MSB Discrete vs Premier

And the director works with the discrete DAC?

The MSB web site says “ In keeping with MSB’s core design principles, the Digital Director seamlessly supports and augments all current DACs”.

I suggest you call your MSB retailer and ask.   
 

Premier without question.

I have owned the discrete and currently own the premier Dac. I found that with the premier the background became even more black. The soundstage also expanded and everything had more definition. With this move I have actually decided to go full MSB for my front end and sold my D’Agostino momentum m400 monos and he pre. I bought the s202 for the time being and do not find that I have lost anything in the sound. It did allow me to put money back in my pocket though. 
 

here is a incredible synergy when you pair their dacs with the amps. They are simply made to work together. I also was able to shed the streamer with the use of the renderer module for input with a gigafoil and lps. My dealer friend who also sells Innuos tested the gigafoil with renderer vs the Innuos statement with the pro-usb input. He too preferred the renderer gigafoil combo. This is nice as it cuts out close to $20k from a system too. 
 

If you can swing it I would go for the premier. 

Interesting. I own a Premier DAC too and I’m very happy streaming from an Innuos Statement Next Gen via ProUSB-ProISL module, I love Sense App that I prefer over Roon.

Premier with PowerBase and Femto93 is amazing.

I had the opportunity to have a home audition of the S202, here you can find my review on WTB forum:

If you can afford the Premier, go for it, you’ll be surprised.
