Overview

Prelude-5 is a high-resolution vacuum tube DAC that supports DSD 512, DXD 352.8 kHz and PCM 32Bit/384 kHz. All digital inputs are electrically insulated to support digital input ports for USB 2.0 and 3x SPDIF inputs, which are free from noise. The true balanced XLR and RCA analog outputs are tuned through a vaccum tubes. Typical DAC's with semiconductors applied to analog outputs have the advantage of relatively cheap prices but have a tendency to produce "dry" sound. Prelude-5 is designed for analog output stage using the "Quadruple Mono" method. The transparent musical pleasure of the Triode, and the light of the vacuum tube additionally provides visual pleasure as well. In particular, the USB input has been designed to be insulated to prevent digital noise caused by power-ground imbalance. Impulse noise from the peripherals power on and off also blocks the inflow path. Especially, if you connect your CD player's optical or Co-axial digital signals to input of Svetlana-4 you can experience a new world that is upgraded to a high-end vacuum tube CDP. Prelude-5 is a fully balanced, non-feedback design that delivers high speed and wide band frequency characteristics, excellent in linearity and triode A-class operation playing delicate analog sound without white noise.
