This pre amplifier is packed full of features and with its amazing array of inputs, you can be safe in the knowledge that this will not be outdated any time soon.
The front panel has just traditionally YBA designed switches controlling the phase and mute operations. The phase switch generates a 180º phase shift between the input and output signals. There are two remaining controls - one for volume one for input selection. The display, again a traditional YBA design, is both elegant and informative.
The rear panel highlights all this product has to offer. There are the standard analog input and output features you would expect in a high class pre amplifier with both RCA and balanced connections. In addition the 550 provides 7 digital inputs, along with Ethernet connection. AirPlay is also available.
With two Cirrus Logic CS4398 DACs on board it is of course ideally suited for use with the Passion CDT 450 CD Transport. To use your PC as a sound source with the Passion PRE 550, you will need to download a driver.
