Fantastic! just bought a used Sonnet Morpheus with i2s to replace my onyx (dac3), and use it with the Metrum Ambre streamer, a nice improvement over the onyx in my system. My LTA mz2 (wish I had George’s mz3!) preamp does not have a remote so I’m feeding the Morpheus into it with variable voltage, running the LTA with volume all the way up (effectively defeating it), and controlling volume with the DAC remote. Works wonderfully and now I have a remote! Probably a better volume control too… I don’t see a downside to this arrangement but wanted to put it out there for any comments and to see if any others have tried that. I will try amp-direct (lta ultralinear) soon but might miss the 6sn7 tone. Adagio has the same type of volume control, wonder if that’s worth trying with the mz3 in the same way. Fun things to try.
