Yep: heard it… heard it very quickly (alas) on the main rig (Apogees with the ribbon MT’s). Couldn’t go beyond -11dB (with or without any EQ) without hearing “glare”(?)) there. Hence the at that time queries… but, pushed on (and on)…. Couldn’t get to where I wanted before distortions ruined it. And, since goal there was FM style adjusting… I just moved it upstairs. Far more forgiving. Way different use-case. Smaller room, NOT Apogees, near-field, usw.
It was mostly intellectual curiosity, having done this since forever…. (I’m pretty damned sure that -12dB is the limit (from my listening - and “measured” by the FB interface)…. On proper classical, other music with far less total dynamic range may not be an issue). But, last I checked -12dB is two freaking bits of resolution; and that off of 16 bit max originals…. Limit - for me - I’m mostly a classical guy on the big rig. Hearable on anything with ribbons (my Apogees and my Koss ESP’s)… almost like VTA set horribly wrong coupled with too small a tracking force… <yikes> (yes, I exaggerate, but for effect).
All said, for near-field, with decent or better point source(y/ish) monitors nearfield… it is triumphant; a total keeper. I forgot how much I *love* a proper Fletcher-Munson curve applies to the music. My first amp (integrated) was my dad’s old HK Integrated, that had knobs for different phono EQ curves (this is pre RIAA wins days), and Loudness (in addition to bass, treble, balance). T’was mono, and fully tube. THAT was my exposure to FM curved low-level sound (very young… 11 or 12). Mimir in my office rig did that again (alas, distractingly at times) today.
TL;DR
Mimir is an excellent DAC (standalone), not quite (for me) Yggy level (usual disclaimers, yada yada).
IF one wants to use pEQ and/or Loudness… you can only do so to the extent which you reduce your digital resolution “headroom”. This is a pretty decent range, but it is not huge. It will depend on what your musical (and source) preferences are. It is FUN to mess with - and not expensive -, and can be extremely rewarding. In my desktop system? Boom! Win. Selling Sys and Modi. Mimir rules there. Everyone should have one as the new “reference” unit. (At straight-through 0dB, no EQ, on the *real* power supply, etc,)
