i'm experiencing a love/hate situation with this. it's working tremendous with already easy to drive earphones but struggling with hungry ones (like havi & r3). definitely useless with havi & r3. do not helps bass capacity and can't even deliver enough volume without distortion. but i must say, my koss kdx200 instantly became kdx400 after pluggin into ap001 far better than e11's bass for shure. there was so much bass i couldn't believed my ears, it seems the claims were true about that. it does not just eq frequencies like the e11. i'll further investigate this later, hope i'm not mistaken.
 
note: that blue light does not go off when there's no sound at all. even if i mute the sound from windows it does not go off. when i unplug the input cord it immediately goes off, but if i unplug the other end of the cord (from the sound source) it waits like ten minutes then goes off.

Mine go off immediately after unplugging it from all the jacks. 
 
And yes... I use mine with Garage1217 Project Sunrise III to boost the bass and warmth for fun and it work great!

is it closes itself when there's no song playing but source is still on (not in sleep mode) ? i was expecting something like that since i'm using my computer with it. maybe i was expecting too much... same goes for the performance. compared to r1 + e11, what i'm experiencing right now with r3 or havi + ap001 is not even comparable. i know this is not e11 but i was expecting something better. too much distortion on high volumes and it distorts even with no frequency enhancement (by equalizer) applied. i don't know if the amp or earphones causing this but that's what i'm experiencing... it still works good with easy to drive earphones though.

I connected it to a tube once, to my iPhone, to my iDSD. Once unplugged the power switches off almost immediately.

The EMI is indeed pretty bad. I can't use it while on the go myself specially when your WhatsApp rings almost forever in 3G

here's my real world findings about the bass boost frequencies. song used is "therion - the invincible" because it is one of the songs that contains a part (between 1:41-2:01) which clearly reveal any amplification around 125hz. sound source is Audigy 2 ZS. desibel values are the maximum amounts i can tolerate without getting any distortion. tests made with koss kdx200. it's a very flat sounding earphone and ap001's 125hz amplification suited extremely well for this song & earphone combo... it also shows how much ap001 effects to the total volume on my setup. first values unamped, second values amped. differences are in bold.
 
Volume: %78, %47
31hz = +15db, +15db
63hz = +12db, +12db
125hz = +6db, 0db
250hz = +6db, +6db
 
so yes it boosts ~125hz by 6 desibels. but this is not the only side of it. it greatly enhances overall bass feeling, removing distortions and widens it. 125hz amplification sounds good with some combinations but sounds bad on others. it depends on what song you're listening and your equipment. if you didn't like it just lower it from your equalizer setting. vaziyetu reported from rize, turkey.

Just FYI for anyone that was following my wait on the AP001, I got it right before thanksgiving, just didn't have time to post about it. Also haven't had time to give it a go yet so maybe I'll have some comments for this thing by mid-week.

Just got mine..Been playing with it for about 30 minutes after charging. The Amp is quieter (less hiss) than the FIIO FUJIYAMA. The EQ is a flatter response with just a slight bass enhancement compared to the FIIO set on heavier bass settings. If you like a flatter response with just
slight bass enhancement with much less amp hiss than the FIIO then this is the unit for you. For me and my headset (Audio-Technica WS-99) and my choice of music I need the additional power of the FIIO....
 
Going on Ebay (Lower 48 U.S. Only)...SOLD!!!

Hmm.....I will have to see how this is, it seems like exactly what I'm looking for in sound signature, but I'll have to see if it's what I'm looking for power-wise. Havi B3s are pretty hungry so I'll have to see how that goes.

Good review, and what a lovely website. 

 Any chance you'll branch out and review products that are not made by Brainwavz?

He's already reviewed the B&O H6, the iFi Micro iDSD, and a lot of other stuff. Although if you're talking about future reviews, well...

I know, I was only kidding. lol I'm surprised his site hasn't turned up for me before though. It's well put together.

Nice review and blog site!
Right, EMI noise is very annoying.
