I've ordered a 350 F Sport with ML. I've posted a few questions here about the Mark Levinson system in the IS and have been very impressed with the audio expertise available in this Forum.
While I wait until November for delivery, I want to see if I get some of my favorite music together for the ML

So, here's another question for the audiophiles: what media should be used to best make use of the Levinson 7.1 surround sound system for music only purposes?

 

320kbps MP3 is good enough because ML does not deliver completely pure sound (see my review in another thread). Streaming with BT lowers however, the quality, so use USB memory storage.
