i had one for home use for a while.
macbook pro->BMC2->adcom 555 -> duntec PCL15s
it sounded fine. better then then using the outputs on my macbook pro directly into the amp/speakers
features were good, didn't like the weird resolution of the gain controller.
it would "snap" to zero when near it.
still, for the price.. its pretty unbeatable in terms of features if only have digital outputs feeding it
