What can this product do for you?
Upgrade existing system: connect the amplifier to the preamp-out of your existing home theater receiver to experience a new level of stereo listening. Requires an extra pair of loudspeakers or speaker switch.
Combine with Cyenne Audio DAC: The 5 and the 3 series of DAC can be directly connected to the power amplifier for the best possible sound. No need for pre-amp.
- To replace existing end-amplifier: Is easy as cinch connectors are available.
