I ran into a slightly concerning issue while switching inputs a whole bunch... A ghostly high pitch noise that seems to go away by restarting it, haven't tried to recreate it!
I remembered reading online that the optical input on the modi multibit "might" be superior to the USB input. So I spent some time today downloading a portable copy of Foobar2k and using WASAPI to optical and ASIO to USB from the PC, playing at the same time. (96k FLAC instrumental, then some vocal and some 88kHz optical 176kHz USB DSD->PCM files) I kept switching between the inputs on the Mimby trying to detect any differences, but I couldn't note anything discernible ...
But about 7 minutes into this A/Bing by pressing the input switch on the Mimby, quite often... I noticed a weird subtle high pitch ghost ringing, noise that mocked the music being played focused on the left side, on both inputs. I wondered if I had been playing the music too loud and broken something in my testing! It did not go away until I decided to switch the Modi MB off for 10 seconds.
Whew. Seems back to normal now. But perhaps it's not a good idea to switch inputs too often without rebooting the Modi eventually? Bought the Mimby in December.
...perhaps it had something to do with a DSD->PCM file being played, with optical set at 88kHz and USB at 176kHz. Because Schiit got real when it realized I was playing a DSD file. lol
Equipment:
Foobar2kportable ASIO -> USB 2 port -> Plain ole short USB 2 cable from an external drive -> Modi Multibit -> PYST RCA -> Jotunheim -> SE -> Stock Cable HD 650
Foobar2k WASAPI (event) -> optical port -> Radioshack 3' optical cable -> Modi Multibit -> PYST RCA -> Jotunheim -> SE -> Stock Cable HD 650
*using the latest USB Mimby drivers were a hassle but finally got them working.
