I own the HiFi Rose 150b and I’m a fan. The features I really like include the apps to tune in global radio stations, and the ability to stream 4K YouTube to a nearby television, while playing the audio, typically concert footage, through my system. I also really like the large display, and I find the menus to be intuitive and helpful for using the device and setting it up. I find I use the remote control app more than the remote control itself, but both are fine. If you’re buying it because of the meters, don’t, I find them more of a distraction and typically don’t display them.
As for the sound quality, I’m not the type of audiophile who can provide a lot of flowery descriptions. Though I will say the sound is very clear and detailed. For my tastes, I like things on the warm side, and while I think my overall system has something to do with this, the sound from the 150b is brighter than my analog, and I am looking to tame that. I’ll be looking at cables, and maybe putting a tube buffer either in a tape loop or in line with the streamer.
Overall, I’m a satisfied customer
