If you want to miss out that's your business. The artifacts you mention are easily solvable or have their digital equivalents that affect SQ far more adversely.
Let's analyse.
countless electrical, mechanical steps GENERALISATION. NO MORE STEPS THAN DIGITAL
chemical steps WHY SHOULD THE MANUFACTURE OF THE DISCS AFFECT SOUND?
audio compression NONE. COMPRESSION IS A DIGITAL ARTIFACT
RIAA compression to limit the bass groove amplitude IT IS NOT COMPRESSION IT IS ATTENUATION AT ONE END AND AMPLIFICATION AT THE OTHER. EFFECTIVELY MERELY THE APPLICATION OF A POTENTIOMETER LIKE THE ONES ON YOUR AMP
cutting of the master disk IT OCCURS IN REAL TIME AND REPRODUCES THE SIGNAL AS A CURVE, NOT A SERIES OF DISCRETE STEPS AS IN DIGITAL. IT OCCURS IN REAL TIME AND HAS NO CLOCK ERROR OR DITHER THAT ARE THE INCURABLE CONCEPTUAL SCOURGE OF DIGITAL
the wear of the master disk THERE IS VERY LITTLE WEAR. IN MOST APPLICATIONS IT WILL MOTHER AROUND TEN STAMPERS ONLY. THE DAYS OF ELVIS AND THE BEATLES SELLING MILLIONS OF COPIES ARE LONG GONE.
the chemical and heat treatment steps with pressing the disks DEALT WITH ABOVE. IT'S JUST PART OF THE MANUFACTURING PROCESS
the wear of the vinyl, the dust and (micro) scratches ON 99% OF MY DISCS THESE ARE INAUDIBLE. BY THE WAY, IT'S BEST NOT TO EAT OFF YOUR LPS
the shape of the needle SO WHAT??? THE LINE CONTACT PROFILES OF GOOD MC STYLI READ EVEN MORE ACCURATELY THAN THE ORIGINAL SPHERICAL TIPS
player rotation speed error IS ALMOST NON-EXISTENT AND FAR LESS OF A PROBLEM THAN CLOCK ERRORS AND DITHER ON DIGITAL
disk non flatness and non centeredness WHERE THE ERROR IS BIG THIS IS NOT ACCEPTABLE PRODUCT. THERE AREN'T MANY OFTHEM BUT RETURN OR DISCARD WHEN YOU GET ONE. SMALL AMPLITUDE WARPS OR CENTREING ERRORS ARE INAUDIBLE. THE VERY SHORT LIGHTWEIGHT ARM ON MY AEROARM PARALLEL TRACKER WILL RIDE ALMOST ALL WARPS
arm angle and weight correction JUST SET IT UP CORRECTLY, FOOL
wow, flutter ALMOST NON EXISTENT THESE DAYS AND FAR LESS OF A PROBLEM THAT CLOCK ERROR. INCIDENTALLY THIS IS JUST REPETITION OF ROTATIONAL SPEED ERROR, ABOVE
rumble NON EXISTENT THESE DAYS
translating mechanical movement into a tiny delicate electrical signal HAS BEEN PERFECTED
problem of stereo separation WHAT PROBLEM? 30DB IS PLENTY. IT ACTUALLY REPRESENTS THE LATERAL BLEED OF THE SOUND IN A LIVE SETTING FAR BETTER THAN THE BRICK WALL 90DB SEPARATION IN DIGITAL. STEREO IS ONLY AN APPROXIMATE ALGORITHM OF THE LIVE EVENT WHICH CERTAINLY DOES NOT PRESENT ITSELF AS TWO SEPARATE SIGNALS WITH NO BLEED. IT CAN BE ARGUED THAT MORE CHANNEL SEPARATION GIVE A POORER REPRODUCTION OF THE LIVE EVENT
the need for great amplification I THINK WE'VE PERFECTED AMPLIFIERS BY NOW
introduced noise floor WHAT IS THAT? ALL SOUND REPRODUCTION SYSTEMS HAVE NOISE FLOORS
reversed RIAA correction . SEE ABOVE. THIS IS MERELY THE REVERSAL OF THE ATTENUATION AND AMPLIFICATION PREVIOUSLY APPLIED.
