I finally came to a good conclusion with my setup of the Tascam unit. About a month ago, I got a LPS (so called low noise) and its been running now stable where I had about 5-6 evenings totally focused on testing, listening and enjoying working with my Tascam unit and I felt I didnt get the good sound quality I expected, recording high res material from foobar2000. I still heard the little muddy soundstage and unprecise recording of crystal clear music.
Since I have 0 artifacts in noise floor, and I have calibrated my system to play -0.5 db as max tone when the tone is played at full volume, I would say Ive calibrated it pretty well. Rightmark does great measurements.
Then yesterday, I thought, hey, what if I plug in AES input from my Gustard u12 which has a 0.1ppm crystal, and mute the digital in, but allow the Tascam unit to sync to the clock signal ?
So tonight I have been recording a bunch of songs, with and without AES clock input from my Gustard U12.
And voilá. The soundstage got precise and adjusted to just what I am used to when playing through my whole system. For listening and recording, I use same DAC, and rest of the system is the same. I did several heat maps of the songs recorded and they seem to be missing some data around its noise floor compared to the original track, but also I use a 21 bit closed form DAC which gives me a realistic noise floor of -120db, while the original songs can be deeper than that being 24 bit which most likely explains why I miss some data deep down around the noise floor.
Even using the Tascam unit as a DAC, with only the Gustard U12 AES clock just staying there sending no data, and taking the analog output of the Tascam unit to my amplifier gives a great potential for sound improvement.
Suddenly I really got impressed by the Tascam unit, and not kinda disappointed which Ive been since I got it, thanks to external clock which is way more precise and sets the soundstage and quality to a new level.
Tomorrow I will continue with some jitter tests with and without AES clock.
