Sure. The display is always off so you don't know what the sample rate, volume or settings are as far as gain. Yes there is a light show as far as volume but I will be damned if I going to memorize those colors. And even if I did, they are nowhere near as good as a dB level on an always on display.
Yes, you can hit a key on the remote to wake up the display for a short period but doing so changes that value! You can't just wake it up to know the current setings.
Why is there no menu button on the remote?
Why is it that there is poor key debounce on the remote causing it to go two steps instead of one?
If the filter is the star, why isn't a fast way to cycle through them on the remote or front panel?
Why should I have to wait 15 seconds every time I change modes? It is not my problem that they have to screw around with their supercaps to allow this to function instantly.
Why does it look so ugly and hodgepodge? A dot matrix green LED? What is that doing there? Why is there a crease in the cover that makes it near impossible to read?
Try even reading the manual. It is faded gray over gray. Why oh why?

All this could be cleaned up with a modicum of usability testing.
