying that rigid feet are better than damped feet isn’t always the way.

Best regards,
Florian

Nothing simple about me I'm afraid ...
Just recommending R15 feet.

Enjoy your RX-1500VG, it's a very nice turntable.

Congrats!!

The Micro Seiki are amazing tables!

yes, that's where we differ, the air bladder feet msb 100 were developed for smaller series by micro seiki because the large air bladder base ba 600 was too expensive. I don't have to convince anyone, just try it out and judge for yourself.

I have a friend with that BA600 large air bladder base for his mint SX 8000II. He listens with the bladder deflated. I had that table and placed it on 2" thick steel plates on a good rack. I lived with Vibraplane pneumatic platforms for years.

This was my best buy in my hifi history I don't want to say more about it In the german analog forum there is a 200 page long thread about this.

both my Micro Seiki DD-1500 and my Melco are placed with solid feet on a custom 30mm thick MDF base, which again is placed upon 4 feet of Rubloc Trisolator

very effective combo
guess Florian noticed in ETF Baarlo

Sorry for jumping in ..

My rx-5000 air placed on Quadraspire bamboo stand.

My concern that too much isolation could somehow absorve all the resonance and dampen the sound,
Like placing tube amps on springy / floaty isolation.. like too much of a good thing can be a bad thing.
What i mean,
that some of the resonance energy could disperse through hard surfaces more efficiently..

Like a resonance feedback loop,
were the energy have no where to go but the chassis it self.

I'll tell you about the principle of operation. Firstly, the record player is not on a damping element but directly connected to slate plate. This creates excellent dynamics and hardly any influence on tonality. Only then do the air springs come under the slate and block everything above 3.5hz. You can lower the pickup, turn the motor off and turn the volume up to the maximum. Then jump as high as you can into the air and when you land you won't hear any sound or membrane movement from your speaker. Functional test passed

Hi @DasguteOhr

Thank you for the explanation.

Could you please elaborate more on the isolation you use,
and where exactly can i get one or similar to it and what are those pistons underneath it?

I use air spring elements from cplusw, Germany. Model SLM1A, max. load 45kg. The air hoses are from Festo, I have to warm them up a bit so that they fit on the connections. I also sealed them with 2k glue.

A slate plate with the dimensions 70cmx55cm and thickness of 5.5cm weight ~65kg. with my tonearm bases and the td 124 that results in 110kg mass. we have tried almost materials, slate is really the best from a sound point of view. a few photos from well-known.

P.S
Air must be refilled every four to six weeks. This is the only known disadvantage. You should buy a good bicycle pump.
P.P.S
Since the company had to produce so much for us, they now have a table in the program

I have 8 of those from the days I had Wilson Watt Puppy on them
mine were bought at RS Components
thought of using them under Melco, but then I tested Rubloc Trisolator

@DasguteOhr:

that's a very sophisticated air spring decoupling system for your TD124 turntable and I do see the advantages.
Would work for my TT as well and I might try it.

And then I had the suggested MSB-100 feet on my late BL-91 which I used between 1980 and 2005.
Due to uneven weight distribution of the plinth, two of them suffered and lost presure, causing for a tilt.
The BL-91 is at about 20kg, my current RX-1500 incarnation is over 30kg (including motor unit over 40kg).
You can imagine what would happen to these MSB-100 feet - made me react with a HaHa smiley.
No offence intended.

Best regards, Tony

The msb-100 were designed in 1974, long before the need for beefier feet, I mean long as the changes were happening quite fast at that time.

Beside, Micro at the time was supplying lot of parts in case they were to fail for the japanese market. Not so much elsewhere as it was far from being major markets.

As for the RX-5000, yes, it can become a nightmare with resonances, the 1500 is less subject to this.

Micro started the larger series requiring beefier feet in 1979 for public market when they puted back the belt turntables in the shop.

No problem, I've been told that there are people who use more then four of them under one base and they are lucky with the sound of the feets. One foot can carry 8kg.
