The guy in the video may be deluded....
But many others criticizing him can be deluded too...
(To be clear i can audibly distinguish any dac i ever owned but evaluating the dac performance ask for more than just plug and play)
What those selling low cost dac as well as costlier higher dac design and quality miss is that:
----The performance depend heavily on the coupling with the other pieces of gear...
--- The performance evaluation and optimization depend of the system/acoustics
--- The performance evaluation of any dac change a lot if all the gear pieces are well grounded...
How many here own a conditioner which need a grounding process ?
Almost all people...
Is your linear power supply grounded ?
Mine is too ...
Is you amplifier grounded ?
Mine is...
Is your pre-amplifier is grounded ?
Mine is...
Guess what ?
There is no relation between the sound of a dac in a well grounded system and the same dac in this system not grounded at all...
I know that by experience and experiments...
I never bought costlier ground box either ...
I designed mine...
No sellers of any piece of gear will say when they are selling their "masterpiece" buy a ground box (most are costlier than my system)...
Guess why they dont say that ?
