Why not develop MUETA® for a digital input?
Some people believe that keeping the signal digital all the way from the source (a CD for example) to the amplifier is the way to go. But we have experimentally demonstrated that we can get much better performance by placing the Digital-to-Analog converter in front of our amplifier stage rather than actually in the amplifier stage itself. In the analog domain, you can work much faster then in the digital domain therefore producing more realistic sound quality. It really does not matter where you place the Digital-to-Analog converter. If you have to place it somewhere, we recommend that the best place is in front of the amplifier stage. This way, all feedback loops can be analog and hence real time.
