Hello Audiogoners!
Not trying to hijack the discussion, but since the GRIMM AUDIO MU1 was mentioned, just wanted to share some pretty cool facts about the MU1 combined with Audio Note DACs or other DACs with the AD1865 chip (ie. the new Linear Tube Audio AERO DAC).
1. The MU1 can convert the bit depth to 16, 18, 20 and 24 bits...so an 18 bit depth can be selected for these DACs, as it the maximum they can support.
2. It can convert hi-res files above 96kHz (again maximum of the 1865 chip) to 96kHz or below, so your hi-res PCM or DSD files can be played.
3. Has a built in remote control volume...which an Audio Note system does not have (except for a Cobra integrated). I get that purists may not want to use this feature all the time, but it is completely seamless and EASY to disable on the fly, as well as being VERY convenient.
4. Has Roon Server (aka Roon Core in the past) plus optional local storage for your music all in one box...again convenient.
