But after just a small infinity more , there ' ll be absolute freedom . And some more confinement , probably . <| sep |> A single cricket <| sep |> Clinton and Trump <| sep |> And that ' s why they made the event last 7 days , so everyone got the streak bonus . <| sep |> I ' m not using a pi , using one of these , but similar concept . If using the pi , just need the arm version of brutefir . Anything will work really , just wanted something small and low power that was as beefy as possible . N 82 EtelI ' m just using it for an active xover , 3 analog ins , 6 outs for active LCR . You can setup brutefir to take input from anywhere , though I haven ' t done it . There are lots of ways to get the physical IO necessary spanning huge budget differences . I ' m going the USB route . The motu stuff works in linux and the 16 a or 1248 are spectacularly low distortion . I was going to use a 16 a originally , but it has a bit of very high frequency noise that didn ' t play nicely with my switchmode amps . I have 3 hypex dual mono nc 400 s boxes .

I ended up trying the fireface UCX , which has a class compliant usb mode , but wanted something a little nicer so go the UFX . Many have had success using the usbstreamer from minidsp and an adat interface . You can pickup used ones that are pretty nice for cheap on ebay . Someone I know is using an rme adi 8 . There are lots of options there , even behringer has a decent one for cheap . The focusrite scarlett interfaces work in linux as well . I also have an emu 0404 usb that works no problem .
