Reviews from owners and product review blogs, for Schiit products...amplifiers, from the Magni, Asgard, Valhalla, Lyr, Mjolnir are very good. There are various dedicated Schiit product threads with lots of Head-Fiers posting on them. Very few folks have made negative comments that I have seen.
There is a lot of brand loyalty. Jason Stoddard, one of the founding partners has personally answer my emails and those from other Head-Fiers. In fact, if you fill out the question form on the Schiit web site, chances are he will be the one to respond. (His answers are direct and brief… few words)
Jason reads the threads, post when necessary and goes to great lengths to support and inform Schiit customers and prospective customers. A lot has been written about how great Schiit customer service is.
I have a Lyr and I love it. From what I've read about the Asgard, I think you will enjoy it very much.
