Hi! I'm an audiophile that's been breaking/repairing guitars and amps for over 15 years, and studied recording technology for 2 years.

In science terms, what is "warmth" if not distortion? I'm serious. Define warmth as logically as possible.

CDs have not only more dynamic range, they have more frequency range as well.

Optical lasers and microscopic nano dots are more precise than mechanical metal and vinyl. Moisture and airborne particulate can alter the tonal "flavor" of your vinyl as it effects the response of the needle on a journey through a soft vinyl valley. It will not effect a CD.

Play that vinyl 500 times, it will wear the groves and change the tone. That CD can be played non stop for 20 years and nothing will change.

I don't doubt you like it, I just doubt it's better.

THE ONLY thing that vinyl does that CDs do not do is reproduce sine wave forms. Digital mediums are chopped up into tiny square waves. But those square waves are so tiny your brain will not register them. Just like frames in a movie. Literally EVERYTHING else is more precise and more dynamic because....lasers. they do things tiny needles just can't do.

If you don't believe me, buy an oscilloscope or put a frequency spectrum analyzer on your audio signal and compare CD data with vinyl data.

Bonus point: 45s have better sound quality than 33s anyway. Slower record speeds provide less time/space for the needle to travel. That extra 12 revolutions per minute translates to more "information" etched into the vinyl that moves the needle, almost like a bit rate for digital. So I hope you are at least thinking of 45s when you talk about hi fidelity audio.

Cheers!
