Tried both for 30 days. Kept the dAck!. I did not compare the two. I DID compare the Benchmark with a Birdland ($1700) and my trusty (rusty) JVC XL-Z1010, level matched and blind. Couldn't tell a dime's worth of difference, nor could 2 audiophile friends. The dAck! seems to be smoother, maybe it's colored, I don't really care. I liked it and the price was right
