Sound quality has always been very important to me. I was interested in Hi Fi before becoming interested in making music myself (and I have spent a lot more money on my Hi Fi components).
I buy a synth because I like how it sounds, plus whatever other feature it has that I want. I couldn’t care less if it is digital or analogue.
Analogue synths do not have better “sound quality” than digital synths, although they may sound different.
In a blind test comparing 10 sounds, 5 analogue and 5 digital, I would be surprised if anyone could correctly identify the analogues from the digitals. It would also be very easy to use voices in the test such that people consistently incorrectly identified the digital sounds as the analogue sounds.
I have VSTs that, to my ears, sound “more analogue” than my A4.
I think people should use just their ears to judge sounds and ignore price, looks, method of sound generation and pre-conceptions. But I appreciate that is easier said than done.
