You already own the iFi, so plugging it to try it will cost you nothing, so just do it. That said, I've never listened to it, but I've heard the BlueSound DAC isn't very good. I own the iFi Zen DAC Signature V2 and the iFi Zen One Signature and I find their somewhat muddy performance lacking. You might find the iFi's affect works well with the Tektons.
Is it worth it? DAC question
I have a simple second system consisting of a Sugden A21, a Bluesound Node and Tekton Lore speakers. I have a spare Ifi Zen DAC V2 that I used about a year ago when I used my MacBook. Is it worth it to try and connect the Ifi as an external DAC or is the Node better as is? If I did try it, how do I connect the Node to the Ifi?
