on other forums, many are raving about MQA and DRM...
MQA is a std. that meridian meets, and is something of a "spin-off" from meridian, or bob Stuart's new project, etc.
it is designed to go from end to end - from the source on the masters to the last DAC near your ears
Chris at Computer Audiophile plans an interview with Bob Stuart in the near future, and DAC makers and others with a technical background have been combing thru the MQA process to try and figure out what it really does
but I suspect we will have to actually listen to it... ;]
