Perreaux 255 i - Eloquence
Panoramica prodotto
The 255i is Perreaux's most powerful, most sophisticated integrated amplifier. It's performance and specifications are truly impressive, but hearing the 255i is when you will truly appreciate the quality engineering, design and craftsmanship. The 255i is the most advanced integrated amplifier Perreaux has ever produced.
Optional internal 32-bit/384kHz Digital to Analogue Converter (DAC) and Moving Magnet/Moving Coil (MM/MC) Phono Preamplifier modules ensure complete integration of digital source components (such as network music servers and set-top digital receivers), as well as turntables, into a high-performance system.
