Oyaide MTB-4 II Power Distributor

The Oyaide MTB-4 II is a premium 4-outlet AC power distributor built for serious hi-fi systems that demand stable power delivery, mechanical integrity, and careful material selection. Designed and made in Japan, it combines a 2mm brass chassis, high-purity silver internal wiring, and Oyaide’s purpose-built outlet architecture for a cleaner, more deliberate approach to system power distribution.

For customers building a refined analog or digital front end, the MTB-4 II is an excellent fit for systems with streamers, DACs, preamps, headphone amplifiers, integrated amplifiers, and source components where consistency, grounding, and contact quality matter.

Why the Oyaide MTB-4 II Stands Out

• Premium 4-outlet power distributor for high-end audio systems
• 2.0mm 4N silver internal wiring
• 2mm brass enclosure
• Oyaide SWO-DX-ULTIMO or optional R-1 outlet platform
• Power Inlet PP AC inlet
• Parallel wiring for separate sockets
• Ground wiring: 3398-14
• Brass cone feet and mixed-material vibration control
• Electromagnetic wave absorber treatment
• Made in Japan

Design Philosophy

The MTB-4 II is not a generic power strip dressed up for audio use. Oyaide treats power distribution as a core part of system performance, paying attention to conductor purity, outlet quality, chassis material, mechanical damping, and grounding behavior. The result is a purpose-built distributor designed for serious listening environments rather than office or consumer-grade convenience use.

High-Purity Internal Wiring

The MTB-4 II uses 2.0mm 4N silver internal wiring. In a high-resolution system, internal wiring quality matters because current delivery, contact integrity, and overall signal environment begin at the power foundation.

Brass Chassis and Mechanical Control

The enclosure uses a 2mm brass body. Oyaide pairs this with vibration-control measures including brass cone feet and mixed-material damping concepts to address both shielding and resonance behavior.

Audio-Grade Outlet Architecture

The MTB-4 II is built around Oyaide’s dedicated SWO-DX-ULTIMO or optional R-1 outlet platform and Power Inlet PP inlet design, helping maintain stable physical connection and consistent contact quality across connected components.

What Does a Power Distributor Do in an Audio System?

A power distributor gives your system a central, better-built point for AC connection. In audio systems, that matters because the quality of outlets, internal wiring, grounding structure, and chassis construction can affect noise, stability, and long-term reliability. A true audio-grade power distributor is designed to support system performance, not just add more outlets.

Does a Power Strip Improve Sound Quality?

A generic power strip is usually built for convenience. A high-end power distributor is built to reduce compromise. While it is not a tone control and does not “add” detail artificially, a better-designed power distributor can help preserve system performance by improving contact quality, lowering mechanical and electrical interference, and providing a more stable power foundation for sensitive audio components.

Why Use a High-End Power Distributor?

• Better outlet and connector quality than commodity strips
• Improved mechanical stability and resonance control
• More appropriate materials for hi-fi use
• Higher confidence in grounding and connection consistency
• More suitable for resolving systems with quality source and amplification components

Best System Matches

• Network streamers and music servers
• DACs and headphone amplifiers
• Preamplifiers and phono stages
• Integrated amplifiers
• Reference desktop and 2-channel hi-fi systems

FAQ

What does a power distributor do in audio systems?

A power distributor provides a central AC connection point for audio components. In higher-end systems, build quality, outlet quality, internal wiring, and grounding behavior can all matter more than they do with a standard consumer power strip.

Does a power strip improve sound quality?

A commodity power strip is mainly about convenience. An audio-grade power distributor is designed to reduce compromise in current delivery, connection stability, mechanical behavior, and electrical noise management. In a revealing system, that can help preserve overall performance.

Why use a high-end power distributor?

Because a resolving audio system benefits from better materials, better contact quality, and more stable power distribution. It is one of the most sensible foundational upgrades when the rest of the system is already capable of exposing weaknesses upstream.
