@tom23 , thanks for that link. The way the M Scaler is described is 100% the same way I’d describe the effect my Innuos PhoenixUSB adds to my system. I’ve since read that others who have both the Phoenix and the M Scaler also describe the effect of each as being identical. To be clear, I’ve read that others have said both together sound the best, but on their own, they both seem to add the same effect.
With this in mind, while I love my PhoenixUSB and couldn’t be happy without it now, I feel like adding that effect again might be "too much of a good thing".
In the link you mentioned the reviewer noted that maybe the Chord Dave has better detail than the TT2/ M Scaler, the Dave with all its detail might draw your attention to the detail and as such enjoyment of the music could be diminished. Another example of "too much of a good thing".
I do have a bit of a concern adding an M Scaler might be similar considering the effect the PhoenixUSB added, while welcome, might be overdoing things if that effect was added again.
The other factor is that upsampling is limited to 176k or 192k (not sure which) with my Gryphon Diablo DAC module. The review I linked noted the M Scaler sounded awesome with his Gryphon DAC, but he didn’t have the Phoenix, and he was using a homemade audiophile modded PC as a streamer.
Hmmm....
Maybe I'll seek out a used M Scaler and just give it a shot. Can always sell it.
