Hi all. I have finally gotten around to building up the O2. It seems to work! sounds really nice.
I have one question, and I apologize if we've already been though this a hundred times. I used a "shared BOM" at Mouser, and for Q1 there was a 60V mosfet, for Q2 it was a 200V part. I didn't notice until I unpacked the box. Everything gonna be alright here?
Thanks all.

You are fine. The Mosfets were sourced as per Nwavguy by whatever is available that is price effective. The 200V part just happens to be the cheaper 200V part in stock to my memory. The 60V part has a 200V part counterpart, but the 60V is cheaper. This makes no difference whatever due to the way these Mosfets are actually used (although if you want to substitute, read Nwavguy's post on the requirements on these Mosfets). I see you already built your O2, so this point is moot, but anyway...
Although as a caution, be VERY careful about these Mosfets when you handle them, install them in the order Nwavguy suggested (with the board populated with other components first, to discharge possible electrostatic charges), and pay attention to the ESD handling of Mosfets. I used insulated tweezers (or tweezers with electrical tape) and a grounded soldering iron to install them. Just in case... But you have already built yours, so this probably doesn't apply to you either...

Maxx_Power, thanks kindly for your response. I figured the 200v part was probably over-spec'ed, and cheap and convenient.
Yes it is already stuffed and functioning but needs some kind of case. I like what I'm hearing, it's amazing that it was so cheap to put together. I'm probably going to need to get some better headphones with all the money I saved, hehehe.

I've ordered the O2 from Epiphany Acoustics last year and I couldn't have been happier, very clean build and nicely finished (great looking frontplate), delivery was fast (I bought before Christmas) and it came well packaged, Epiphany is a quality outfit.
Hope that helps.
I am really late to this thread and the group buy is long gone, but if someone has a spare PCB laying around, I'd be glad to buy it.
Tnx.
I think I have one.
