Nevermind I just read the thread on it :*( lol
Panda how do you like that Project H, would you recommend it for someone looking for something neutral as the O2?
Project-H looks really neat, looks amazing, well done.
Nevermind I just read the thread on it :*( lol
Thank you all.

This is the thread on it.
No it is not for sale, it is custom and limited edition for only 10 people in the entire world. If it was for sale, I wouldn't post it in this thread, as it would be bias and bad. I was involved in project. But it is not for sale, and there is interest so I personally chose to post the link. As it is not for sale. Just to put that out there.
It will be my main reference unit. I don't review things that are very expensive. Thus the O2 serves as a good reference amp for my reviewing. Many have it and it is reverred so its not a problem.
So yes, I would recommend it as the unit was very cheap but you can never buy it. Ours is also very modified in how the O2 works and parts that are on it or what aren't.
I am updating review info on other reviews, but I should be able to do some magic tonight with it.
I just want to say that O2 is not C5 bigger brother. O2 is developed by someone else, it is made and sold bu JDS lab. Their design philosophy might be different.
C5 is developed by JDS labs lone. So strictly speaking C5 is on its own and therefore might sound quiet different than O2.
Yes, C5 should be audibly indistinguishable from other neutral amplifiers such as O2.
Check your facts, and don't assume things without eveidence and research. Here is some direct quotes from John, on the JDS Labs C5 blog:

audionewbie I believe was saying that they are different amps and thus it will require more info, and actual listening to get down to who is the big brother of who.
His opinion was that it should sound different.
A manufactuerer's thoughts do hold weight but it should not be used as actual evidence for the performance of an amp. If we were to all do that, then Beats and Monster's new lines are thus the best headphones on the market and is in no way matchable by any others.
And then that's where reviews come in.
A review is no more creditable than a designers words. As we all know sound is subjective, and heard different to the individual. Not everyone will think it is neutral, sure. But right now, when the C5 hasn't been heard by anyone, going by what information we have is all we can speculate upon.
Not to derail the Fiip thread anymore and I do apologies I did not assume anything, O2 is design by Nwavguy, C5 by JDS lab. Two indepedant product with complete different design. If it was design by the same designer we only than call it its little brother, for all I know the O2 designer might hate the C5 let alone consider it its little brother.
Only when a company decides to revise their unit or made a new amp based on some of their older product we can call it its brother, as it stands the two products are based on different designers.
C5 began as an experiment, and even I was skeptical that we could outmatch c421′s THD+N with a digital potentiometer. Thus, we bought a dScope III and set no project deadline and no budget. We’d either continue shipping c421′s, or continue experimenting.
By January 2013, it was clear that C5 was electrically complete. We quietly put C5 PCB’s into production instead of another batch of c421′s. C5 had not only hit our THD+N goal, it had matched the O2!
...
The C5 proof of concept began as an Arduino Pro with messy wires coupled to a c421: DIY style.
I just got mine and I was hoping it would be more neutral like the O2 I just sold. Sigh, I may keep this as a portable.
Return Policy
Pre-assembled amplifiers, DACs, and unused standalone parts may be returned for refund or exchange within 14 days of shipment delivery. All returns are subject to a 15% restocking fee. Custom cases are non-refundable.
I know this is off-topic, but as was previously discussed, the C5 might be an option worth looking into if you're interested in fairly transparent amp [I'm not saying it is, but it is an improvement over their now replaced C421 amplifier, which compared favourably next to an O2].
From JDS Lab's website:
From extrapolated values, the C5 is around:
~86 mW @ 32 Ω
From manufacture measured values:
28.65 mW @ 600 Ω
74.24 mW @ 150 Ω
It doesn't supply nearly as much power as the E12, but it should more than enough to drive most headphones to a reasonable volume level.
The C5's started shipping on Friday, so stay tuned for impressions next week.
So what your trying to say is that the C5 should sound pretty neutral?
