I completely disagree with this post and actually find it somewhat amusing, however audio is subjective and is dependent on the listeners ability to listen.
I find the new GaN amplification rivals tube amps in every way and modern tube amplifiers are actually lacking in comparison. These are my subjective findings.
I also don’t believe you’ll get there with Class D amps knowing what I’ve recently found after purchasing them myself and what you’re expecting sound wise from your amp despite claims of Class D now sounding like tubes. They’re close but just don’t sound like tubes imo, particularly el34’s.
