Hello,

I have owned a TDA1543 based Kusonoki style (passive I/V, digital filterless, non oversampling) DAC for almost two years.
You can have a look at the measurements here.

I find that this kind of implementation (Kusonoki) has a very distinct signature that is not very compatible with the reproduction of symphonic music: it's dynamically challenged, coloured, veiled and lacking at the frequency extremes.
One could almost call it the digital version of single driver speakers.

The TDA1543 was chosen for it's ability to bypass the active output stage but the TDA1541 is technically a far superior chip.
I have never heard Audio Note's or any other non-TDA1543 based NOS DACs but it would be interesting to know whether these qualities are due to the use of a economy version chip, passive I/V, non-oversampling or the lot.

Cheers,
Tuga
