If you still want to use those HD600 and are into DIY, you can buy a matched set of drivers from sennheiser and replace those old drivers. Also if you feel comfortable and have the time, do open up the headphones and check if the drivers don’t have any foreign materials on them, like hairs etc, as that kind of stuff can impact driver performance. Yes, cleaning IEMs is certainly a thing, they do get clogged as time goes by. Have my best regards and enjoy your music. 🎩

Being young doesn’t really matter as you can also damage your hearing if exposed to loud sounds, but I digress. Regarding channel imbalance. If your amplifier uses old school potentiometers channel balance is certainly a thing. So you indeed need to test that imbalance with other sources. Also I have been enjoying music since my teens and I’m now in my forties, imbalance with headphones was a pretty rare thing for me, as for IEMs besides the rare QC thing I never had that kind of problems. I know it’s a long shot but you should test your amplifier section for DC offset…most amps filter it but one is never too cautious as it can ruin gear.

Same here.

SDF - The Ethical Social Network What ‘Social Network’ means to us (a history lesson)

…To the users of the SDF Public Access UNIX System, ‘SDF Social’ is based on the concepts and principles of the early Social Networks that we have always been a part of and not the highly commercialized, for-profit and ethically questionable Social Networks of the late 1990s and 2000s.

Simply put, SDF has always been about Collaboration, Non-Commercialism, Choice and Privacy.

Choice is very important here. Anyway best of luck in your endeavour whatever it is.

Also in the IRC section there’s something about “Common sense” it’s a great read. Just saying. Best regards.

You could write 5000 words and I doubt they would change their views. Still I certainly enjoyed reading your words. Best regards.

It’s a policy of the community. You really should read sdf.org faq. Best regards.

I seriously doubt sdf.org will defederate due to political, religious or other kind of views unless some kind of danger to its users is involved, and even then I’m pretty sure we would go to ARPA votes over it. While the instance might be recent the community behind sdf.org is ancient (I say this with my utmost respect for them ) so yea, not their first rodeo or last one. If you don’t like the views of those instances feel free to block them yourself. Best regards.
