Modwright Instruments

What Modwright Instruments does

ModWright Instruments is a privately held, founder-owned manufacturer of high-end two-channel audio equipment based in Amboy, Washington, founded in 2000 by Daniel Wright. The company designs and hand-assembles tube and solid-state amplifiers, balanced tube preamplifiers, tube phono stages, a tube DAC, and a unity-gain tube buffer, plus modification services for third-party digital products. Core technology centers on hybrid tube/solid-state architectures, notably the Solid State Music Stage (SSMS) with zero global negative feedback and single-stage topology, transformer-coupled input/output paths, oversized linear power supplies, and high-bias Class A/B amplification. The PH 9.0 series (PH 9.0, 9.0X, 9.0XT) is the company's best-selling line, with a structured factory-direct upgrade path that enables incremental revenue from the existing customer base.

ModWright sells exclusively into the high-end audiophile segment, with products priced from approximately $3,500 to over $10,000 per unit, distributed through 11 U.S. dealers and 12+ international distributors across countries including Australia, France, Germany, Hong Kong, Singapore, Canada, and Mexico, with direct factory sales at identical pricing. The company actively exhibits at AXPONA, Pacific Audio Fest, Capital Audio Fest, Florida Audio Expo, and Munich High End, and runs a long-form technical blog (ModBlog) and a YouTube channel launched in late 2024. Customer acquisition is consultative and quote-based, with no public pricing, and the dealer network is structured to provide system-matching guidance. ModWright has received consistent third-party validation across more than a decade, including recognition from The Absolute Sound, Positive Feedback Online, HiFi Choice, The Ear, and Steve Huff / HiFi Huff, and the company described 2025 as one of its best sales years. The KWA 300 Reference Stereo Power Amplifier, launching in 2026, represents the company's most recent flagship product introduction, extending the high end of the amplifier line.
