I much prefer the Bifrost into the Lyr than the Dragonfly. If you have optical and/or coax, the Bifrost without the USB option is a steal. There will be a good benefit to the Bifrost but I wouldn't say night and day. More defined bass and smoother, clearer mids and highs with a little less grain.
What headphones are you using? I can hear a definite difference with my HD700 but when I had the HE400, not so sure.
Hey guys, thought I'd ask a question here since I absolutely adore the dragonfly. This may have been discussed before but I probably wasn't paying attention. I just got a new PC which, unlike my last one, has Coax and Optical S/PDIF out. I love the dragonfly performance into my Lyr. Question: How does something like a Schiit Bifrost for S/PDIF compare with USB-> Dragonfly? Will I hear any benefit? Or perhaps another DAC?
