I was fortunate enough to get the Pinnacle PX! However, I now have a dilemma of sorts. Either my phone and my X-99A motherboard cant handle these, or the bass on these is very subdued. I can still tell that its there, but the mids and highs have far more presence. This was me "sampling" hi-fi audio, I fully expected the P2's, never bothered looking at the specs for the PX's/P1's.
Edit: I have a pair of AKG M220 Pro's that I use daily, and they have a higher impedance, get louder, have more present bass. I guess the PX's just have subdued bass? This is all very new to me, not sure how to troubleshoot/check these things beyond swapping devices around.
