I changed the coupling caps from the stock .12uf to some .47uf Solen AGM silver sounds and the bass response is much better now. Linear down to below 16hz. Blue is before, green is after.

FYI, I bought mine in the last drop so I've only had it for a couple of months and this weekend it essentially blew up. Smoke started coming out of the unit and it stopped working completely. I'm waiting to hear from the help center here and don't know if I got a bum unit but thought I'd let people now.

I'd pay a little more for a minimum 8 watts / channel into 8Ohms ... My speakers are 89dB efficiency rated and I know I need that so as not to much the amp into distortion areas I don't want to be in. I missed the Glow Audio Amp Two .... PLEASE bring that drop back. I want to buy one at the price it was offered at previously!!!

I measured mine and can confirm the frequency response has the bass roll off focalpoint reported. People have improved bass response of the APPJ PA1502A headphone amp by changing the coupling and cathode bypass capacitors to larger ones. It looks like this amp uses almost the exact same parts, so I'm going to try the mods and see if they help. Hopefully the bass isn't just limited by the output transformers. In any case it's not a big deal if you're using a sub, you can just turn it up a little.
