ROMA 41DC+ / 41DC Headphone Amp



Roma 41DC/41DC+   All tube A class Headphone Amp

Synthesis is set to release a new headphone amplifier which supplies 2W in a pure class A arrangement using an ECL82/6BM8 in a Single Ended configuration. The Roma 41DC+ has been principally developed to drive high power headphones most coveted by audiophiles for their excellent soundstage. It has line, USB (PCM up 32Bit/384KHz, DSD up to 5,6MHz) and optical inputs as well as an output connection for speakers. The power amp also features a patented adaptive output technology (BLS) that automatically sets the output tap depending on the headphone load.
