No. Turntables dont sound good, they sound great. Not sure why people enjoy listening to 1s and 0s. I find it distracting. Music is analog.
And im not sure who these people are who think vinyl has a "noise." It doesn't. Unless you dont know how to take care of your records, noise, pops, hiss aren't that common. Ive listened to records for close to 60 years. Some records are that old. They still sound new. The only albums that had any issues were the ones I played without a cue lever while drunk.
There is so much wrong with your post, and we have to continue to debunk that myth you are espoising.
First off I agree LPs can and do sound very good and the surfaces are very silent. However they would not be so silent and low distortion without the use of dynamic range compression. An analog LP gives you at maximum 60 db dynamic range. If it did not the groove could not be cut, and surface noise would be intrusive. The other issue is that very deep bass has to be rolled off, otherwise you would have poor side length and few if any cartridges would track the groove.
I have a very large collection of LPs going back to 1954 when I was seven years old. I own four very good turntables all vintage, well cared for, properly set up and maintained. I enjoy my vinyl collection still, but I don't pretend it is as good a modern digital technology.
The fact the the digital system is binary, does not mean the music is and far from it. In any event when you listen to your vintage AR turntable via your digital receiver, you are listening to digital audio. That receiver you list converts analog audio to digital and back to analog just so you can use your digital volume control on your receiver.
This video explains why this 1-0 staircase nonsense is just that.
Your turntable is iconic due to its age, and introduced many to reasonable quality disc reproduction, but was always a budget turntable, but it has significant shortcomings. For one thing it has no anti skate compensation, and the arm is relatively crude in design. If you really want to enjoy vinyl at its best then an turntable upgrade would definitely achieve that. There are new and vintage options. Three of my turntables are older than your AR.
These turntables date from the sixties and turntables were sold without PU arms and plinths. They have had some different arms over the years.
This is my newest turntable, that I bought non working and restored it and found and SME series III arm for it.
