Phonitor xe
Our nonplusultra headphone amplifier.
The Phonitor xe is the nonplusultra standalone headphone amplifier without any compromises. Phonitor Matrix, remote volume control, retro-look VU meter, the optional premium DA converter and the all-superior VOLTAiR technology make the Phonitor xe one of the best headphone amplifiers of our time.
Great sound – 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 pin XLR plug.
Thanks to the enormous output power, all headphones are driven effortlessly.
Thus, it plays out the advantages of the SPL VOLTAiR technology and rewards the listener with an honest, detailed and at the same time vivid sound experience.
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.
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.
Source of joy
Up to six (6 !) stereo sources can be connected to the Phonitor xe:
XLR, RCA and via the optional DAC768v2 also USB, COAX, OPTICAL and AES.
Phonitor xe accepts almost all audio connections. Balanced via XLR or unbalanced via RCA connectors.
With the optional DAC768v2, four additional digital sources are added. From USB to professional AES format, no wishes remain unfulfilled.
The DAC automatically picks up the sampling rate and resolution of the digital playback source. No matter if a streamer, computer or CD player is connected. No further settings on the Phonitor xe are necessary.
DAC768v2 – the SPL reference DAC in the newest revision!
The highly acclaimed AKM AK4493 SEQ VELVETSOUNDTM premium DAC chip is used as the converter chip in the digital/analog converter within the latest version of the SPL DAC “DAC768v2”, which thanks to its architecture reproduces the finest sound details. It impresses with even lower distortion characteristics and a wider dynamic range than its predecessor.
It converts PCM audio with a resolution of 32 bits and a sampling rate of up to 768 kHz, which is equivalent to 16 times CD resolution. Direct Stream Digital is also supported up to a resolution of DSD4 or DSD256. The DAC768v2 features the newest version of the Spartan FPGA – Spartan 7.
In contrast to the smaller SPL DAC “DAC768xs”, it not only offers an AES/EBU digital input, but also the new, optimized SPL SLP120 with VOLTAiR technology.
The SLP120 (Super Low-Pass)
The analog output of the DAC chip must be filtered by a low pass filter. 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. The filter specially optimized for the new SPL DAC768v2 is called SLP120 (Super Low-Pass).
The optional DAC768v2 for the Phonitor xe is equipped with the SLP120 – an analog “Super Low-Pass” filter with VOLTAiR technology.
DAC768v2 – what’s new:
1. AK 4493 SEQ
The DAC768v2 is equipped with the latest generation of the premium DAC chip – the AK 4493 SEQ – from Asahi Kasei (previously AK 4490).
The AK 4493 SEQ impresses with even lower distortion characteristics and a wider dynamic range than its predecessor.
2. Spartan 7
The DAC768v2 features the newest version of the Spartan FPGA – Spartan 7 (previously Spartan 6).
3. The newest generation of the SPL low-pass filter “SLP120”
The DAC768v2 comes with a completely new tuned low-pass filter, which perfectly matches the sonic strengths of the new converter chip. It ofers an even better representation of the stereo image as well as a three-dimensionality we never experienced from any other DAC before.
The new DAC revision can be recognized by the “DAC768v2” label on the serial number sticker.
The design of the DAC768v2 is unfortunately not compatible with devices that were built with DAC768.
In addition to the original DAC chip (previously AK4490, now AK4493), other components in the digital environment that are no longer available, such as the previously used version of the Spartan-6 FPGA (now Spartan-7), had to be updated. As the technical characteristics of these components are different from those of their predecessors, further technical adjustments had to be made to the device in order to achieve the best possible sonic performance of which SPL is known for. The analog low-pass filter with 120V technology is also different in the devices with DAC768v2.
It is therefore not possible to simply replace the DAC768 module with the DAC768v2 module.
Good ol‘ times
Two mechanical VU meters visualize the input levels for the left and right audio channel.
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.
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.
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.
The 120V technology achieves exceptional technical specifications and sonic benefits. Technically, in terms of dynamic range, signal-to-noise ratio and headroom. Sonically, in terms of richness of detail and an absolutely relaxed listening experience.
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.
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 12 dB 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.
