In Reply to: this digital filter is the worst possible digital interpolation filter to use posted by chuck55 on November 16, 2023 at 21:43:58:
The article you linked to is nearly 20 years old. Lots have improved since then. Is AudioZone the DAC maker still in business?"By removing the digital filter altogether; the impulse response is essentially perfect, without pre or post ringing."
Solving one problem perfectly and not addressing the many others is the easy way out and not a TOTAL solution.
"But from what I have read, NOS DAC's are supposed to time better."
Again, only one parameter is addressed.
From the ~20 year old article you linked to:
"Perhaps these unsuppressed images [in filter-less DACs] were partially or wholly responsible for the warm, slightly opaque yet relaxed, easy-going nature of these DACs?"
Sounds about right based on my experience with a couple NOS DACs. But here's my take on it. "These unsuppressed images were partially responsible for the warm, veiled, and dynamically challenged, almost lifeless nature of these DACs"...... UNLESS one is playing 'simple music' like a female vocalist and piano. Play anything more complex and it all starts to fall apart sounding congested and compressed.
