Lamm made use of audio psychoacoustics in his designs, perhaps Javier is doing something similar. Sure he will not share the “secret sauce”, but let’s not pretend that it is something that is not if that is what it is.
I remember Lamm pre had a special effect on sound if i am not mistaken, a special analog signal processing for both channels inside the Pre-amplifier.
I do not know why Wadax is far better than other dacs but i think all good audio equipments should have good power supply.
Wadax DAC psu capacity is around 1000VA.
TAD D600 psu capacity is around 400VA.
Weiss Maya 100kg PSU
many audiophiles care about which converter chip used in dac (is it r-2r or not and ...) or which digital filter used and ...
in my idea MSB r-2r modules and dCS ring dac and ... non of those specs are the key factor for good sound. Specs are just Specs and have no relation to sound.
I also do not think Wadax secret is the implementation of the musIC feed-forward error correction technology.
coming Wadax Reference was a good event in digital world.
Daniel Weiss Response to a question about good dac design, as you see the first and most important is the PSU design:
"What are the most important things in dac design?
The usual digital and analog design guidelines regarding:
- Power supply regulation and distribution
- Ground handling – best is to have a balanced design throughout the unit
- Low noise design, i.e. low impedances and low noise active elements.
- Clock jitter handling, i.e. local clock generation if possible.
Good design is a matter of a lot of experience and know-how. There isn’t any simple recipe I am afraid.
