There are "minions' on both sides.....so lets stop with that and try to be positive on the devices and share what your experiencing with this stuff...
Just using that word is enough to beat the drums loud on both sides...
So far I have not had a bad experience with this amp or dac.
The one thing I really like about it is to be able to take AC totally out of the picture....pure DC.....with so many of us wanting to get rid of any and all AC 'worts; this is a good thing to me.
My grados with this amp is totally wild...the bass is really , really tight and defined not as "dee[" as the LCD2's but OMG nice for what the Grados are...I put the Grados on the Lyr I have and the high end softens up alot. That said I believe the o2 is more accurate depiction of what is really going on.
I never knew what the Grados could sound like until I plugged them into the O2. This was without the ODAC in the picture at all.
I just got a O2 amp pc board from JDS and will put one together so I can have one my main listening room and take one to work!
All the best
