Phonitor SE:

• Positioning: Entry-level headphone amplifier and DAC in SPL's Professional Fidelity line.
• Description: Features SPL's Phonitor Matrix crossfeed technology that simulates speaker listening through headphones, making it unique among headphone amplifiers in this price range. While the Elector focuses purely on analog preamplification and the Performer S1200 delivers raw power, the Phonitor SE bridges the gap by offering both headphone amplification and digital conversion in a compact package designed for desktop use.

Phonos Duo:

• Positioning: Professional phono preamplifier designed for both moving magnet and moving coil cartridges.
• Description: Delivers up to 70 dB of preamplification using SPL's 120V VOLTAiR technology, making it one of the most powerful phono stages for low-output moving coil systems. Unlike the Elector which handles line-level sources or the Phonitor SE which focuses on headphones, the Phonos Duo specializes exclusively in vinyl playback with both balanced XLR and unbalanced RCA connections for professional and audiophile applications.

Crossover:

• Positioning: Active analog crossover for bi-amping and subwoofer integration in high-end audio systems.
• Description: Provides fully analog frequency division to avoid unnecessary digital conversion, setting it apart from the digital crossovers commonly found in consumer subwoofers. While the Performer S1200 amplifies the full frequency range and the Elector manages source selection, the Crossover allows precise frequency management between drivers for users seeking to optimize multi-driver speaker systems or integrate subwoofers without digital processing.

Elector:

• Positioning: High-end analog preamplifier serving as the control center for audiophile systems.
• Description: Features six inputs including three balanced XLR connections and operates with SPL's 120V rail technology for exceptional headroom and low noise. Compared to the Phonitor SE's focus on headphones or the Phonos Duo's vinyl specialization, the Elector serves as a comprehensive analog hub with tape monitoring and remote control for users with multiple high-end sources who prioritize pure analog signal paths.

Performer S1200:

• Positioning: Flagship stereo power amplifier in SPL's Professional Fidelity lineup.
• Description: Delivers 520 watts per channel into 4 ohms using SPL's proprietary VOLTAiR technology, which maintains optimal performance across all frequencies through separate voltage and power stages. Unlike the source-level components in the lineup, the Performer S1200 provides the muscle to drive any loudspeaker with authority, featuring input sensitivity trim controls and both XLR and RCA inputs to match perfectly with the Elector preamplifier or other high-end sources.
