SMSL VMV P2 MK2 99-Op-Amp Parallel Matrix Headphone Amplifier and Preamplifier with PLFC+ Circuit and GaN Power Supply

99-Op-Amp Parallel Matrix: Reference Headphone Amplification

The SMSL VMV P2 MK2 is a flagship fully-balanced headphone amplifier and preamplifier built around an extraordinary 99-piece low-noise operational amplifier parallel matrix. This brute-force yet precision-engineered architecture simultaneously satisfies the high-voltage swing requirements of high-impedance dynamic headphones and the high-current demands of low-impedance planar magnetics — delivering 14 watts per channel into 16 ohms and 8 watts per channel into 32 ohms. With a fully-balanced PLFC+ discrete circuit achieving 0.00006% THD+N, a GaN (Gallium Nitride) power supply delivering 135 dB dynamic range and SNR, three selectable gain levels, Hi-End preamp output capability, and USB firmware upgrade support, the P2 MK2 is a statement of what is possible when no compromise is made in the pursuit of headphone amplification.

99-Op-Amp Parallel Matrix Architecture

Where most headphone amplifiers employ a handful of gain devices, the P2 MK2 deploys 99 individual low-noise operational amplifiers in a massively parallel configuration. This architecture dramatically reduces output impedance while multiplying instantaneous current delivery capability. The result is an amplifier that drives any headphone — from ultra-sensitive IEMs to the most current-hungry planar magnetic flagships — with absolute authority, control, and a noise floor that sits below the threshold of measurement.

14W x 2 into 16 Ohms of Clean Power

Output power is specified at 14 watts per channel into 16 ohms and 8 watts per channel into 32 ohms. These are not inflated numbers — they represent continuous, clean power delivered through the fully-balanced PLFC+ circuit with distortion components buried at 0.00006% THD+N. Every headphone ever made operates comfortably within the P2 MK2's power envelope, with headroom to spare for the most demanding recordings.

PLFC+ Fully-Balanced Discrete Circuit

SMSL's Precision Linear Feedback Circuit (PLFC+) operates across four fully-independent differential channels from input to output, actively canceling common-mode noise and preserving signal integrity. The measured performance speaks for itself: 135 dB dynamic range, 135 dB signal-to-noise ratio, and total harmonic distortion plus noise of just 0.00006%. These are numbers that challenge the finest standalone preamplifiers regardless of price.

GaN Power Supply with 135 dB Dynamic Range

The power supply stage employs Gallium Nitride (GaN) semiconductor technology, which switches faster and wastes less energy than traditional silicon. This translates to cleaner, more stable DC rails with lower noise and faster transient response — directly contributing to the P2 MK2's extraordinary 135 dB dynamic range. The power supply is as much a part of the sonic signature as the amplifier circuit itself.

Three Selectable Gain Levels

Three gain settings allow the P2 MK2 to be precisely matched to any headphone and source combination. Low gain for ultra-sensitive IEMs preserves the lowest possible noise floor. Medium gain for the majority of full-size headphones provides optimal headroom. High gain unlocks the full voltage swing capability for the most demanding high-impedance dynamic and low-sensitivity planar headphones.

Hi-End Preamplifier Output

In addition to its headphone outputs, the P2 MK2 functions as a reference-grade analog preamplifier. Balanced XLR and single-ended RCA preamp outputs allow direct connection to a power amplifier or active speakers, making the P2 MK2 the control center of a world-class desktop or full-size audio system.

USB Firmware Upgrade Support

Future-proof your investment. The P2 MK2 supports firmware upgrades via USB, allowing SMSL to deliver performance improvements, feature additions, and compatibility updates over time. This is a platform designed to evolve with you.
