I was thinking about your question and realized that headphone reviews are all about the equipment you to drive them. So, I went to see your virtual system. Surprisingly, there isn’t one. I would start there. Let’s see it and maybe a summary of how you developed it and your history. Sounds like you have heard quite a few..
I’ve used headphones extensively since the ‘80s, and particularly over the last twenty years while putting together a good headphone system. I found the sound of headphones vary greatly depending on the equipment you use to feed them. I have gone through over half a dozen carefully chosen good quality headphone amps and found that the strengths and weaknesses of different headphones can vary tremendously depending on the headamp… the amount of detail and more subtle tonal balance is strongly varies be the source / DAC. Have you found the same?
I guess if I were to try doing reviews I would want at least one high end system and a couple that are more common ones. I noticed that differences between headphones ( I have a bunch, I’m sure you do as well) that seem big with less than ideal input nearly disappear when fed a really high current natural sounding input.
Sounds like you are ideally suited skill wise I’m looking forward to hearing more about your interest in headphone systems.
