mapman that is GREAT information. Thank you VERY much. I think I will KEEP the Modi 3+ (where it is now, in my 2nd 'office' system, connected via LONG usb C to my laptop) for practical reasons (small, USB C), and will ADD the M1 (bought for under $200) to my main system for 'heft and looks' (physical size) or the 'basement' system (bunch of equipment, lot of vintage receivers (no DAC), speakers, CD players (with AWFUL built in DAC) also for 'looks and heft'. The M1 does not seem to be terrible in the 'under $200' category.
