SPL Phonitor XE Headphone Amplifier (Red)

The SPL Phonitor XE Headphone Amplifier is the nonplusultra standalone headphone amplifier without any compromises. With VOLTAiR technology the Phonitor XE is one of the best headphone amplifiers of our time!

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.

Milled from solid aluminum
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.

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! (optional)
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.

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 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.
