Really surprising for the price
I bought it without any pretension because it was the best available in the shop, but I'm relatively surprised by such a small and inexpensive DAC! I was worried about poor audio quality, especially as Logitech doesn't say what audio codecs it supports.
In the end I ended up with a product that's really easy to use (just plug it in and it's ready to go) and with very decent audio quality, without of course claiming to be HiFi.
I'm now using it on a 4-channel Pioneer DJM-600 with an InterM L1400 amp behind it and a pair of legendary Electrovoice SX300s in my flat. (A bit too much, I admit, but it sounds great so I like it).
The neighbours will be very happy with this purchase too!
