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.

Great Sound –
for all headphones

The Phonitor xe is the nonplusultra standalone headphone amplifier without any compromises. Phonitor Matrix, remote volume control, retro-look VU meter, premium DA converters and the all-superior VOLTAiR technology make the Phonitor xe one of the best headphone amplifiers of our time.

Twice as nice

The Phonitor xe provides headphone outputs on the front and on the rear. On the front, you switch between F (front) and R (rear). This way, your favorite headphones remain firmly connected on the rear – without visible cabling on the front.

“With the Phonitor xe, SPL delivers the ultimate device for all headphone enthusiasts, who value neutrality, preciseness and control, combined with great musicality.”

Dr. Martin Mertens

Milled from solid

The massive 45mm volume control knob milled from aluminum is a haptic highlight. Its mass together with the motorized Alps RK27 “Big Blue” potentiometer enhances the “spoon in the honey” feeling even further.

The red marker LED ensures good visibility of the volume parameter even in darkened environments.

Remote control

The volume control can be remotely controlled with any infrared remote control.

The Phonitor xe learns to communicate with it with the simple push of a button.

Learning made easy

Using Phonitor x as an example, this video explains how you can use any infrared remote control to remotely control the volume.

“The fineness and transparency with which the music is depicted is just awesome – what a richness of detail!”

Source of joy

Up to six (6 !) stereo sources can be connected to Phonitor xe:
XLR, RCA and via the optional DAC768 also 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 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. In contrast to the DAC 768xs, the DAC768 not only offers an AES/EBU digital input, but also the SPL DLP120 with VOLTAiR technology.

The DLP120 (Dual Low-Pass)

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.

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 and sound.

“How does the device sound?
Let’s erase all doubts right away:
it sounds fantastic!”

HiFi Statement

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. This switch also activates the laterality control.

“On to the meat of the review though,
how does the Phonitor xe itself actually sound?
To be honest, it’s spectacular.”

The Revolution: Phonitor Matrix

The Phonitor Matrix is the revolution in the headphone amplifier.

Thanks to the Phonitor Matrix, music can be experienced on headphones as if it was played on speakers. The tiring super stereo effect is a thing of the past.


Enjoy their music without listening fatigue and exactly the way it should be heard.

Music is normally produced and mixed for playback on stereo speakers.

Listening on headphones is different from listening on loudspeakers. The biggest difference is the lack of crossing signals of the sound signal from the left speaker to the right ear and from the right speaker to the left ear. These crossing signals are missing in conventional headphone listening, because there are no signals crossing from one side of the headphones to the other. This results in an unnaturally wide stereo image and the various sound sources of the audio signal are not localized as the sound engineer intended them to. This effect is often referred to as “super stereo effect”. During conventional listening on headphones, our brain can balance the false representation of the playback to a certain extent – but this is very exhausting.

The SPL Phonitor Matrix can correct this false stereo image with an analog circuitry. The Phonitor Matrix therefore not only ensures a correct representation of the stereo image, but also a relaxed listening experience.

The two main parameters of the Phonitor Matrix are Crossfeed and Angle:

Crossfeed determines the crossing signals of the channels, the so-called interaural level difference.
Angle determines the opening angle of the stereo image, the so-called interaural time difference.

Crossfeed

Level and frequency adjustment of the right (red) and left (green) audio channel at maximum crossfeed.

Angle

Settings for the speaker placement angle to determine the interaural time difference.

“One way or another, the purchaser of a Phonitor xe receives a reliable high-end solution, which not only drives every kind of headphone on the market without any effort, but also convinces through useful and rare extras like the, in my opinion, still unrivaled crossfeed circuit.”

Sounds good!

With all devices of the Professional Fidelity series we develop not only according to plan, but also by ear. All important components are installed on the circuit boards using Through-hole technology. This way we can ensure that we can use the best sounding components.

The VOLTAiR Technology

The 120V technology is our reference technology. The 120V technology is unique in the world. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps. In our Professional Fidelity series, we refer to this unsurpassed technology as VOLTAiR technology.

The highest possible audio quality requires the highest possible audio operating voltage.

The 120V technology works with +/-60 V. To be able to handle such a high voltage, we have developed special proprietary operational amplifiers that can operate with a DC voltage of +/-60 V: the SPL 120V SUPRA operational amplifiers. 

This high voltage would destroy conventional components and operational amplifiers.

By the way, the “120V” in the name of the technology has nothing to do with the local mains voltage from the mains power socket. This is about the operating voltage inside the device with which the audio signals are processed.
The mains voltage from the mains power socket is transformed to the required secondary voltage in the device’s internal linear power supply with toroidal transformer. Rectifiers convert this AC voltage into DC voltage required in the audio device.

VOLTAiR is a composition of the terms Volt and Air.
Volt is the unit for electrical voltage and Air stands for the unlimited space the music can breathe in.

VOLTAiR symbolizes the perceived limitless dynamics resulting from high audio voltage.

What exactly is that?

And what does it do?

Good questions need good answers.

And that’s what the 120V technology (VOLTAiR) video gives you.

Comparison

Most audio devices work with an internal operating voltage of +/-15 volts and can thus process a maximum input level of +21.5 dBu. If a DAC, for example, has an output level of +22 dBu at 0 dBFS, level peaks of the music material would already cause overloads in the input stage of the device. 

All components in the audio device often operate at their limits. The result is an unsteady sound that causes stress and faster ear fatigue.

SPL devices with VOLTAiR technology can handle input levels of +32.5 dBu thanks to the higher internal operating voltage of +/- 60 volts – thus offering 12dB more headroom. All components consequently operate continuously in the optimum operating range. The result is a very pleasant, natural and relaxed sound experience. So you can enjoy your music in every detail.

These diagrams clearly show the superiority of the VOLTAiR technology in comparison to other circuits with lower, common operating voltages.

Home is where the heart is

That’s why we manufacture all devices in our own production facility in Niederkrüchten on the Lower Rhine, Germany.

VOLTAiR is that good

In the lab, we pitted Phonitor xe against the best audio measurement system and found that Audio Precision could not measure VOLTAiR technology.
