Did you do a DBBT (Double Ball Bearing Test ) ?
BTW I ditched my 3,000 speaker cable for anti cable, never looked
back.
Looks like it should be a winner, SS. Good thinking.
Yeah, I've read of people ditching $4,000 Nordost speaker cables for Anti-Cables and never looking back, either. Goes to show that you can get high-end performance and functionality without paying for the audiophile-grade profit margins that many high-end vendors charge.
Sorry to tell you, Stephen, but the profit margins on cables are about the same as profit margins on other gear.
Yeah, I knew that....
Wait 'til I post about the music server system I heard Sat. that could be put together for a very reasonable amount of money; way, way less than a $60,000 CD player. And it would take advantages of some of the principles developed by Altschuler of TRIZ in that it would remove the harmful effect of a "tool" acting on an "object" by removing the tool itself. More on that later...
I'll watch for it. Removing the "tool" seems to be a promising new way to think about source material.
Unfortunately, the present day economy has forced me to consider "way less money" to be about no more than $50. Think they can manage that?
Interesting guy.
I'm trying to think of the manufacturer, but there is a CD/digital player whose manufacturer thought along the same lines.
With all the computing power we have access to, it should predict for some great and cheap innovation with regard to the ills of CD/digital playback!
Stephen-
Have you thought about ceramic ball bearings? That's what Finite Elemente is using in similar products and unlike many other tweak companies they've done the research and provide numbers to back it up.
Yes, certainly, but they would be wasted expense on three plastic furniture cups. If I had a serious, extremely smooth and finished concave bearing race like that used in Symposium's Roller Blocks, that would be a desirable way to go. But a carbide steel ball bearing would be fine when used with these plastic furniture cups.
Per Jan's gentle prodding, today I went out and bought three large glass marbles to replace the wooden balls in my home-made roller bearing system.
As you might expect, the glass marbles make much better ball bearings that imperfect wooden balls, so the table is now much easier to move with respect to the application of a horizontal side-force, so it should now function better in isolation of rotational and horizontal seismic resonances.
The table now moves much like a suspended platform-type in the horizontal direction.
Sounds great, too.
Always good to see someone who appreciates the rotational seismic forces as well as those in horizontal plane. I find the vertical piece to be quite important as well.
That's why I am using Jan's squash ball/Quik-Cap design under the maple board that the roller blocks/TT rests on.
Can you describe the 'difference' you heard from your Rega?
I may try this with my MMF-7.
& thanks for the tip, nice!
Improved clarity, definition, air...all the stuff one usually gets when isolating the TT better.
