But they don't necessarily perform better. The manufacturer's rated frequency response is larger. That doesn't mean anything. Headroom measured a lower THD which is an important aspect of performance, but may be an audible improvement as well.
You're welcome to like what you want. A headphone this colored is not "professional" though. It's for casual or audiophile listening. For a professional headphone, you would usually want one that conforms to a field equalization to mimic the sound of speakers and live music.
PM me your next response if you have one, so we don't derail this thread any further.
I've heard both the gs1000i and the ps1000 for an hour each.
the differences are very minor but they exist.. the gs1000i is definitely more relaxing, less harsh. the ps1000 is more forward, clearer and more detailed.
I don't know if it's due to the more "forward" sound but the gs1000i had a deeper and wider soundstage. It seemed more laid back compared to the ps1000
