What in your mind represents real technological advancement.

It would in reality be physically impossible for the laser servo mechanism to keep up with the deviations of the laser from the nanoscale data spiral given (1) the extremely small width of the data track and (2) the lightspeed of the laser signal and (3) the extremely high speed of the CD rotation rpm. If you were able to view the spinning CD you would see it’s wobbling and fluttered like crazy. It doesn’t take a brain surgeon to figure out the servo mechanism is too slow to be able to correct the dynamic motion of the CD. It’s like trying to ride a bull like Bodacious or Widow-maker. 🐂

The laser servo and Reed Solomon Error Correction codes are two of the biggest scams ever perpetrated on a gullible naive and unskeptical public.

Clearthink...you left out "are there" from my post. It's a fact that many "feel" better after burning cash for silly tweaks, which seems like all anyone needs to know about most of them.

Your subversive anti-fuse "rant" for lack of a better word,  has really set me off. Fuses are one of the most important "links" to more realistic audio, invented by none other then William Bickford in 1831, a land mark year to celebrate audio....you have blown my fuse and that is not easy to do......it is a slow blow 20 amp, recently upgraded with audiophile circuits. 
If you have any respect for William Bickford please retract your inflammatory  and not totally accurate review. 
Thank you in advance......not prematurely I am sure. 

Subversive...yeah man! I'd like to hear comments from others on this thread as to why they DON'T embrace the hyperbolic Magic Tweak "rants" for lack of a better word...wait, here's a better word: Rodomontade...(what's another word for "thesaurus?") Plenty of things you tweak yer gear heap with actually do work and the more secure and rational designers are generally happy to explain why, but the rise of the salesman driven world of the "I don't care how my $500 magnetic place mat works, it just does" Faith Based fan should rankle anyone who respects at least a modicum of logic. People have actually claimed that a fuse mounted backwards makes their system sound "out of phase." No, it doesn't, it never could, and to claim it does tosses credibility out the window. Subversive? Only to those with the fertile (and often fertilized) imagination of the easily misled who crave a cult that warmly invites them to drop their scruples and join in...with a 30 day return policy.
