Cayin N6ii Replaceable Audio Motherboard A01/T01/E01/E02

Very unique sound signature compared to A01. 2 of the filters soothe the "slightly-over-exphasized mids/vocal" in solaris and EE legend X, to a well-balanced degree which I am especially impressed with.
Overall I am happy with T01 paired my other earphones and headphones. Hoping to get E01 and E02 when have time.

So much more to my tastes! Better instrument separation and detail. Sounds great on HD820's!

Oh the E02 motherboard sounds so good~

I love this motherboard. I don’t have a reviewer’s level of skill, but I hear clarity, transparency, a natural and musical presentation, strength and slam in the bass, gobs of power, instrument separation, out-of-my-head sound (in front), and battery life is better than T01 which was my go-to favorite until this one. I’m using Empire Ears Legend X.

This is the second ESS AMP Module offering from Cayin for the N6ii DAP . The E02 uses 2 ESS Sabre ES9038Q2M DAC chips, while the first Amp E01 uses a single ESS Sabre E902038PRO desktop chip which is Single ended output only using a switching amplifier Class A/B and A with 3.5 PO . The E02 is Class AB Amp only and has a single balanced output 4.4 PO. Both of these Amp modules are worth buying each one has something to offer in terms of sound signature. I would highly recommend Music Tech for these purchases. I have bought the Cayin N6ii T01 and all of the amp modules ,A01,E01,E02 from them and have received excellent shipping and communication.
