Does the power supply make a difference?
Sure. I grabbed one of the high-power generic switching supplies Allo had given me in the past. At first it generated a lot of power supply noise but then discovered a ground terminal underneath Boss2. Once I used that to ground it to my Audio Precision, all the noise went away. Seems like by default the device is floating. Likely this would have improved the performance with the fancy supply as well (doesn't impact distortions though):Thanks @amirm, great review as always. I understand you measured the Boss2 with the Nirvana power supply. Would you be so kind and measure it again with a “regular” power supply? Just want to see those graphs unchanged. Thank you!
You do not. These streamers are used in "push mode." In a player like Roon, I use my own player and just "beam" the audio to this streamer next to the audio system. Your interface is in side Roon. The device basically makes your DAC work on Ethernet/Wifi cable instead of USB.I like the funky enclosure, and good for Allo that this measures as well as it does, but I have no idea how or why I'd use a device like this.Don't you need a proper screen?
RPI needs at least 2.5A , USB cannot supply that much power .
USB type C can do up to 3A, otherwise it wouldn't be used as the power input of the Pi 4.
Item can be shipped from EU at Allo direct too, thoughEurope
