RCA Victor is the budget RCA label. RCA IN LIVING STEREO recordings are the only good RCA recordings, which are mostly late 1950’s and very early 1960’s, as in the early 1960’s RCA went budget with their pressings, and used poor quality materials and engineering. You can try buying Japanese RCA pressings of the later recordings, which are quite a bit better.
RCA Victor records' quality
I just bought three old records, I guess all the way from the mid and late 1950s. They each sound very harsh and "shrieky". I wonder if it's the way they were meant to sound? The records themselves are in great shape.
Should I rely on tone controls or is it how music was produced and published back then? Namely Elvis' first few albums?
