Ive had two items to Schiit service in just the past two months
The first they fixed, for free, and within a week. Great!
The second they shipped back to me telling me nothing was wrong, when in fact - there was definitely something wrong. They really dug their heels in on that one, leaving me unsatisfied and unhappy with the purchase. That one went back.
I tend to suspect the quality of Schiit gear is rather low. Lower than maybe most everything else. Good for the cheap throwaway DACs and such, but I would not pay serious money for anything else in the line. Even Topping and other Chi-Fi feels higher end, in everyday use and experience.
I also tend to believe Schiit is aware of the issues, and asks the customer to deal with more little pops and ticks and buzzes than they should really have to. The guys come off somewhat cool in their writing and online presence, but in actual interaction aloof and arrogant.
