Our price £3,795 (RRP £7,795)

There is a definite warmth of presentation, a fuller lower midrange sets  up the YBA’s sonic texture. The sound is based on proximity and  immediacy. What sounds the most beautiful is the instruments and vocals  located in the middle of the frequency range. Yet this occurs without  limiting everything to just the midrange. The treble has an open, strong  character, with plenty of energy corresponding to the higher registers  of the vibraphone, drum cymbals, etc.

Several things distinguish  the PRE550A from other digital/analog preamps. It is possible to turn  off the digital section when playing an analogue source. The analog  section has three inputs — one balanced (XLR), one unbalanced (RCA), and  one video pass-through (RCA). There are two sets of RCA outputs and one  set of XLRs.

There is a wide choice of digital inputs — I2 S  (RJ45), AES/EBU (XLR), S/PDIF (TosLink, coaxial, BNC), and USB – plus  there is a network input (RJ45) that accepts signals from a 10 or  100Mbps network. Built-in Apple AirPort Express support enables the  PRE550A to work via a wireless AirPort Express network. It has a direct  input for an Apple iPod or iPhone that bypasses the Apple’s internal DAC  and uses only the PRE550A DAC. There’s also an S/PDIF output jack,  should you want to send a digital signal to another component.

The  asynchronous USB 2.0 connection for a computer requires a driver if  you’re running Windows, but not with a Mac or Linux computer.
