The responses proceeding my post prove my point. Progress assumes advancement from a lesser point to a better one.
By most technical aspects audio equipment has and continues to progress.
Preferring vintage gear is completely subjective. It doesn’t indicate a lack of progression within the space, it just means that it’s sound is more pleasing to certain individuals.
@theaudioamp Thank you for repeating what I said; just in long-winded form. Most audiophiles don’t care about the technical aspects, they want what sounds enjoyable to them. It’s not a lack of knowledge; it’s a choice.
