I have never heard either, so I can't say. What I can say is that the Schiit products are very highly regarded on Head-fi (though some, including myself, would say they're over-hyped and FOTM) so a lot of people will be recommending them over the many viable alternatives.
The fact is, the cheap Schiit products (like the Magni, Vali, Modi, etc) make much less sense when you're out of the country and they're not cheap anymore.
If you're paying nearly $200 for the Vali, it's no longer a good value. There are plenty of other products in that price range that are worth considering. Project Starlight, for example. Or maybe the Little Dot.
I have no idea if the Bravo will work well with the Q701. But for the price, it's worth trying. If you don't like it, resell it. Also, be sure to check out the classifieds on here for potential deals.
