Machina Dynamica New Dark Matter CD and Blu Ray tray treatment?

mahgister All this thread is interesting... I cannot try the NDM,because I dont use now a cd player... I had transfer all my cd in flac files et listen only to flac files...I keep the noise of the computer to reasonable level and the results are at my satisfaction... But all that is because on the many tweaks I implemented...

>>>>One can’t help wondering, wouldn’t you have gotten better results if you had used NDM in your player when you transferred all your CDs to flac files? You would now be listening to music with better signal to noise ratio, no?

Red-IR and violet-UV absorptive dyes are interesting, too. And these dyes have been around like forever. My last product was a dye. There are many ways to skin a cat. The whole point is to skin it. Otherwise, it’s just a lot of talk.

There’s no substitute for signal to noise ratio. - old audiophile axiom

I speculate one reason why a lot folks gave up on CD and moved to streaming or whatever is that they couldn’t get it right and gave up in frustration, that is if they even tried. Or they like the convenience or whatever of streaming or serving or whatever. I understand that. Untreated CDs played on untreated CD players generally sound thin, bland, compressed, metallic, wiry, irritating, remote, plastic, synthetic, two-dimensional, gloopy, generic, thumpy, hard, sour, rolled off, screechy and like paper mache. I’m not trying to set the world on fire. I just want to start a flame in a few hearts.

GeoffKait you are right for the cd untreated.... I dont doubt that....This is the reason that I am interested in this thread.... I will install in the year to come a cd player for sure … I will try your NDM then....But for lowering the noise level I had my own stones and crystals connected grid on the computer and cables and gear and electrical house cables grid,hence "all is quiet on the western front"...

I understand where you’re coming from but when I say signal to noise ratio I’m referring to the optical SNR and the downstream analog SNR which depends on it. By reducing background stray light in the CD transport you increase optical SNR.

Of course, as you say, all sources of noise and distortion in the system should be controlled and minimized, too. The claimed SNR of 90 dB for CDs is achievable only if the system can handle it which, obviously, in most cases it can’t. That’s why the humble LP or cassette oft sound more dynamic than CD. As for the claimed Dynamic Range of 90 dB, many CDs are overly compressed so there goes your dynamic range spec down the tubes!
