you can buy the pcb only from jds labs, no need to GB anymore: http://www.jdslabs.com/item.php?fetchitem=O2PCB

I am quite interested in this amp, but probably going to buy a completed amp instead of building one for myself.

you use local pcb manufacturer? nicee..

So how is the progress now? What is the pricing if get from you? Plan to do a review of my own especially with some current hungry headphone. (not ortho, just dynamic driver that drain current)

Thats the thing. Way too open ended. Dont really understand the true meaning.
How much to build/ buy pimeta?

If the price of the amp falls within the amount that i have, i might consider buying it to test out. Spend too much already. Anyway how is the speed? Im in seriious need of a fast amp for my jh. What 600 ohm headphone you have tested now.

i'm interested to review this, but i'm in johor

got pimeta to compare this amp to

if i cn get it below rm 400 completed i'll just buy n do a review n keep it

ok pm me details ok thnx man n power up full size ? i mean have power for up to how many ohm? i know its kinda personal preference but just roughly cn it drive?

wow if it can give dynamics to the t1 that shows something

Leolabs Nwavguy o2 impressions/comparisons

Setup = Sansa Clip+, Hifiman re262, Soundmagic PL-30, O2 amp, Govibe Mini Box Amplifier

Clip+ and re262
>Re262 sounds thin, bass is anemic, highs are dull, mid is the only thing present. Overall, the sound presentation is like looking at the sunset through a telescope. You can hear the voice, but the rest is cut off. Notes sound like they are covered by a thicket veil.

Clip+ and Govibe MBA and re262
>MBA has V-shape sound according to some other reviews. So bass is slightly empowered but not a lot, (even my soundmagic  pl30 has more sub bass), highs are more prominent and mids have retained their position. Overall the sound is better defined. Notes are revealed by going under the blanket. But its a bit dark under the veil.

Clip+ and o2 and re262
>The sound is clean, squeaky clean. Govibe mini box has a tested THD+N of 0.008% which i consider pretty good. But the o2 has THD+N 0.0016%. I can hear the subtle differences and realize it is too clean. I like my songs a bit dirty, rugged and rough. They sound musical in their own distorted way.

Bass is sharp or tight, compared to the MBA (honestly prefer a bit of messy bass).
With o2 its like listening to your friend talk in a sound tight room, there's no fan, or fridge sound running in the background. There is no air or space between me and the vocals. It sounds like the sound is coming directly from the instruments without having any interferences.
Highs are sweet and unobtrusive. The veilis lifted and what a sterile sound it is. Everything is revealed and nothing is left hidden.

Leolabs did a good job making the amp and delivered it fast.

Build 8/10         
Looks 5/10         
Portability 5/10
Sound 10/10

Thank God these are made for the ears and not the eyes. Joking, they aren't too bad looking.
They have wings too but why can't they fly?
