Yes my apologies, just double checked and it’s the 1120. The 740 should be fine unless there’s been changes as it produces 108 db sinad at 2 volts @tmukh.
For clarify, if you are referring to Gene's measurements, he noted that:
This can be seen by the 3rd harmonic distortion down 108dB below the fundamental 2Vrms output drive at 1kHz.
That's not SINAD!!
It would be tough (though always possible), for the MRX to get 108 dB SINAD, when the DAC chip alone, managed only 106 dB, by the time you factor in the other chips such as volume control, buffer opamps, switches etc., the accumulated THD+N could easily bring the overall SINAD to near or even below 100 dB at 2V. No doubt, the MRX740 is still "transparent" enough, for me anyway.
