Phonitor xe

Our nonplusultra headphone amplifier.

Phonitor Matrix, Volume remote control, VU meter in retro look, premium DA converter and the preeminent VOLTAiR technology make the Phonitor xe the best headphone amplifier of our time.

For all headphones

The Phonitor xe offers connections for a standard headphone with a stereo jack plug and for balanced-driven headphones using a 4-pol XLR jack.

Thanks to the enormous output power, all headphones are driven effortlessly.

Twice as nice

If you like to avoid the headphone cable hanging off the front you may want to use the connectors on the back of the Phonitor xe.

The switch on the front selects between the front (F) and rear (R) outputs.

Milled from solid

is the big 45mm Volume control. Its mass together with the motorized Alps RK27 “Big Blue” potentiometer enhances the “spoon in the honey” feeling even further.

The red marker LED makes the setting visible even in darkened environments.

Volume RC

The volume can be remote controlled with any infrared remote control, that the Phonitor xe simply learns.

To do this, press the IR programming button and then the buttons for louder and quieter.

Source of joy

Up to six (6 !) stereo sources can be connected to Phonitor xe:

XLR, RCA, USB, Coax, Optical and AES/EBU

Phonitor xe accepts almost all audio connections. Balanced via XLR or unbalanced via RCA connectors.

With the optional DAC, four additional digital sources can be added. From USB to the professional AES format, no wishes remain unfulfilled.

The DAC768

The highly acclaimed AKM AK4490 Velvet Sound™ premium DAC chip is used as the converter chip in the optional digital-to-analogue converter, which thanks to its new architecture reproduces the finest sound details.

It converts PCM audio with a resolution of 32 bits and a sampling rate of up to 768kHz, which is equivalent to 16 times CD resolution. Direct Stream Digital is also supported up to a resolution of DSD4 or DSD256.

The DLP120

The analog output of the DAC chip must be filtered by a low pass filter. Phonitor xe has two of them: One for PCM audio and one for DSD audio, since different roll-off frequencies are required.

And in contrast to all other DACs in the world, the low pass filters here are built using VOLTAiR technology, which provides a plus in dynamics and headroom.

Good ol' times

Two mechanical VU meters visualize the input levels for the left and right audio channel.

With the VU switch you can optimize the display for different signal levels.

Finding the middle

is not always easy. By our very nature, hearing can be leaning more to the left or more to the right. This is especially obvious when listening with headphones.

That’s why Phonitor xe has the uniquely finely resolved laterality control. With it, the center can be found perfectly.

With the mode switch you can choose between stereo or mono playback. To the right, the laterality control is switched on.

The Revolution

in the headphone amplifier is the Phonitor Matrix, thanks to which you can listen to music through headphones as if you were listening through speakers. The tiring super stereo effect is a thing of the past.

Enjoy your music exactly the way it should be heard.
