I am afraid Audio Science Review is a completely useless site for any useful information on actual sound quality. Having been an audiophile and a scientist over the last fifty years. Amir or what ever his name is… is a guy obsessesed with measurements and is completely clueless about musical reproduction of sound. I can appreciate his interest in measurement… but the relationship to sound quality is virtually non-existent.
I have owned DACs costing in the hundreds of dollars, $2K, $5K, $10K, $17K and $22K. I assure you theyor sound is far more correlated to price than his measurements. This is because companies that produce good DACs start by using parameters…. Then they listen to then, to make them sound good.
Stuff that measures flat tends to sound terrible. Audio Science Review is really good at producing pretty charts. After put together a fantastic sounding system… go back and see what his charts look like for your equipment… oh, that is right, you will not find any… it’s all budget stuff.
