Hi Motberg: I just asked/posted a reply/question about the U-16 regarding the very thing you speak-of (and that was of interest to me), namely, SQ:
" I think U16's inner resolution and layering in the midrange bands is amazing, I have already had quite a few moments just shocked on the additional midrange information the U16 can pull out of the recording.
THAT"S precisely the SQ 'descriptors' of interest to me; precision mid-band resolution/layering ! Count me in. (BTW, better than U-12 ?)
Regarding: " ....Also the U16 bass overall quality seems to be superior to the SU-1." -How would you qualify 'superior' ?
Many thanks,
peter
From memory, In my system, I would say the U12, Melodious, and last version of Audio GD DDC's were approximately in the same level..
The Tanly/HE-350 was a clear jump up from these offering a less digital sound and more accurate detail (like on cymbals) and better sound stage.
When I first got the SU-1 (before mods), I noticed lots of extra detail, but after 3 days break-in I could not take the harshness anymore and went back to the Tanly. (My speakers have a couple peaks after 10K)
Then I had the SU-1 PS mod and used 2 separate sets "Uptone LPS-1's with iFi DC iPurifier" (one set on SU-1 USB input side and one set on SU-1 output side) .. this removed the stock SU-1 harshness and then I could appreciate the extra detail of the SU-1 over the Tanly..
To me, the modded SU-1 sound was similar but superior to the stock U12.. a clear step up within the same sound environment...
To me, the U16 offers a different environment than any of the above (Tanly would be the closest), kind of like tubes vs SS, or analog vs. digital.
For bass, I notice that the bass lines are now sometimes distinctly within their own envelope, easier to discern, and maybe more correctly balanced against the midrange. Also tone and attack seems slightly more accurate.
I listen to mostly 70-80's rock and prog and worked in bands during that time so have a burned-in memory of standing aside various bass guitar cabinets and keyboard synths almost nightly over about 6 years.. the U16 ability to isolate and clarify the bass sounds from the rest of the mix helps bring the overall playback presentation closer to what I remember - but still within the limitations of my home stereo system.
