Theoretical question about how CD's work

I just moved and set-up one of my video rooms. Yes, the IC to the receiver was high end as is the speaker wire (left overs from prior audio systems). Using an HDMI cable from an $85 blu-ray player, my CDs sound fantastic (in terms of tonality, dynamics, PRAT and imaging) using a Yamaha CR620 receiver and ADS 620 speakers. Also, 4 SR HFTs on the TV and front glass stand.  No, it doesn’t have the ambiance retrieval or bass slam (but goes down to probably 40Hz). I can’t believe how good it sounds (the room is also 18’ vaulted ceiling and about 48’ wide X 30’ deep). Even my wife commented on how good music sounds on it (it will take me some time to set up my audio rooms and I've just moved about 27,000 LPs/78s and 7,000 CDs-I never want to do that again).  So, a cheap ass blu-ray player can sound amazing. I have a collection of about 30 CD players like Denon, Sony, HK, Sharp, etc. from the 1980s and 1990s because I was so dissatisfied with the sound back then. Now, even a cheap player can sound miles better.  I might as well donate them and take the write-off.  Only a post 2000 DAC or high end CD player sounds better.

Exhibit A

I recently heard a friend’s (big) system that employs a clamp down device on the CD. I was able to improve the sound considerably by using my Mystery Tweak 🤫 on the CD, which stiffens and damps the CD. This, gentle readers, means the CD clamp down device is not (rpt not) effective in preventing CD vibration and flutter. Even CD Rings ⭕️ which are a good idea and address the problem I’m referring to, are not completely effective, even though they add mass to the circumference of the disc, helping reduce flutter and wobble.

That's the stupidest thing I ever heard. Cheap, flimsy optical drives jammed into laptops have no problem tracking a CD spinning it more than 50 times normal play back speed.

Don't be silly. There's a big difference between playing CD audio  in real time and pulling data off a CD on a computer. I'm pretty sure you knew that.

Actually, I don’t think he did know that. As my old boss at NASA, Chuck Rounds, used to say, hit a man when he’s down.
