Not that I'm aware of, but what updates would it even need? It was so far ahead of it's time, I'd buy it today happily. Seems like other brands are only just finally starting to offer units with similar options and capabilities of that STR. That one will be a tough act to follow on an update in my view. A new (better?) DAC no doubt, but that's more marketing than anything audible as we have had transparent DACs for decades now. I'm not audio engineer, but seems to me going to be tough to improve on beyond some minor tweaks.
