Since this was my quote I’d like to disagree with accuracy and realism being the same. This is particularly true when music isn’t being played back at ear bleeding volumes. A great example is the upright bass. If you’ve ever heard a bass in person, it has a particular sound quality even at lower volumes and you can feel a thump in your chest. Most systems I hear that are neutral (for instance Wilson speakers with Spectral electronics) don’t provide this energy at reasonable volumes.
Most systems I’ve heard that are very high end (over 200k) lack emotional connection for me. I perform music professionally so I know what real instruments sound like when live. This is similar to why many people prefer tube gear. For vocals, tubes can (but don’t always) add just a little color that to me makes the voice sound more real and less like a recorded and reproduced version of the same thing.
