Among the best DACs in the world

Audio-GD is evolving its range HE, composed of its most high-end products. They have the longest design and testing time since the brand's inception.

This model R2R 7 HE now has 4 Ladder DAC DA-7 R2R fully symmetrical and discrete, allowing support of DSD and PCM 32Bit / 384kHz in the best way.

The new FPGA (Field-Programmable Gate Array) processor used is the same as that used in very high-end DACs, such as the popular ROCKNA WAVEDREAM DAC. Your DAC R2R 7 HE can always be updated at the firmware level, and therefore never be obsolete.

The HE range offers a more detailed sound reproduction, a greater dynamic range, and a wider and deeper sound stage.

Flawless components and connectivity

Like its predecessors, the Audio-GD R2R 7 HE uses the brand's Amanero USB technology supporting resolutions up to 32bit / 384kHz.

The R2R 7 HE has 6 inputs: BNC / RCA Coaxial / Optical/ HDMI I2S / RJ45 I2S / USB. Each is equipped with the right interfaces to offer the highest sound quality. On the output side, the R2R 7 HE offers XLR, RCA and ACSS.

Each product is tested with professional equipment, the Audio Precision SYS-2722, to ensure maximum quality and reliability.

A largely improved DSP

The great novelty of this R2R 7 HE is probably its brand new DSP and its special design. It is a two-channel digital interpolation filter and a data processor for digital audio. This DSP offers advanced features for high performance applications up to 450MHz. The DATA and Master-Clock processing is done without jitter. Thus, this HE-7 covers a wider sound stage and allows you to enjoy precise and neutral sound reproduction of your files. The DSP also avoids digital noise.

A food of size

If the 4 DA-7 R2R and the excellent analog output stage impress on this R2R 7 HE, it is not left behind on the power side, far from it. Indeed, to ensure optimal operation of the DAC and to promote sound reproduction, there are no less than 21 power units that feed the device. 19 high-quality PSU class A parallel groups and a dedicated dual-stage DC block allow the HE-7 to provide its own power supply for deep, neutral feedback. The dual stage PSU is particularly important for digital components, to keep the jitter low and not degrade your music.

Froms, Audio-GD integrates the "Power Regenerative" technology in its R2R 7 HE-7 to block power line interference. In this system, the AC signal is first converted to DC and then regenerated to produce a perfect sine wave.
