Devialet200 Headphone Amplifier connection through Magic Wire Dac

[Gomiki]

Normaly the maximum input line level of any amplifier is 4 or 5 Volts, although the normal level is 2 volt.  If you say to connect directly the Devialet output  speaker to input headphone amp,  , I think it is not a good idea, even if it goes down to the minimum (30 w) the exit of the Devialet I think would be dangerous. What if I could (I've tried, but in the end I never did) is to connect the headphones directly to the speaker output, for this you only need an impedance adapter box. HIFIMAN has one for its Hifiman HE-6 and other  low efficiency Hifi headphones. I have a 200 ohm LCD-4 that I think would work great with this adapter,  even directly ( I ask the Devialet support) and they told me that Devialet hardware is prepared to work with those impedances, but they strongly urged me to lower the output (30w) to the minimum and start with the volume to the minimum before try.

Anyway the DAC integrated into the headphone amplifier itself will give you maximum performance, I tell you why I have a Moon 430HAD with a built-in  ESS Sabre 9018K2M chip and sounds much better than with the line input from the Devialet Pre Out Wolfson.
