EverSolo AMP-F2 Stereo Power Amplifier at Vinyl Sound Buffalo, NY USA

The AMP-F2 is a Class D stereo power amplifier developed by EverSolo (Shenzhen, China) in collaboration with Starke Sound (California, USA), available at Vinyl Sound in Buffalo, NY, USA. Built around Starke Sound's NS600 amplifier module with PurePath Ultra HD technology, the AMP-F2 delivers 145 W per channel at 8 ohms and 250 W per channel at 4 ohms, rising to 450 W at 2 ohms in bridged mono mode. It achieves THD of 0.003% at 10 W / 1 kHz and SNR exceeding 110 dB, powered by a 600 W SAPS audio-specific switching supply with a high internal sampling rate of up to 600 kHz. Physically dimensioned to pair directly with the EverSolo DMP-A6 series, the AMP-F2 is available to audiophiles across Western New York at Vinyl Sound, an authorized EverSolo dealer in Buffalo.

Starke Sound NS600 Module, PurePath Ultra HD, and SAPS Power Supply

The AMP-F2's amplification core is Starke Sound's NS600 module, a high-performance Class D design used in Starke Sound's own professional and home theater amplifiers. The NS600 uses PurePath Ultra HD technology with an advanced integrated feedback design and high-speed gate driver error correction function, achieving ultra-low distortion across the full audio frequency range at a high internal switching rate of up to 600 kHz. This elevated switching frequency positions the switching noise well above the audible band, reducing the burden on the output filter and contributing to the amplifier's measured 0.003% THD at 10 W / 1 kHz and SNR exceeding 110 dB. The 600 W SAPS (Starke Audio Power Supply) is a purpose-designed audio-specific switching supply with high efficiency, low ripple, and low EMI — significantly better controlled than generic switching designs — that enhances dynamic performance and maintains a low noise floor under sustained high-power output. Custom beryllium copper speaker binding posts manufactured by Starke Sound are provided, offering excellent conductivity and long-term oxidation resistance.

Bridge Mode, Trigger System, and System Integration

The AMP-F2 is bridgeable via a rear-panel switch, converting the stereo amplifier into a mono configuration delivering 280 W at 4 ohms and 450 W at 2 ohms (THD below 1%). The minimum load impedance in bridge mode is 2 ohms, making the AMP-F2 capable of driving very demanding low-impedance speakers without instability. A 5–12 V trigger input and output in 3.5 mm jack format enables automatic power sequencing with EverSolo streamers and other trigger-equipped devices — a USB-to-trigger cable is included for direct sync with the DMP-A6 series. The AMP-F2's compact chassis dimensions of 270 x 228 x 80 mm are deliberately matched to the DMP-A6 footprint, allowing it to sit alongside or on top of the DMP-A6 or DMP-A6 Master Edition as a visually coordinated pairing. Standby power is ≤0.5 W and idle consumption ≤14 W, meeting EU ErP energy efficiency standards.

Technical Specifications

Frequently Asked Questions

What is the EverSolo AMP-F2?

The EverSolo AMP-F2 is a Class D stereo power amplifier co-developed by EverSolo and Starke Sound of California, built around Starke Sound's NS600 module with PurePath Ultra HD technology. It delivers 145 W per channel at 8 ohms and 250 W per channel at 4 ohms in stereo, rising to 450 W at 2 ohms in bridged mono mode, with THD of 0.003% at 10 W / 1 kHz and SNR exceeding 110 dB. It is dimensioned to pair physically with the EverSolo DMP-A6 series and includes a trigger system for automated power sequencing.

How does the EverSolo AMP-F2 compare to the EverSolo AMP-F10?

The AMP-F10 is EverSolo's Class AB flagship power amplifier, delivering 200 W per channel at 8 ohms and 320 W per channel at 4 ohms via five pairs of MOSFET output transistors and a 1,000 W dual-channel linear power supply. The AMP-F2 is a Class D design based on Starke Sound's NS600 module using a 600 W switching supply, offering 145 W at 8 ohms and 250 W at 4 ohms in a far more compact chassis dimensioned to pair with the DMP-A6 series. The AMP-F10 is intended as the partner for the DMP-A10 in a reference-level system; the AMP-F2 is designed for compact, efficient two-channel systems built around the DMP-A6 or DMP-A6 Master Edition series.

What streaming DACs pair with the EverSolo AMP-F2?

The AMP-F2 was designed as a direct physical and sonic match for the EverSolo DMP-A6, DMP-A6 Gen 2, and DMP-A6 Master Edition Gen 2, all of which share the same 270 mm chassis width and provide a 12V trigger output for automated power sequencing with the AMP-F2. The included USB-to-trigger cable enables plug-and-play power sync with the DMP-A6 series. The AMP-F2 accepts both balanced XLR and single-ended RCA inputs at 10.5–21.7 kohms, making it compatible with any streaming DAC or preamplifier with a variable output.

Can the EverSolo AMP-F2 be used as a monoblock amplifier?

The AMP-F2 is bridgeable to mono via a rear-panel switch, converting it to a single-channel output of 280 W at 4 ohms or 450 W at 2 ohms, with THD below 1%. Two AMP-F2 units are required for a stereo monoblock configuration, one per channel. Bridge mode is best suited to high-current, low-impedance speakers or large room systems where the standard stereo output of 250 W at 4 ohms would be insufficient for the required listening levels.

What speakers are suitable for the EverSolo AMP-F2?

The AMP-F2's minimum load impedance of 0.8 ohms in stereo and SNR exceeding 110 dB make it capable of driving a very wide range of loudspeakers, including demanding electrostatic and planar magnetic designs. In practice, its output of 145 W at 8 ohms and 250 W at 4 ohms is generous for most bookshelf, standmount, and compact floorstanding speakers available at Vinyl Sound in Buffalo, including PSB, Wharfedale, DALI, and Klipsch models across the Reference and Heritage lines.
