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.


Thanks for the info. I have to admit that I have not listened to any high-dynamic symphonic music with the Wavelength Brick DAC yet. I'll sure give it a go when it comes back from surgery.

Their website does mention this: "These DACs incorporate the TDA1543N2 (select top 5%) DAC chips with passive I/V using Shinko Tantulum resistors..." What exactly does "select top 5%" means I have no idea. Are there crown version  of this chip like the TDA1541? I didn't see one when I opened up the DAC.

The TDA1543 is known to have a rolled off response at the high frequenices. I knew of this before getting the DAC used; another reason I was skeptical of this DAC. I listened carefully between my Adcom GDA-700 and the Brick, and thought the Brick souded much better. Not dull or rolled of.

Cheers
