I have no idea. I'm using the Rokk's in my home office, using a NAD monitor series receiver and CD player, and an Oracle Alexandria turntable. Even with modest supporting gear, the Rokk's sound really good to me. Point of reference is my main system, Oracle Delphi Mark IV, YBA CD player, two Classe Audio amps, Martin Logan ReQuest speakers. Now, the two don't compare, but I do know good sound...
