General description

DENPO PREMIUM DAC is the smallest representative of digital-to-analog converters in our product range. The device is especially designed to offer a device that offers high quality sound at affordable price. The used ROHM BD34301 (MUS-IC) chip is a product of great japanese chip manufacturer, and it can produce impressive sound quality based on its technical parameters. Finally the sound of these equipments depends on the digital and analog circuits, PSU parts and clock management, dac chip capability. During the development phase we strived to get a great balance between PSU-digital-analog and clock parts, it means in the final sound a huge soundstage, well balanced high-mid and low freqs and natural warmth.

We've been able to develop the dac in a direction that offers versatile use thanks to its small size and seemingly a lot of digital ports to connect with different kind of digital source equipments (like CD transport with SPDIF output, music servers with i2S or USB outputs, TV unit with Toslink optical output).

We recommend it to those users too, whose source device has only USB audio output and would like to minimize the numbers of the digital source devices in the music chain. 

It has balanced and unbalanced outputs to connect to an integrated amplifier or preamplifier. Thanks to the rigid alumium case an RFI shielding to ensure proper panel cooling beside shielding. The analog and digital power supply transformers are wired separately to provide optimal insulation from power lines and sensitive parts.

The dac is available in a silver finished aluminum version as well as black anodized aluminum version. 

All of our DENPO PREMIUM DAC arriving with our own developed full discrete, single Operation Amplifiers (3pcs/channel)

Thanks to the especially selected parts and clock technology our feeling is that we can offer to our customers a warm, fluid, lifelike, airy and smooth sounding digital to analog converter.
