Micro Seiki RY-5500 motor noise repair pdf

Dear Kip: I use Audio Technica AT-666 pneumatic footers: four in the main unit on the MS each footer and three in the PS. Works great.

A proper isolation is a must to achieve the " best " on the RX 5000.

Btw, tremendous/great job you made with those lovely Apogees, congratulations!

Regards and enjy the music.

Sorry: AT-616.

Hello Raul ..........

I have had both the AT-616 and EquaRacks on the 5000 and I would give the nod to the EquaRack, although the AT-616's are very good and clearly superior to cone type devices.

Nevertheless, experimentation to date a DIY has a compression spring base in the lead position for the most effective isolation system. I a hoping that the machina dynamica spring system will give a benchmark comparison.

I am a firm believer that effective isolation of the RX-5000 is very important as there are lots of inherent internal resonances from the chassis, platter and arm board interfaces. They must have an impact on sound - as does the wood and resins used in a violin define its tone n'est pas?

Dear Steve: Yes you are right. The Rx 5000 has no isolation and we need to take care about.

I never hear a MS 5000 on a spring isolation system but there is no reason why does not works fine.
Till today I don't know the perfect TT isolation because this subject has many interactions overall and some isolation systems are very good in some " areas " and other systems in other areas.

Yes, I know that certainly there are better isolation ways than the AT-616 but these ones works for me and I never have the opportunity to test a different one in my system.

Regards and enjoy the music.

Another quick note on RY-5500 noise: I recently received an e-mail that described a subtle "clicking" noise emanating from the RY-5500 when under various thread or belt tensions. I noticed this too from day one of ownership and thought it might be normal. When the major noise occurred and I fixed it as described in my article, I noticed this clicking also went away! I can only suspect that sound is abnormal, too. The good news is it is possible to have a completely silent RY-5500.
