Excellent review Ichos, been waiting for this.
You mentioned as a con that competition can be dynamic and holographic. Please let me know what are those options. I recently had and sold SMSL SU8s and A30 Pro, they were not dynamic sounding for me. I have been looking at DAC/AMP combos for a while.

Thank you.
Let me clear that the K9 PRO is as dynamic as needed to sound totally convincing.
Other options that can be more holographic and dynamically contrasted are more expensive discrete designs like the Flux FCN-10 or the Violectric V226 which can't touch the K9 in the DAC department.

Ok, thanks. I will see if I can demo K9 Pro ESS.

You should, it is in the top of my recommendation list.

Very good review! with Pros/Cons spot on! Exactly mirrors my experience with my ESS version.

Thank you very much, one of my principles when reviewing is to be honest.

I dont think it sound any different from any amp/dac out there especially when it comes to being neutral and transparent.

Have you compared?

@NickT23
It is very different from the THX amps out there. What makes K9 Pro special is that it blends the musicality with transparency.

Not just THX any other nuetral amps as well and this includes delta sigma dacs. Have to do honest a/b test. Most of the time, I unable to discern the difference. And what do people mean about musicality ? Coloration ?

Thanks for posting this review. Do oyu know whether the USB input is galvanically isolated?
