Connecting Bluesound Node 2i to Anthem receiver


My connection is optical to my 1120 Anthem because my installer said the Anthem has the better DAC. Am I better off this way or using the Bluesound RCA jacks to use the Bluesound DAC. I have read posts that recommend digital coaxial. I am not looking to spend a lot on coaxial if this is the best hookup. Thank you

The only way to know if there is a difference between the optical and coax connection, and whether you prefer one or the other, is to try it. It isn't just about the cable, the implementation of those options at either end might make a difference. Blue Jeans Cables in Seattle makes excellent cables of both types at very reasonable prices. A 3' coax from them is $18.50.

@galleybob - You're mentioning three options: digital optical, digital coax, RCA jacks (analog). As @sfar said, you won't know which you prefer until you hear them.

That said, I'd probably avoid the analog output of the Node2i. It seems likely your Anthem has the better DAC; and what's more, if you are using ARC, any analog input will be re-digitized by the Anthem, while the digital signal will be processed without reconversion. As a rule, I try to avoid extra AD or DA steps.

BJ toslink only worked in some devices - bad tolerance terminations.

IF you decide to go that route. I like Morrow for SPDIF cable, on sale of course. Made to order no upcharge for XLRs.
