Default SONY SCD-1 Stabilizer Help

Hi,
Not found any old thread about this tuning, so I post this.
Wonder IF I could use without problems a larger disc stabilizer than the original supply on the SCD-1?? as this Sony models on the image below.
The original SCD-1 Stab weight 105 grams.
Anyone ever tried this tweak??
Someone know how much RPM a SACD disc spin in the Sony SCD-1?? Do it is the same RPM than the redBookCD??
I Thanks for any tip or direction,
Gustavo

SACD spins faster than CD (around 4 times) to accomodate the higher data rate coming off the disc.

Adding extra weight shouldn't be an issue as long as the dynamic balance of the whole assembly is correct. Once spinning the energy required to maintain momentum is very small, the extra weight acting like a larger flywheel.

Are you sure about that? The physical format is DVD, with added watermarking for security. The bit density is a lot higher on DVD vs CD so you may not need higher RPM.

Thankyou boys for your input I appreciated it.
I was unaware SACD spin so fast, I read in 1985 CD spin at 200-500rpm, so SACD can reach 2000rpm.
I intend use a disc ''clamp'' around the same weight than the original brass SCD-1.
I wonder if these others Sony ''clamps'' are aluminium or brass??
Even better would know the weight of these ''clamps''??

There are 3 SACD variants. Dual Layer, Single Layer and Hybrid. Also some machines spin them even faster than needed to "look ahead" and try to correct data errors, a bit like cheapo portables that have the "jogging" feature and have around 20 seconds or more of data in memory if needed.

Check if the sliding cover can be closed with the new clamp.

Hi,
Well remembered Thanks for it. The spece between stabilizer and the top loading door is very small with the original stab.
Here Tico-Tico is a beautiful bird name.
Best regards, Gustavo

Hi boys,
Reporting no improvement in sound quality with a larger disc stabilizer, Uh...
The small original disc stabilizer are recommended.
Regards, Gustavo

Would anyone happen to have the stabilizer "puck" for the Sony model CDP XA 20 ES that they could live without? I could really use one. Thank you. You can reply to me directly at dalehimself@yahoo.com
