damn... i could use one...
but no money now, double damn...

the breadboard would only be used temporarily for optimization purposes. i could plug in anything and test for sonic improvement if there's any.

anyway, about the PCB, would you be able to make a multilayer PCB with those tools? that would keep things super tidy for a DIY amp.

RM200++ is not exactly what i would call cheap. i could give a few reasons why the PA2V2 could be considered as an 'overkill'. but that would get me flamed, so think i just let you guys be.
try browsing the DIY discussion on HeadWize rather than reading reviews on Head-Fi, and you will stumble upon something very similar to the design used in the Pocket Amp, and some senior members opinion on it.

I read through the forums and all of the pages, it took about two hours to read everything and I am happy that people are enjoying their PA2V2s.

----------------------------------------
After building one thousand, seven hundred and forty-nine amplifiers during the past two and a half years, there have been a few people who have not heard the amp, but shared their thoughts and criticisms.

  I am a peaceful soul and do not wish to argue with anyone. I really respect everyone's opinion and never felt that I needed defend the amps I build. Sure, the
PA2V2 is not perfect; I will be the first to admit that. However, the amp has been improving and I know it has made a lot of people very happy, including myself. If there wasn't something very special about the PA2V2 then there is no way over 1000 people would own one, nor would the amp be featured inside well respected magazines like the WholeNote and the Absolute Sound.

  Almost every day someone emails me to share their feelings about how the amp has improved their ability to enjoy music. This is something wonderful that keeps me happy inside. This is the #1 reason why I continue to build these amps.

Some notes on PA2v2:
Initially the PA2v2 to me is only a volume gain booster. Then I posted some impressions on sgheadphones.net about this finding. Some gosu there told me that things that can't see or hear doesn't mean it ain't there. It takes skills and experience in discerning sound, as in all hobbies of appreciation eg. wine, food, car, etc. Oh well, I took further listening on it and compared with AB amps. Maybe I'm not skillful enough, the step up of PA2v2 in terms of SQ isn't that great IMHO. YMMV.

The voltage is ok but the current is insufficient. The amp power source bottoms out when I have very powerful vocals blaring through the speakers and the amps clip.
