I own a NAD C390DD DAC/amp with a BluOS streamer module and am listening to MQA ever since the MQA upgrade for both the DAC and the streamer was released in June 2016.
What strikes me is the fact that the firmware update enables full MQA unfolding in 24 bits with sampling rates varying (depending on the TIDAL stream album or downloaded albums) at 44,1 / 88,2 / 96 / 176,4 to max. 192 kHz
Meanwhile, the DDFA chipset which is used as DAC/amplifier is still capable of performing equalising settings like -4 dB correction at 40Hz, tone EQ and digital volume control..
Might it be that the design of the 35-bit
chip architecture offers so much headroom, that the 24 dB MQA unfolding resolution is maintained and the other EQ parameters are available in the digital domain using the rest of the 35 bits (= 11 bits) for this?
Or am I being fooled and listening to a non-MQA decoded output..? This would be however very strange since I double-checked ( see pic)
