FX-Audio DR07

[onethreetwowaitthatswrong]

FX-Audio DR07, looks like a relatively cheap Dac & headphone amp combo, but still on the higher side of the Fx-audio line at 145€ :

DAC chips	2x AKM AK4493
Bluetooth receiver	Qualcomm QCC5125
USB receiver	XMOS XU316

SNR	120dB
Headphone output power	2x 1100mW @ 32Ω

RCA output level

2.5Vrms

Rest of the specs can be found here or there for example. Interestingly, it includes an optical output, and combines jack 3.5 and 6.35mm headphones outs.

I ordered it and sent it back soon after.

Sound itself was absolutely fine but there were a couple of issues in my use case :
- No pure dac mode with fixed output volume -> having to be careful when switching from dac to headphone amp to not blow your ears
- loud click at every track beginning and end in usb and bluetooth
- manual below bare minimum

The click was the most annoying, but might depend on the source. Anyways, was not for me.

That's the thing with a lot of DACs... they all measure well and sound well but it is functionality, support, compatibility, connectivity, operation, size and 'behavior' (other than sound) that determines if a DAC/amp is usable in certain occasions/conditions.

For instance they should bundle an electronic microscope to read the volume level on the display, but in the end who cares, sample rate is much more useful when you risk to blow your ears...
