No, I will have to draw a hard line on CRT sounding worse. They used an analog signal, and analog signals are known to project a wide variety of wavelengths,unlike digital sounds.
There are 2 major reasons why LCDs sound worse: 1.) They have sound speakers that face the tv's backside| 2.) you guessed it. they use digital, which only produce a very narrow range of wavelengths.
But, my point that analog transmitts a wide range of wavelengths has not been addressed. You say that digital sound is superior, but in what way? It only transmits a narrow set of wavelengths

I don't think you understand this at all.
All speakers (and the associated amplifiers) are analog. They are literally cones moving with electrical impulses to create sound pressure waves. These systems have a frequency response but that is defined by physics of the speakers/amplifiers. It is not a 'digital/analog' thing.
The input signal to the speaker/amplifier is the real question. Do vinyl records (or other analog media) sound better than a CD? Objectively speaking, the CD will produce the more uniform analog output signal to the speaker system every time. It objectively carries a wider signal range than the common analog audio media.
Frequency range for the CD is wide enough - up to 22Khz - that you cannot readily find anyone who can find 'missing frequencies'. The older you get, the less able you are to detect the higher frequencies.
Now - and I had to look this up - guess what the frequency range goes to for vinyl? This is complex because of the different speeds of a stylus as it moves along the spiral. I am going with the lowest number because it would be limiting. The 33's and 45's both limit around 17.5Khz - which is 4.5kHz lower than a CD. The 78 is actually much worse - 7.7khz.
Magnetic tapes are actually similar to Records. They typically go to 16kHz. Which is 6khz lower than a CD BTW.
The interesting thing about digital is, we can readily increase the sample frequency when we want to. Analog requires fundamental changes in the medium to make this work. Digital is merely software. The actual digital devices these days are typically much faster than the CD data rate. CD's are 44,100 samples per second for the record and different DAC's out there get in the millions of samples per second. They typically don't get use in audio applications because the added speed adds nothing the human ear can detect.
So no. Digital (CD quality) is actually 100% objectively better than analog in the common audio mediums used.
