Chris Martens has a review on Hi-Fi+ of the outstanding Schiit Yggdrasil and Ragnorok DAC/Amp stack. This is the high end of the Schiit line and they are outstanding. I have spent several hours over the past year listening to them at various meets. They aren’t cheap and the aren’t gimmicky. They are simply excellent products and a good price. One of the best price performing stack on the market. Someday and might be able to purchase these but for now I revel in my Bitfrost/Valhalla stack.
