UPDATE 2020 onwards: Buy a Pi2AES and call it a day. DEPRECATED: UPDATE 7/18/2017: Need better computer audio? Buy a Schiit Eitr or a Schiit DAC with USB Gen 5 Still have money? Buy a pro audio (Lynx PCIe) interface, Rednet, etc. Still want to spend more? Go on a nice vacation with your loved ones. Things to do to improve your audio over USB: Try using linux if you can. MPD is awesome. Don't use optical on a mac. Don't use optical on 70% of random motherboards. Does your DAC cost less than $1000? If so, sign out of this thread. Don't come back. Enjoy your music. Do you have an Yggdrasil? If not, buy one before continuing. If you don't have the money, don't waste it on random USB defuckifiers outside of maybe the Wyrd. Try the Wyrd first. Do you have an Yggdrasil yet? If not, sign out of this thread. Do not pass go. Do not collect $200. Have an yggdrasil and still unhappy? Don't buy the regen. It's a downgrade. It sounds different but after a while with speakers you'll understand what I'm saying when I say it's a downgrade. Get the Lynx E22. The Mutec 3+ might be good, but until Marv, Christian, or I get to listen to one, I am going to remain skeptical. Still unsatisfied? Buy a house. Get married or find a life partner. Have kids or adopt some pets from the local shelter. Still unsatisfied and those little rugrats haven't bled you dry? Want to indulge your audiophile nervosa? Move to vinyl. Come with a big ass wallet. Expect to start with a "modest" $1000 setup and slowly spend more over time until you wake up with a $2000 cart in one hand, $10,000 in tubes for your pre based off some RCA design from the 30s in the other, dried wood glue all over the side of your face, and "azimuth" tattooed on your ass.
