Tweak Reviews From Soundstage

Two tweaks, Symposium Rollerblocks and Walker HDL, are briefly reviewed by Srajan Ebaen in the newest soundstage.com, who seems to be credible reviewer.

He previously reviewed Aurios MIB and was very impressed, he now prefers Rollerblocks (RBs). I have tried both and found the MIBs slightly preferable, however both provide similar sonic benefits being very effective under CDP. Author notes that RBs are easier to set-up, he understates the problem that heavy/stiff ICs and AC cords make to properly set-up bearing isolation devices, this is the one serious problem that some audiophiles will face. The Tungsten balls, $75 for three, is a worthwile upgrade as is the very important drop of teflon/silicon oil tweak mentioned in RB set-up instructions (author fails to mention this).

The current Listener mag has better in depth review of these, also for a "taste" of what these can do for $99 try
the Daruma II.

Another endorsement of Walker HDL, which was also positively reviewed in Listener current issue, has me
thinking I should give these a try. If you bi-wire becomes very expensive as you need 2 sets, Other members have told me they have similar good results using them.

Comments from users of either tweak?
