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.
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.
