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

DH Labs makes two very good optical cables - I have used the one in this link many times and a friend just put one from his MAC Mini to his Schiit DAC and it sounds pretty amazing

They also have a glass one which is probably better better

To get anywhere near that level of performance with a good SPDIF RCA cable would cost more than either of these two

The DH Labs SPDIF RCA cable is not as good as their optical cables

I’ve had other optical and SPDIF RCA and TOSLINK cables from companies like Chord, Van den Hul and prefer the DH Labs offerings by far

KLE Innovations also has a couple of exceptional SPDIF RCA cables for around $200 and $300

I happen to have the Node 2i and it’s analogue section is outstanding i.e. IF you treat it to great cables.
 But it might be a more cost conscious solution to use the onboard DAC in the Receiver - the analogue cables can get quite expensive

Thanks for all the suggestions. I did test RCA jacks from Bluesound vs optical cable with my Anthem 1120. I decided I like the Anthem more than the Bluesound DAC but I'm not actually sure. They both sound good. As far a Digital Coaxial, I don't want to pay a lot of money for the cable 
I just checked out the links. It looks like I can get a very inexpensive coaxial cable. I thought I would have to spend into the hundreds for one
