Proper DAC Upgrade for my modest system.


Looking for some advice from people with lots more experience then me

My local dealer has recommended the RME ADI-2 DAC, or the New NAD 658. Buying a DAC is "hard". But was looking for some veterans thoughts. The NAD I could replace the Yamaha Streamer and get some money back.

Anyone have an opinion of the Wadia 122 DAC? I got one on clearance so decided to pull the trigger, its 100% better then the Parasound zDac Gen 1 I was running, but making sure for around the $1200 ( My budget ) price point I am making the right buy.

System is WXC Streamer --> Wadia 122 DAC -->AVR/Pre-Amp - B&K 125.7 Bi amped to KEF R11’s via Rocket 44’s.

I use Tidal for all content - I don’t do anything other then stream Tidal and some Apple Music if certain songs / albums are not on Tidal. Some day I might progress into "higher res" but the cost of files seems a low ROI vs Tidal at the moment.

Appreciate everyone’s insight on this topic.

John always has me demo equipment I'm interested in before purchasing. Makes a big difference in deciding what's right for your system. 
Be aware that the NAD 658 does not YET have Dirac.  That ability should come in late Jan according to NAD.  I would agree with some others here that all of the DACs being mentioned here are pretty damn good and the differences are likely to be pretty fine between them - but the difference Dirac Live can make is NOT subtle.  It clearly sets the 658 apart a bit.  Add the preamp, phono input, BluOS and Roon endpoint ability, and balanced inputs and it is worth a look. Mine sounds great - but checking daily for the Dirac update...
At $1200 I recommend you audition the Schiit Gungnir Multibit. They currently have several B stock units for $1169 + shipping.
