I checked and that was with FIR OFF!!! This of course is not possible since measurements show otherwise and I should not be able to hear the difference anyway. In one setting there were clearly more highs. I was surprised that this was very audible. My first test was to see if I could hear the effect of FIR filter on and off. Levels were matched and through Roon player, I could send the same song to both DACs at the same time. So I switched to Hifiman HE400i which I hooked up to an AB switcher to the d1-six and Topping DX3 Pro. It is fine for background listening but not much more than that. As the measurements show, there is barely enough power to drive these. Wanting to kill two birds with one stone, I did my testing with the headphone output. So be careful using this amp with any headphone that has variable impedance as it will act as an EQ (for better or worse). Indeed that is the case with 37 ohm output impedance. Translation: 'we wanted to build our own DAC because we know more than people who build DAC chips.'Īs I noted above, I started my testing with the unit's AC mains frequency set to 50 Hz: The version I tested as you can tell in the back-panel picture, doesn't have that option. Let's hope the objective measurements and listening tests show the value.īy the way, there is a 1000 Euro option to turn this into a streamer. Functionally though, it is response and works well.Īnyway, the unit is not a disaster but far below grade for a high-end audio product where one expects a lot in the jewelry department.

It is silver looking thing that would be out of place in an asian made audio gear at $300, let alone one at this price. I didn't take a picture of it as if I showed it to you, half of you would want to jump off a bridge. I left the unit on for that long before doing my listening tests.Ī really, really cheap, plastic remote comes with the unit.

The hour meter says 20.1 hours of being on. But as you see in the measurement section, I changed it to 60 Hz.
