This time we did it better
DX7 Pro+ uses ESS SABRE ES9038PRO, with 32bit Hyer-steam architecture, achieves ultra-high performance in the audio field. Each channel of the DX7 Pro+ will be arranged in parallel by 4 conventional balanced channels. This makes the performance of DX7 Pro+ even better.

Descriptions:
>Brand New I/V conversion
Abrand new I/V conversion circuit is designed for better quality audio reproduction. The unique circuit design provided lower distortion, lower noise while occupying less space. The new circuit is pushed close to the limit of physics so that we are able to squeeze out the last bit of performance of the DAC chip.
> Close to physical limits
The ability of DX7 Pro+ to restore music has reached to THD+N<.00006%. That means more and clearer details you can hear.
> Brand new design
The new family-style design that has won IF, reddot and Goldenpin awards on DX5, combined with aluminum precision CNC technology, makes DX7 Pro+ a better part of your desktop.
>Built-in NFCA Headphone amp
The new DX7 Pro+ has the NFCA circuit optimized for this unit, giving the ultra low noise and distortion. It pairs with high sensitivity IEMs and power hungry high impedance headphone nicely.
> DX7 Pro+ has 3 output headphone jacks of 4-PIN-XLR, 4.4mm and 6.35mm to meet different usages.Besides, with the help of 2 gain setting, DX7 Pro+ could reach even wider adaption of different headphones.
>Step volume control
The encoder makes the step volume control more accurate and convenient. Even if the voulume is adjusted to a small voulume, there will not be any channel balance problems.
>Multiple output mode
By double-clicking the volume knob, you can choose from for output modes: "Headphone Amp", "Headphone Amp + Line Out", "DAC", and "Pre-amplifier" to adapt to more application scenarios.
> Selectable output
DX7 Pro+ has balanced XLR output and single ended RCA output. You can choose "XLR only, "RCA only" or XLR+RCA" output for different applications.
>IIS input supports up to DSD512 native
When there is a better unterface, you can the HDMI cable to directly send the IIS signal into the DX7 Pro+'s ESS9038PRO for better decode. IIS inout can support up to PCM32bit768kHz & DSD512native. The IIS inout provides phase settings, DSD channel settings, and DSD indicator pin delection settings, which are compatible with most digital interfaces on the market that use the HDMI interface to output IIS signals.
This function usesd only HDMI interface to transmit IIS signal instead of the standard HDMI signals. Thus it cannot be used for HDMI interface of the PC,TV,and set-top box.
>Plug and play turn your PC into a HIFI source
DX7 Pro+ has a wide range of compatibility: Windows 10 and above, MAC, Linux,IOS,Android can be plug and play. DX7 Pro+ uses 2nd generation 8 core XMOS XU208, USB supports up to PCM32bit768kHz and DSD512 native.
