I have a $80 dongle DAC I tried based on an excellent review with detailed measurements. The numbers said this DAC was a top of the heap performer that outperforms another popular “audiophile” DAC that costs 10k ( also measured by same tester for comparison). I use it only with headphones but based on what I hear I can’t disagree with the rave review. This thing is clean clean clean sounding and nails all the details and dynamics. A real giant killer!
I also have had a Chord Mojo for a number of years. This was also measured and reviewed by same source . Conclusion was the measured performance does not match the hype. I still enjoy the Mojo though It sounds much different than the $80 giant killer. Warmer and smoother but you don’t hear as much detail and dynamics . Very different sounds Which sounds better? You decide. One thing I can say with confidence is that you need not spend a fortune to acquire a top notch DAC these days . 10 years ago the story was different . Technology advances and reproducing even high res music well these days is no longer rocket science. Of course people buy stuff including DACs for many reasons. Measured performance is important to some whereas others rely solely on their ears. It a personal preference thing like always
