LOL. It's not that bad. Less ringing at 9kHz, which is a trouble spot, than HF2. If anything, there is a little bit of hardness which can be attributed to the 5kHz peak (we've all seen this before.) The extra bass does balance out the hot lower treble. But yeah, the midbass permeates everything!
FWIW, the PS500 are the true baby PS1000.
