Speaking of RSA variants, he paints over the opamps with red paint as well. I would take a pic of the innards, but they all came out blurry because my camera doesn't have a macro mode

The amp works great and it's sound is rather aggressive unlike the GV5 that I heard before which gave a more relax sound. For me, the amp sound much louder as DAC and in that mode it can run my 250ohm DT990 loud enough but I don't like how it sounded that way. By the way, the info about the amp's earphone impedance range of 16 to 120 ohms mentioned earlier in this thread was printed on the amp's manual/instruction sheet. Only minor thing is that it's so small that I can't use the interconnects with big plugs like Canare F12. Great that I also got matching ICs from Jaben which fits the size and which synergises well with the amp.
But hey, it works great for all my other cans, and it's so small and nice! The DAC works like a charm with both my PC and my notebook PC, just plug and play away my library of MP3s. And the battery life is great, and no problems even when out of juice/dead cos it uses AA batteries which is rather easy to buy, whether alkalines or rechargeables..
It's one of my best buy to date. No regrets. I call it my "poor man's" tomahawk, with DAC somemore, so MUST buy! My unit happens to be the display/demo set in the first batch, becos I just can't wait then. LOL.
