This is exactly what I like about them, affordable and collectible.But they are very cheap.
Thank for your super detailed impression! I really appreciate it. I see these peaks very often with monitors, the whole JH audio lineup have an unaturally boosted peaks at around 6k regions. Live engineers seem to rely on this peak a lots to control annoying peaks within their mixes. Thus, the peak on the EX800st is understandable although it would probably take a bit of time to get used to for me as a regular IER-M9s user.massive peak around 5.4kHz
Other than the peak, I'm totally fine with other issues as a collective item.
