The maverick is a great piece and considered a wonderful DAC, beating out many other DACs above its price point. It is limited on inputs. I use the optic in for my CD player and to stream music from my Apple TV. I just unplug one and plug in the other. The analog is used for my turntable. My brother and I were doing some serious listening last night and man does this thing sound good. It's surprising the difference in sound you can get by switching out tubes. The upgrades that were made were a better tube and better burr brown opamps from the factory. That took the price from $179 to $229. I like the idea of using this as my pre because it eliminates one more device from the signal chain. You should really give one a shot and if you truly don't like it you'll have no problem selling it.
