The benchmark dac is the same way. Take a look at how many you see used. Look at a hot review in Stereophile or the TAS on a piece of equipment and you'll see a lot of discussion on it and then it'll fade away and start showing up in the used section - see also Zu Adiagio - I could go on and on - Creek 5350 - Gallos - NAD - not to say these aren't good components but don't get carried away.
