Disassembling BlueSound Node 2i?

The impedance issues with normal RCA connectors in s/pdif transmission are well established.  A few 75 ohm RCA connectors are out out there, but many dispute whether they're really 75 ohms in actual use.  And who knows about the sockets that the equipment manufacturer is using?  Many (most?) of the serious high end stuff uses BNC's.  So, at a minimum there's a theoretical basis to prefer true 75 ohm BNC's and cable rather than whatever cheap, "digital" RCA cord came with the kit.  Ditto the connectors on the gear.  And others have clearly proclaimed to hear a difference.

But are there audible shortcomings that I'm going to hear in my systems?  Doing a comparison is obviously very hard.  And the audibility would certainly depend on the system and source. I'd be amazed if it were audible on a mid-level system streaming Spotify.  But playing through a truly high end DAC into a very resolving system?  Well,  maybe.  OTOH, maybe the Node 2i isn't resolving enough to tell the difference in >>any<< system anyway. 

What this really comes down to is leaving no stone unturned.  I ended up with 2 Node 2i's and I'm happy with them.  One is in a simple, mid-level system.  The other is in a very resolving, true high end system.  I figure that in the latter case it can't hurt and it might help. Up to a point the work doesn't trouble me, I enjoy it.  But not at the risk or breaking stuff.

I found this on the Vault to open its case. No idea if it’s the same on the Node but I wouldn’t be surprised if it’s the same.

“On either end of the recess in which there are the power inlet and ports, there is a ¾” by 2” (approx..) plastic cover. There is a very slight indent on the bottom of each.

Using your fingers or a thin blade, pop off these covers.

Underneath each cap there is one small Phillips screw. The screws may be covered with a piece of transparent tape, sticky on both sides. Remove the screws, and one side of the cover pops off.”

And that was more the point I was trying to make tbh.
However as a member above has posted, you maybe able to get into it and then you maybe able to change out the RCA output socket indeed.
Good luck!

Here's a solution to the Bluesound Node2 disassembly:

Basically there are 2 caps next to a heat sink (this unit runs very warm anyway) that have failed.  I am going to try to take this to a local repair shop and let you know what I find.
