  Hi guys bit confused here I ordered the o2/odac rev b combo and there is no usb port for the cable it came with, am I right in saying I have been sent only the amplifier?

Try to search it on the backpanel.

There is nothing on the back so I am guessing I got sent only the amp?

I think it's pretty clear. Have you tried contacting JDS yet?

Yeah.

99% there is no ODAC inside. Its USB socket exdends beyond the panel.

There should be a usb port on the back of the unit.  If there is no usb port, then there is either no odac.... or they accidentally installed a rear plate with no cutout for the usb port.

inputs are so 2014.

The image does appear to be an O2, rather than O2+ODAC. It does not appear to be a JDS assembly.

That unit is an Epiphany Acoustics Model and not JDS Labs, and it is definitely the amp only model as it says EHP-O2. Their O2/ODAC model is called EHP-O2Di I believe.

Yes, I agree. I own the EHP O2-Di (O2/ODAC) with the original ODAC and on the front panel, there is a cursive 'EHP-O2Di'. According to the imgur picture, it is definitely the O2.
 
In that case, I'd try to contact Oliver from Epiphany Acoustics by going to Contact on Epiphany Acoustics' website:

(or drop his Headfi acc a message?) 
 
Cheers. I've been using the EHP-O2Di without problems to power anything from ER4s to DT 990, 600 Ohm and it drives them effortlessly!

Hi what is his username on here because I am not getting any response through email?

I think it's this one: http://www.head-fi.org/u/277285/epiphany-oliver
 
I just browsed the O2 forums and found it.

I'm thinking about getting the O2 as an amp for my aune t1 as I just got myself a pair of alpha primes that is measured at 47 ohm I think it was. And in the alpha prime thread people talk about them liking a good amp.

So my question is What would be the optimal gain selection be ? The standard 2,5x-6,5x ?

When the volume control on my ODAC/O2 combo is very low (And I mean extremely low, maybe the first couple centimeters or so) most of the sound only comes out of the right speaker. Anyone know if this is normal?

Perfectly normal for pretty much all amps of this price range actually. This is an issue with all potentiators in general unless you go with amps with stepped attenuators, which have perfect volume matching throughout.
