MSB Discrete vs Premier

I suggest you investigate the MSB Director that is an update to the MSB Premiere DAC. The MSB Director costs $14,000 and adds a third box to your stack (DAC and power supply) plus additional cables.

See MSB Director Link for more info:

"This is a DAC Upgrade. This works with all existing Discrete, Premier, Reference, and Select DACs. Any version of the digital director works with any version of our DACs. It is an additional product chassis that marries with the DAC to do extraordinary things. New firmware will be required for the DAC. Current input modules are removed from the DAC and installed into the Digital Director. With the Pro ISL and Optical control link providing two way communication will allow the DAC display and controls to operate the Digital Director as a seamless experience. This will not work as an independent product. The Reference and Select level Digital Directors have integrated linear power supplies, whereas the Premier Digital Director has an integrated switching power supply".

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.
