With a focus on downsizing and having moved to Class D several years back, I have no practical interest in large heavy power guzzling amps anymore. That’s just me. To each their own. Especially when it comes to what look and sound happens to float one’s boat.
The other recent gamechanger for me is applying DSP for room correction, sound tweaking to personal preference, etc. I easily enjoy a lot of gear much more than I would be able to do otherwise were it not for DSP done well.
Practically, I am mostly off the equipment merry go round at this point. I still like trying new things, but it's now more because I just want to rather than that I need to.
