Are all asynchronous USB inputs similar?

Steve, I'm with you, if computer sound card audio was better I would think more than one vender would use it. The USB is more convenient and you can use any computer you have in your house. I personally am not interested in trying the one product offered.

To be fair (unlike cerrot), Bryston uses a Juli@t PCI card in their server with very good results, although not quite as resolving as the best USB IMO. I thought their system at RMAF was better than any other all-one-manufacturer system. They even have their own speaker now.

For sake of accurate information in this interesting discussion, there's no sound card for the Baetis as it's directly connected to the mother board. I agree with the convenience of USB but that doesn't necessarily correlate to superior sound, two different arguments. It's good to have choices among high quality offerings.
Charles,

We can all see the original question. While I posted my usual, smug, remark, the responses (thanks, Charles), did conjure up some nice discussions (finally), where there's finally talk where the USB interface may just be more convenient than better sounding.

Happy to be a part of it.

OK, some excellent responses here. My reason for the question was that I currently have an Auraliti PK90 sending USB to a Blacknote DAC30 which has async USB. It's a few years old now, and with the digital world that's more like a decade. So I was wondering if the newer (and cheaper) USB dacs were passing it by, or were they designed with the same technology? Thanks everyone.
