A sound stage is meant to be panoramic and the Passion IA350A fills the room. The separation of the channels gives us a wide sound scene yet does not go beyond the surroundings of the loudspeakers. The Passion IA350A adapts superbly to the dimensions of the listening room, but also to the speakers. The dynamics allow us to listen serenely and absolutely to all styles of music under all conditions.
Staying with the uncluttered style synonymous with YBA, the front panel has simply an input and volume selector. The turn on switch is cleverly concealed beneath the front left hand side of the amplifier.
The source selector toggles between many different inputs – both analogue and digital. The digital inputs include an S/PDIF (75 Ohm) Coaxial digital input, a USB (24/192KHz) plus AES/EBU, I2 S, and iPod, all of which receive digital signals from separate digital components. The analogue inputs include 2 RCA and 1 Balanced. All digital inputs automatically adjust to any of the standard digital-audio data-rates from 16/44.1Khz to 24/192Khz. There is one pair of RCA speaker outputs.
It is possible to switch the power to the digital section off completely if your wish is to listen at times to purely analog. The Passion IA350A also has a pre-out bypass feature, if, for example, you wish to connect an active subwoofer or active loudspeakers.
