Starkrimson 25 Amplifier Module

The Starkrimson 25 Amplifier Module brings Orchard Audio’s next-generation GaNM technology to DIY builders, system designers, and OEMs who want exceptional sonic performance in a compact, efficient, and easy-to-integrate form factor. Based on the same engineering principles as the award-winning Starkrimson series, the Starkrimson 25 delivers remarkable clarity, speed, and transparency — all while maintaining ultra-low noise and distortion.

Switching at an exceptionally high 1.1 MHz, this GaN-based Class-D module offers superior transient response, outstanding detail retrieval, and a natural, highly resolving presentation. Its fully balanced architecture and proprietary dual feedback design ensure clean, stable operation even in demanding applications.

Whether you’re building a compact desktop amplifier, an active speaker system, or a custom multi‑channel setup, the Starkrimson 25 Module provides reference‑grade performance in a footprint that fits almost anywhere.

What Makes the Starkrimson 25 Amplifier Module Special?

The Starkrimson 25 Module is engineered for builders who want the sonic advantages of GaNM technology without the complexity of designing a full amplifier from scratch. Its high switching frequency, balanced topology, and precision feedback architecture give it a level of transparency and musicality rarely found in modules of this size.

Here’s a snapshot of the key highlights:

• 1.1 MHz switching frequency for exceptional transient response and detail
• GaNM transistor technology for speed, efficiency, and low distortion
• Fully balanced signal path for ultra‑clean amplification
• Proprietary dual‑feedback architecture for stability and accuracy
• Compact, easy‑to‑integrate module ideal for DIY and OEM applications
• Low noise floor for high‑resolution audio systems
• 150W into 8Ω / 200W into 4Ω
• Fully stable down to 1 ohm

This module is designed to deliver the same “flat wire with gain” neutrality that Orchard Audio amplifiers are known for — but in a flexible, builder‑friendly format.

Designed for Real-World Music Loving DIYers, Engineers, and System Builders

While some high-end gear prioritizes looks and/or specs over musicality, Orchard Audio’s approach balances both. Because it’s fully balanced from input to output and built with state-of-the-art components, the Starkrimson 25 Module doesn’t just produce power — it preserves the nuance and texture of your recordings. Reviews and listening reports highlight its ability to bring out micro-detail, soundstage, and layering in music that can get lost in lesser amps.

Whether you’re listening to jazz, classical, rock, or electronica, this amplifier stays composed and musical through complex passages.

The Starkrimson 25 Module is perfect for anyone who wants high‑end GaNM performance in a customizable package. It’s engineered for:

• DIY amplifier builds
• Active speaker projects
• Multi‑channel home theater systems
• Compact or portable high‑end audio designs
• OEM integration into commercial products

Its balanced input stage and robust output section make it easy to pair with modern DACs,preamps, and DSP‑based systems.

The Reviewers Are Raving About the Orchard Audio Starkrimson 25 Amplifiers

The audiophile press is raving about the Orchard Audio Valencia. Here’s what they have to say…

Gerardo A – vAudio Architect (January 2026)

"Service, Support, and an excellent value product, as good as the big players, even better, mind you."

Doug Moore – The Sound Advocate (October 2025)

"The Starkrimson 25 Monos were an awe-inspiring set of amplifiers that demonstrated to me how far we have come in the last few years of amplifier design. They were fantastically dynamic when needed, offering a wealth of neutrality that let the instruments speak for themselves, and allowed my reference OB speakers to work their magic to the best of their ability. At $2,500 per pair, I can’t think of a better set of amplifiers at that price. They perform well enough that you have to ask yourself if spending more will really yield you any better enjoyment of the music you love, and that is the point, isn’t it! To enjoy the music we love."

Andrew Dewhirst – Future Audiophile (September 2025)

"The Orchard Audio Starkrimson 25 Mono Premium amplifiers truly are game-changers in the audiophile industry, to the point that I think many people should strongly consider looking at GaN FET amplifiers like these moving forward as the first thing they contemplate, instead of, say, more traditional Class-A/B designs. The combination of power, low heat, and low weight to go along with sound that comes close to what you might pay for from an amp that is four times more expensive, is one that I can say I haven’t run into in quite some time. I will have to really consider if I wish to send the Starkrimson 25 Mono Premium amplifiers back to Orchard Audio, as they really are that good."
