There are many audiophools out there, you can see this on some of these posts on this thread and the guy in the video. You have people that claim they are the only people that can take a $200 piece of equipment and make it a giant killer, or if you pay more than $5 for a cable, you are a fool. Then what’s scary is the guy in the video that calls himself a mastering specialist and he can’t hear.
Decades ago, I owned the Audio Alchemy pieces with the outboard power supply and this was my 1st time I used the i2s interface, it came with the AA equipment. How did it sound? Ok for its day but would be terrible today. Since then I’ve owned 6 other dacs from Audio Research, Wyred 4Sound, Auralic, and a few from PS Audio. The clown in the video only thinks that all dacs have chips in them, so what does this guy think about fpga based dacs?
There are big differences between dacs, good and bad. A friend brought in a bunch of dacs into his home for a month so he can determine which 1 would he buy. The dacs ranged in prices f I’m $2500 to $15k. A few of us evaluated these dacs and there was no 1 winner. Only 1 person liked the most expensive where a couple people liked the middle of the road dacs. Then a newer fpga dac came out and blew all these away.
As for somebody that claims a dac doesn’t make a big difference in the overall quality of the total system, this is a fallacy. If the source is bad, you think a pair of million $$ speakers will fix that? Nope! That’s like saying a $500 power cord is snake oil when I heard a $200 Nordost power cord make a huge difference in sound with a $5000 McIntosh integrated with magnepan 20.1 speakers. Just think how a better power cord will make a $100000 amp sound? Cables are like tires. I spend over $500 for a Porsche rated tire (not tires) which makes a Porsche handle to its fullest extent whereas this same tire on a Toyota would not make the Toyota handle like a Porsche. But, on the other hand, you put a $50 Toyota tire on a Porsche, this $100,000+ car will handle no better than the $18k Toyota
