Calling DAC experts for ultimate PCM63 DAC

I told you there are 2 DACs in the chip and you said I have a different maker of the chip.

This colinear, is my hypothesis why the dac is not neutral and elviukai describes the sound as such.

The datasheet doesn't explain the choices and reasons behind the choices of the design and the pro/con of this.
You said more than something about 2 DACs and your description of how it works was less than accurate not that it matters. It works the way it works.
The job of the datasheet is simply functional. It tells the user how to use the chip and no more. All that audiophile horse hooey is on the user not the maker.

It is true that what I said needed maybe more context and introduction.

The way it works matter in the first order... I think it matter a lot, when talking behind scientific.

A dac with one 2r2 ladder vs one with multiple ought to sound different, even if both measure 'well'

The ultimate pcm63 is still an ultimate colored DAC based on that design, the design is not for the sound, it is to reach high performing statistics so that it sells, note I never heard the PCM63, and I am far from thinking that it sounds bad. I am sure that it sounds awesome as the rarity suggests, demand = quality.

The knowledge of the topology of the chip helps identify and classify the sound.

Without it, pure subjectivity. With some facts in the background to base a pathway you can progress, learn and move on.
 
You know , I just 'dumped' 16x new un-obtainable Blackgates NX-hiQ NP, series into my pcm58 dac, they bypass near the dac as well as decouple the silmic2 in the opamps, can't sound better... so for me there will be no 'ultimate' next dac... I don't have much left. All I can say is that it was worth it, experimenting with even 1uf polycarbonate axial films...

I just found once such cap for sale for 50 LOL, I remember when capping my tda1541 with polycarbonate it started oscillating.
 
You don't need to hear any high ultrasonic frequencies to appreciate audio, a violin or soprano won't go past 4k, and the important harmonics are very low level at 8k. I rarely see anything above 6khz. Above 12khz it is mostly room boundaries.

thats funny because when I or my audio friends hear organ records frequency of 12-15khz is important. if there is deficienty in speakers in that region(lets say -4db) they(organ) sound dull. its like transport them from church to well damped recording studio. Function of home audio system is to reproduce what is recorded and EDITED( most would surpsise to hear unedited human vocal recrded in studio)

(Un)fortunatelly there is many kind of audio enginiers-
Most audio engineers filter high frequencies out of the recordings because it is annoying information which is not musical,

such as something dropped, thermal expansion of objects, sheets of paper turning of falling or electric motors noises.

People sneezing and coughing, that creates loud sounds into the 18k +, so it is obviously filtered.

The very highest note is C7, 4180hz, as long as you can hear to 13khz you don't miss anything important.

( people will get accustom to hear a deficient sound system, n.o.s., passive i/v etc.)
I cant coment about other people needd but i miss that extra razor sharpness in hearing when i was <30yo. I still hear 14.5khz, 5 year ago i still heard 16khz, 20 years ago around 17.5khz.

more than 20 years i eat/unpack same pack of curd, more than 20 years i go to park for run where i hear same trees leaves or hear my runing shoes hiting ground , hear water droping/filling, hear that aditional ultra high tone of car tyres produce. All this SLOWLY fading away. Actualy in audio reproduction there less noticeable, but more in life nature sounds IF you rememebr how they used to sound in the past. Again its sonic memory. I would not notice it if not my work. Another funny thing is that sometime i hear my speakers designed back in ~2010. they have too much uper bass, midrange is recessed- and higher octave(12-14khz) is dull. but it wasnt 15 years ago. to sound balanced i need turn on EQ - reduce 100-300hz by 2.5db, increase 800-2000hz by 2db and increase 12-14khz by 4-5db, then speakers sounds like I used to hear them with SAME record is SAME room.

Its a great advantage to have a circle of audiophile minded friends. Take care of each another.

I am over 40 and my hearing changed a lot recently. I played same music and I perceive sounds in the 1k 2k region louder, my perception is more accurate and sensitive, however I am like you I miss that near ultrasonic, I feel the air vibrate but I cannot hear above 15k anymore. It used to cause me great trouble in ff passages on vinyl records with high frequency distortion, many pressings have that issue. Now I can only feel there is distortion something is off but I cannot hear it.
