Legendary DAC modul TDA1541.
Super Digital Filter from Sony SXD2214s.
good parameters near 110db like 18 bit sistem...low distortion and good sound...
Nichicon KZ series , Murata, carbon resistors
Super discrete bufer
may make for orer
The scheme is below
High grade is output transformer with 300 Henry with 2 V RMS and 7 OHM output impedance!!!
DeLux grade is the Russian 6e6p and output 2V and 3.5 Ohm output impedance!!!
Also it able to build to vinrage CD...
YOur qestions?

It's image that show
This variant in a picture is the use of a transformer
-6-7 Ohm output impedance.
Variant two-
use the transformer.
After emoter dat is:
30 V, 1 Kohm, N=30:2
I = 20ma
Out data
2V RMS ,7Ohm, 0.3A
If use Russian 6n6p (double) it's able to have 3.3 ohm output imopedance
This two variants have ability for non-use caps at output of TDA1541A and Negative Feedback
