In a letter from Bob Stuart commenting on multichannel MQA, there is this unequivocal statement about our near future:
Quote
Finally it has always been possible to perform EQ and other DSP in an MQA decode - that is fundamental to implementation in an AV receiver or a DSP loudspeaker. This facility has not yet been implemented in PC applications, but it might come this year.
Very promising and it sets expectations for Meridian, both two and multi channel.
