Description
The Oyaide OSP-SC is a high-quality small brass spike featuring an M4 threaded post, designed to deliver precise vibration control, mechanical grounding, and resonance tuning for high-fidelity audio equipment. It’s ideal for users looking to replace stock feet or upgrade vibration isolation in compact gear that supports M4-thread mounting.
Basic
The OCB-1 series has undergone a minor change in spring 2012. In conjunction with this change, the OSP-SC, a machined brass spike, an optional product for the OCB-1 series, will be released in the summer of 2012.
The OSP-SC is a conventional “OSP” spike with M4 threads, which can be easily installed by hand into the M4 threaded holes on the bottom corners of the OCB-1 to further enhance the performance of the OCB-1.
Features
The OSP-SC can be attached to the latest minor change model of the OCB-1 series and is designed to be screwed into the four corners of the bottom surface of the OCB-1. The screw size is M4. Therefore, the OSP-SC can be attached to any model other than the OCB-1 as long as it has M4 size screw holes.
With OSP-SC, OCB-1 achieves point contact and dampens vibrations from the floor surface. By attenuating vibration, which is a major cause of sound quality degradation, OSP-SC further enhances the performance of OCB-1.
🔧 Key Features
✅ Brass Spike with M4 Thread
-
Easily screws into gear that accepts M4-threaded feet or standoffs
-
Brass provides excellent mass damping, rigidity, and vibration control
-
Threads are precision-cut for stable and secure fitment
✅ Compact Form Factor
-
Designed for tight installations where larger feet/spikes won’t fit
-
Low-profile but effective — doesn’t overly raise the component’s height
✅ Tuning Benefits
-
Mechanically grounds vibrations from transformers, circuit boards, and enclosures
-
Drains excess energy into a rigid rack or surface, preventing re-radiation into sensitive circuits
🔊 Sonic Improvements
-
Tighter bass response
-
Improved micro-detail and imaging
-
Cleaner, less smeared highs — especially in analog and digital front-end gear
🎯 Best For:
-
Oyaide components like the OCB-1 ST II, power distributors, and small chassis gear
-
Any device that accepts M4-threaded footers
-
Audiophiles seeking subtle but real gains in system clarity and stability
🛠️ Pro Tips:
-
Install 3 spikes for natural leveling, or 4 for full corner support
-
Combine with brass or carbon base discs if placing on delicate or reflective surfaces
-
Always test torque during installation to avoid stripping small-thread inserts
