I wish someone would sell a portable amp like this one that would put out at least 850mW in class a and a bass boost like the Fiio E12 but again in class A.

Thank you, even though I wanted a 100% Class A, I may try it and return it if the sound is the same as my E12.

It’s not the same. Reviews say it’s more like amplified E12A. It uses different processing chips for amplification.

This seems like a nice price for the product compared to $109.99 + $9.95 shipping (B076J297SG), but appears to offer less all round than the comparably priced and similarly designed non-discounted $99.99 FiiO Q1 Mark II (B0757MH46M). The numbers do seem better than the $69.99 FiiO Q1 (B0157DKAU4) for substantially the same features.
Prices and product codes are based on current Amazon listings and I own and enjoy a FiiO Q1 for which I paid $53.99.

I have the Fiio Q1 aswell, sweet baby jesus! It's so good.
I would definitly recommend the Q1 as well over this, as it has a built-in DAC aswell.

If your iphone has 3.5mm jack, then yes.

I wish they dropped the NX4 DSD with its lower distortion numbers instead of the NX5.

Can this be used while charging?

Wow, unbelievable. Thanks for the report sir. If you don't mind a question; do you suppose a "usb power conditioner" may help escape this noise by-product of the charging operation? Also, do you suspect that changing a charging source, like to a Samsung phone charger; might alleviate this condition?

Hey caiz, unfortunately I've never used usb power conditioner so I wouldn't be able to answer that question. It might be worth a try, surprisingly this amp holds a lot of battery power so I dont really find myself using it while charging. I must say it powers my Hd 58X wonderfully

Any recommendations to pair this with Senn Jubilee 58X for general listening?

Yes they do, i had my eye on it for some time now. But that is a desktop version. Maybe it will work with the Nuforce DAC 3 hooked up to my PC?

I recommend it! My current portable set up goes as follows: HD58X > NX5 > AKJR > NIRVANA
