Excellent review of the Pinnacle P1. Thank you! 
I'm still exploring the P1s myself and keep enjoying all different type of genres.
They do sound phenomenal with the CEntrance DAC/AMP combo.

@niron Really! The K7XX does as well - maybe I wasn't crazy when I thought they sounded somewhat similar

Yeah, you do get a feeling of over-ear headphones when you put them on

It's actually the sensitivity that makes it hard to drive not the impedance. The impedance of 50 Ohms makes places it nicely in a sweet spot for impedance. The sensitivity is 96 dB / mW which is pretty low for just about any headphone.

any budget amp suggestion?It seems like an amp help A LOT

I use the Fiio A3 with my P1's, and that amp drives the Pinnacles quite nicely. This is just a really really good IEM with which to play.

Good review, mate! Love adding to the other reviews, it helps!

probably going to get my hands on this p soon

Excellent Review, finally I found a five star to contemplate on buying.

Outstanding review,gave great input on things I rarely read in a review,like Genre selection---well done!!

First of all, I'd like to apologize for not replying. I didn't receive any emails letting me know of these comments, so I didn't see these until now.
 
@NA Blur Volume-wise, these are fine; I assumed that's where the sensitivity plays a role. However, even with plenty of volume, the sound seemed to still be lacking out of the Aune M2, which I know to be a good source. I figured that was the impedance. I could very well be wrong here though, let me know what you think.
 
@Ting Tiew Yik Great question! As I'm still looking for a portable amp myself at the moment, I haven't specifically tried the P1 with any. I would assume though that it would sound great with the Fiio E12, DACport Slim (mentioned before), and if you have a really tight budget, the Topping NX1 should work in a pinch. @ngoshawk likes it with the Fiio A3, that's worth looking into as well. And thanks for the feedback everyone!
