Purchased together with the Audiophonics LPA-S450ET. Since the power amplifier has a balanced architecture, when used with older CD players or DACs that only have RCA outputs, an unbalanced-to-balanced conversion via electrical circuitry is necessary. In that regard, this device is essential for bringing out the full performance of the Purifi module and offers outstanding cost-performance.
The sound quality is warm, with the high frequencies extending naturally into the air range. The MUSES electronic volume control is also truly excellent!
However, for those who especially prefer a tight and direct sound, directly connecting a source device with built-in preamp functionality to the power amp via XLR may be more in line with their preferences.
