Greetings Jesper,

Certainly, listing 'fatigue' is a matter of opinion; it can have multiple causes and be perceived differently in our various systems and by different people. The 9018 chip's (re)sampling behavior can be controlled (as well as the output filtration) via I2C. I haven't read the 9038 data sheet, but it seems there are even more control options programmed into it. My conclusion is that it is not wise to accept a blanket comparison statement about fatigue without direct testing using various control options. ...and by the way, one advantage to having older ears is that DAC 'fatigue' seems less an issue!

Hi & greetings to you as well ;-)

... Hmmm ... although I basically agree with what you are saying here the person who told me about this was one of the (main) designers of one of the very well reviewed/perceived and utterly expensive DACs based on the ES9018.

On the other hand, having designed DACs myself and worked with the intricacies involved in really tuning such a circuit, my experience is that even small changes may have quite a say in how a DAC is perceived subjectively. Thus actually saying "something" about how the DAC itself (i.e. the IC) sounds can be quite challenging IMHO ... That said it is my guess, and intuitive understanding, that if there is something in a circuitry (whichever it is) that causes listening fatique (to normal & sensitive persons) such a "trait" may not be easy to work around software-wise or otherwise - and might be perceived by more people ... Which is the reason for my question ...

Well, just my thoughts on this ...

... smiling at your comment here ...

Cheers,

Jesper

Even if I already opened a thread about this Sabre chip, I wonder if anyone here has seen or tried this eBay kit:

ES9038PRO Ulitmate DSD DAC LCD Display Successor of ES9028 DAC,Amanero/XMOS USB | eBay

Know nothing about this DAC chip, but tome serious DAC boxes are now carrying it.

Hi @Bunpei,

I designed and tested a new output stage called "Mercury" that easily handles the 9038 current. You can read a bit about it here:

Introducing the Buffalo III-SE-Pro 9028/9038

It will get it's own thread soon.

Cheers!
Russ
