Nope digital out via windows will not let you controll bass or treble it just outputs what you feed it, you can use the EQ in programs but i always find that it makes everything sound like sh!t
To be honest i have no clue on the curves of that Indeed thing, its an ebay hybrid tube amp (tube preamp) changes some fets and caps on it and rolled some tubes, it sounded pretty good with my Sennheiser, but the O2 definitely has a LOT more details.

The only thing that comes to my mind otherwise about bass response is Damping Factor - I don't know anything about how this relates to headphone amps, so I've taken this over to the main thread at http://www.diyaudio.com/forums/head...eadphone-amp-diy-project-219.html#post2932851 to get some input from more people.
@gumleguf - sorry you've had a problem with your kit build, never a good idea to work on electronics assembly when tired, that's the way silly mistakes, like putting components in the wrong way round, happen. I hope that you can sort it out once you've had a rest.
Did you follow the testing instructions before fitting the chips? Did you cut the socket pin as recommended? Have you thoroughly checked the board for bridged connections?
If not, remove all 4 ICs and follow the testing instructions from the beginning. Other than that, there's lots of faultfinding info on the main project thread, you aren't the first to have a problem. Good luck in getting it sorted soon.

No problem. I'll look more into it when time permits.
Didn't follow the testing instructions, no. It's the first time I have problems with a kit. I took a chance and powered it on, but something is definitely not correct. I'll go backwards and run the tests as described by NWAVGUY, look for bridged connections, etc.
Update will follow later on...

Well, following the instructions seemed to do the trick:
That was an easy fix.
I'm using the default gain setting of 2.5X and 6X. It's not playing very loud even with sensitive IEM's. It's not much loader than my iPod would normally be capable of.
Using it with my Beyerdynamic DT770 600 ohm headphones is hopeless. Not enough power/volume at all, but that's ok. It's not why I built the O2.

Good news - and a good reason to read the assembly instructions before starting the build....
Since you have the full set of gain resistors, you have all you need to boost the gain - all the necessary detail is in Nwavguy's blog. IIRC, the gain can go to at least 10x.
The other thing to look at is the level of the source, obviously the greater the input level, the higher the output. The O2 seems capable of accepting quite a high input level before clipping, and turning up the source level is the easiest way to push up the overall gain.
Anyhow, glad to hear you got it working OK!
I know, but there is just so much info on the O2 kit and it seems to be spread out on so many different web sites and forums. But, no excuse for not reading through nwavguy's detailed instructions obviously.
I'm using the same iPod for input right now. Will switch to my RockBox'ed Sansa Clipx tomorrow at work and use my newly purchased Create AURVANA Live! headphones. They are pretty amazing considering the price.

@gumleguf - looks very nice - although I should point out that the front panel isn't from my kit!
How are you finding the Creative headphones?
Update - last 2 complete kits are reserved pending payment.
The remaining 2 kits are awaiting cases, looks like the cases will be delayed for a while, so if you're interested in getting a kit now, either with no case or to have the case sent on when it arrives, PM me.

Correct, yes, sorry. Front panel is *NOT* from greenalien's kit.
Those headphones are excellent for the price! Perfect for a cheap office setup. I paid around 45 EURO for the Clip+ and also 45 EURO for the headphones. Here is a review of the headphones: Creative Aurvana Live! A Classic Reincarnate | InnerFidelity
Apparently they are the same as the old Denon AH-D1001, only a little bit better.
