Spukta It's a USB to SPDIF converter. It receives data from your computer/tablet/phone using USB Audio 2 protocol, converts it to Spdif signal which goes to your DAC. You need this if your DAC doesn't have a USB input, or it's USB input isn't the the best quality. Schiit Eitr does the same. Singxer F-1 implements the latest XMOS chipset, providing the best possible sound quality. There is a catch though: you can buy it directly directly from China for $180, shipped immediately. So why would anyone buy it for $190 here and wait more than a month for delivery?
PTamasThank you! Sounds interesting. About the fact that it's cheaper somewhere else - there are many products that also are cheaper somewhere else, but for me massdrop is more for products that otherwise don't ship to my country or are unavailable anywhere else.
PTamasAdding to what PTamas said, it looks like the Schiit Eitr goes up to 24/192 PCM and doesn't do DSD, whereas the Singxer F-1 XMOS XU208 (according to the description on Massdrop) accepts up to 32 bits PCM going in (stepping down to 24/192 going out) and does do 'single-rate' DSD (i.e. standard SACD quality) up to DSD256. The other thing I've noticed is Schiit says their Eitr is Windows 10 compatible whereas Singxer makes no such claim for their USB interface. Lastly, Schiit is made in the USA whereas Singxer...PRC.
velo_sometimeWindows 10 now has native USB class 2 support, being one of the latest xmos chips I highly doubt one will have compatibility issues. The drivers aren't as complex as they were when trying to work around UAC 1.0 crud in the older days of Windows. As always, buyer beware.
