Just from listening and owning over 20 really good balanced headphones amplifiers from various makers. Again, I would rate benchmark DAC with headphone amp unit as being very overpriced for the performance that you can get now. Their DACs used to be very good but not any more in today's very competitive matket. The NAD M51 that I used to own easily best their DAC3 in a direct comparison and this is not counting the Yggy. They wrote that article to justify keeping the same bright and slightly harsh headphone amp module on all of their line up. Again, it has been my direct experience with their gears so I just want to counter their claim.
