What in your mind represents real technological advancement.


To be a real advancement the technology must improve the sound quality. Just extending the bass or the high end can't be call an advancement if it doesn't sound better. If the bass goes " lower " but is muddy or the highs go higher but are " bright and forward and irritating " then that does not improve the listening experience. So the question is what improvements make a speaker more enjoyable to listen to.

Hey guys, we can't forget to take our meds. they are said to reduce those symptoms....
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.
