The Passion PRE550MKII by YBA is a high-end preamplifier and DAC designed for audiophiles seeking versatility and sonic purity. It features a fully balanced architecture and supports PCM up to 32-bit/384kHz and native DSD256, making it ideal for high-resolution digital playback. With built-in streaming capabilities via Ethernet and USB, plus support for UPnP and DLNA, it serves as both a control center and a digital hub for modern Hi-Fi systems.
Encased in a brushed aluminum chassis, the PRE550MKII combines elegance with functionality. The front panel includes a signature oval display and rotary control, while the rear offers a wide array of inputs: USB, AES/EBU, Coaxial, Optical, BNC, and HDMI I2S, along with analog RCA and XLR. Outputs include balanced and unbalanced analog, plus digital passthrough. Internally, suspended transformers and optimized circuit geometry reduce vibration and signal path length, enhancing clarity and realism.
Designed for audiophiles who demand precision, flexibility, and musicality, the Passion PRE550MKII is the ideal partner for YBA’s Passion AMP650 or other high-performance amplifiers. Whether decoding high-res files or anchoring a full analog/digital chain, it delivers immersive sound and intuitive control. The box includes the preamplifier, power cable and remote control. The unit measures 430 x 412 x 118mm and weighs 12 kg.
The Passion Series AMP650, PRE550 MKII and CD430 MKII offer balanced XLR I/O using balanced stages for low‑noise, long‑cable transmission; for quiet home systems with short interconnections, their RCA paths are often preferred because the single‑ended implementation can deliver lower cross‑distortion and better impedance matching for a clearer, more natural sound.
