So I'm interested in getting an o2. I'm currently using the modi-vali. I'm beginning to realize that it can't drive all my headphones. Maybe only 2 of them. Is the odac necessary for me since I have the modi? Is the performance similar? I can save some money just getting the o2 amp. Any pros and cons I haven't thought of? I would have just gotten the magni but the gain seems too high that 5x. I set my PC volume at 100. Should I get the low gain mod on the o2 or just regular? I'm driving grados HF-1 and HF-2.
If you have a Modi, there is no point in getting the ODAC. They're both basically transparent to me and I had a hard time telling them apart.
I could probably do it with a T90 or some more expensive headphones, but not with an HD-650 or Q701.
O2 is definitely a better all-around than the Vali. I use mine in my bedroom with my Xbox 360 and it does perfectly for that.
Magni is also OK, but a tad brighter/thinner than the O2 with some headphones.
