I'll just put it this way . I had a Teac UD-301 and a Cavalli Liquid Carbon and I would pic the QP1R all day long but adding the Yggdrasil it is much more in every department IMHO. I don't know if other DAC's would do but the Yggy killed it as it should for the money I spent. It is not that I paid for it that it sounded better it just does. I was looking for a setup that sounded as good as the QP1R and this is jist better , The QP1R is just about the best sounding Dap's out there . I have not heard them all but it is damn good at three times the price for sure. I would love to have the X7's interface and streaming but it doesn't come close to the sound quality. These are my opinions so that is what it is.
Thanks for the reply, I've heard the Yggy and I agree its better than the UD-301 (but not 6x better) but for my sound preferences the Hugo TT, Master 7 and Pagoda are the ones that I liked. I got to try those DACs at a friends house with some great amps that included a Liquid Gold, Liquid Glass, EC Balancing Act, and a few others. The HD-700 with the Pagoda and Liquid Glass was heaven, very dynamic, great sub bass, smooth mids and highs that I liked better than the HD-800 on this setup.
Since I don't use a DAP very often (once or twice in 2-3 months) and its only for when I'm traveling sound quality is not critical due to the environment and headphones that I travel with (QC-15, XS or Momentum) so the Fiio X3/X3ii is more than adequate, but I can see for someone who is using a DAP everyday and with better headphones the QP1R makes sense.
