Anytime! Yep, they're dynamic at 25 ohms, so it doesn't get much easier.
As for the Schiit stack, I can't really say how they'd stack up (pun intended) to the others, since Schiit was my first foray into headphone amps. I don't actually even have the DAC part of the Schiit stack yet, as I couldn't afford to get it at the same time as my Vali 2, and my motherboard's internal DAC seems to be more than sufficient at the moment (Gigabyte Z97MX). But from what I've read from other Head-Fiers here and from other reviewers, I've hardly heard a negative comment about them, with the general consensus being that they outperform combos well above the Schiit stack price range. Some claim that they can't really tell the difference between the Magni 2 + Modi 2 and the Objective 2 ODAC/AMP combo, so if you wanted a combo unit to save desk space, that might be an option to look into. You can customize some of the features on the Objective 2, apparently. My only gripe about my Vali 2, and I'm really reaching here, is that it comes with separate rubber feet to put on the bottom, and I couldn't quite get them to line up perfectly. But that's my own fault, haha. I do wish they came pre-installed, but all in all, it's not that big of a deal.
