these guys are at least releasing new firmware but they arent doing that great a job with a lot of mass brickings
mine upgraded fine
the big star is that the cutoff now actually works
you can do 50-300hz in 1 hz increments (!)
so in my setup it will send sub 50hz to your sub or whatever number you want and it was send to the rest to your speakers
the unit actually does so sound good as a BT receiver... you pair it with phones and it does stream quite well... they were smart enough to stick in a chipset that has all the modern codecs
AND it does also stream output to BT headphones quite well too
but that's all it does well
it does not work all that great as a usb dac, nor is the phono that great and the input is busted given its all digitised but hey i mean an $80 preamp... yeah
