Wifi connected Node 2 with Shunyata power cord for the Node2, Audioquest “Carbon” coax then to Mytek Brooklyn+ DAC which runs off an external “SBooster” power supply with “Signalcable” power chord.
I did one-by-one over the course of 1.5 years and each part made very noticeable improvements in sound. The biggest improvement was the DAC.
All that money in upgrades may have bought an nicer overall streamer combo DAC, but after I learned all the Bluesound software, I like it so much- I’m not wanting to change to anything else. Bluesound software is great for my needs.
The Mytek DAC was my final upgrade. The Bluesound DAC is very nice when you consider the price for the Node2, but if you are looking to improve the sound by about 20%, the external DAC may be up your alley.
