Cable info

I would echo the suggestion of spending your money on a better external DAC than the one in the Node 2. 

I can't see the logic in spending a lot of money to replace the already good interconnects you have to try to improve the sound quality of a DAC included in a $500 piece of gear. 

Take what I said with a grain of salt as I don't know how good the sound quality of the RCA outputs is, I connected my Node 2 to my Auralic Vega immediately.  I'm very pleased with the sound quality in this configuration, but the Vega doesn't do MQA.  I am skeptical that MQA directly from the Node 2 would be better than what is coming out of the Vega.

I picked up one pair of the new Cardas Clear Cygnus RCA Interconnects to use in a different system I put together, used between my Allnic T-1500 300B Integrated amp and MBL CDP. I was shocked to hear how it bettered many interconnects that I find to be very good and have highly praised.
The Cardas Clear Reflection, Clear Interconnect, and Clear Beyond cost more and sound better at the usual pay a lot more and get a bit more improvement price.
Feel free to PM me if you have specific questions.

I did extensive a-b comparison between rca out and spdif out from my vault 2 using same nordost heimdal series interconnect.
There really was NO comparison in my system.
But you are looking at 2k for a Brooklyn so.......

Depends on your budget.
Node2 is only $500 so would not make sense to spend same again on RCA cables. The nordost heimdal are probably over 1k new and I doubt the node2 dac is any different to the vault2 DAC.
I know the Mytek liberty is about 1k new the Brooklyn about $2200 new so it all depends how far you want to go.

@luvrockin The Node 2 responds very nicely to connecting it with GREAT cables - both power cables and Interconnects-

It also responds well to having cone feet installed underneath - I have mine sitting on a granite tile. I have tried both brass cones and wood cones and they both provide improvements in extremely fine details and imaging

I use cables that I made myself and the improvements in sound quality were amazing.- see these links if interested...

If you are not a DIYer then I recommend cables from KLE Innovations

Their gZero3 Interconnect is excellent and having reviewed a lot of their product line and exchanging many emails with Keith Louie Eichman about his cables and RCA connectors I have no reason to believe his power cables would be less than stellar.Also look at the more recent QFlow3 IC’s

You may notice that the connectors I use on my IC’s and Speaker cables are from KLE Innovations also.

Some may think me CRAZY to outfit the very affordable Node 2 with cables that cost more than the unit itself, but I consider my cables more important than many components, simply because I have found through extensive component auditions, that even the most modest components perform much better with good cables.

My Node 2 now sounds so good I have stopped looking for another device for digital music.

It is very spacious and so dynamic that I consider it is the most realistic reproduction I have encountered.
It presents an exceptional level of micro details that allows it to reproduce the most granular venue acoustics I have ever heard in any system

Great cables allow the Node2 to really strut it’s stuff

FYI: my system components are:
- Node 2
- NAIM 5i MKII integrated amp
- Gershman Acoustics Sonogram speakers
- The DIY Power and Interconnect cables (links above) and my DIY speaker cables
