I bought the Sprout100 as a replacement for my Teac AI-101DA-B due to a number of issues; sporadic volume change between the remote and knob, sporadic delay over USB, the USB device driver only works at 24-bit 32kHz, and the 26W per channel wasn’t enough for my speakers.
I couldn’t find another replacement that fits on my desk and has all the features that I wanted until I saw the Sprout on Z-Reviews. (Shoutout to Zeos.)
The Sprout100 supports more inputs (vinyl) than the Teac, four times the output power over the Teac, headphone support with 1/4’ input, a working USB device driver, and US based support. I’m solded.
I have been listening all weekend and I love the new sound.
