CrinEar Protocol Max

For the price, this is excellent. It’s plenty enough to to drive most headphones (works great on an Arya Unveiled plugged into my PC), and the web-based 10-band is really solid (I swap this between my PC and Mac, so being able to carry the EQ with it is great).

Bought this for a friend who is a newcomer to high quality stereo equipment. She is using it to power her Cambridge Audio Melomania P100 SEs, and says she’s never heard music sound better (even LIVE music).

I'm finding myself using this more often than my Questyle M15i and my Qudelix TT71. This is so far the best implementation of EQ for somebody in the Apple ecosystem.
