The Flagship Command Hub for Audio Purists and Studio Monitors
The SPL Phonitor x + DAC768xs is engineered to be the definitive centerpiece for modern high-end audio setups, satisfying both premium headphone listeners and speaker-based studio mastering setups. Operating simultaneously as an uncompromised high-power headphone amplifier and an elite two-channel analog preamplifier, it allows you to switch between headphone and speaker arrays instantly via a front-panel toggle.
By embedding the high-performance DAC768xs processing card directly into its analog mainframe, the Phonitor x bypasses standard external digital conversion bottlenecks. It acts as a premium, low-jitter destination for high-resolution streamers, digital workstations (DAWs), and computer rigs. Free from integrated operational amplifier chips that bottle up micro-dynamics, the Phonitor x handles digital decoding and analog voltage drive with absolute acoustic transparency.
Product Description
The Power of 120V VOLTAiR High-Voltage Architecture:
The breathtaking realism of the Phonitor x is rooted in SPL’s exclusive VOLTAiR technology. Running on a high-voltage plus/minus 60V DC internal power rail network—delivering four times the electrical operating threshold of standard consumer and pro-audio gear—it unlocks unmatched dynamic range and linear performance. Transients develop naturally without artificial compression, and distortion ratings drop to a nearly unmeasurable 0.00085%. This creates an extraordinarily quiet, deep background that exposes subtle acoustic details, spatial room cues, and delicate instrument texturing.
The Phonitor Matrix – Loudspeaker Simulation on Headsets:
Traditional headphone listening creates an artificial, left-to-right channel isolation that leads to rapid mental fatigue and skewed soundstage perceptions. The Phonitor x elegantly solves this with its analog-domain Phonitor Matrix:
Crossfeed Control: Corrects the "super-stereo" effect by simulating interaural level differences, mimicking the natural sound-wave bleeding that happens when listening to speakers in an open room.
Angle Control: Configures the simulated spatial positioning of the audio soundstage, recreating classic studio monitor alignments.
This purely analog circuit moves the music outside of your skull, painting a precise stereo image in front of you that lets you mix, master, or enjoy music for hours without fatigue.
The factory-installed DAC768xs module utilizes the highly acclaimed AKM AK4490 Velvet Sound™ premium chip architecture. It effortlessly translates high-resolution PCM streams at 32-bit depth up to a blistering 768 kHz, while natively decoding Direct Stream Digital signals up to DSD256 (DSD4) over asynchronous USB.
The analog outputs are incredibly versatile. The front panel features a standard 1/4" TRS headphone jack alongside a heavy-duty 4-pin balanced XLR array, sending up to 5 Watts of power per channel into reference dynamic or planar magnetic headphones. On the rear panel, dual balanced XLR and gold-plated RCA outputs stay hot simultaneously, allowing the unit to integrate perfectly as a reference line preamp with active studio monitors or high-current power amplifiers.
Exquisite Industrial Craftsmanship:
Every tactile point on the Phonitor x underscores its hand-built German lineage. It features a solid 45mm aluminum volume dial connected to a premium motorized ALPS RK27 "Big Blue" analog potentiometer, delivering a smooth, high-precision feel.
Universal Remote Learning: The motorized volume system can learn commands from any standard infrared (IR) remote with a quick, one-button setup.
Mechanical VU Level Meters: Two vintage amber-backlit VU meters bounce dynamically to indicate incoming levels. When the unit is muted, the meters glow red to show output status.
Laterality Balance System: Provides an extremely fine-grained balance correction potentiometer to smoothly fix channel level imbalances.
