SC Cut ultra low phase noise OCXO
The X-3 incorporates an SC Cut ultra low phase noise OXCO (thermostatic bath-type crystal oscillator) selected for its unprecedented sound quality.



Naked foil resistors
As they greatly impact clock sound quality, the output resistors employ naked foil resistors adapted from artificial satellite grade ultra-high precision resistors, with exceptional thermal properties and low thermal noise, and then further customized. Soulnote believes that at this stage, this is where extraordinary resistors are most effective.



SMA output terminal
The output clock signal originates from an SMA terminal with specs above 20 GHz. Only one output is provided for the ultimate in sound quality. The X-3 is supplied with an SMA–SMA 50ohm dedicated clock cable, but Soulnote highly recommends using the optional RCC-1 clock cable. Relive music that unleashes the ambiences of the soul.



non-NFB power supply
A high-capacity 200 VA toroidal transformer normally used in 100 W power amps provides an abundant power supply to drive the crystal oscillator. The rectifier diode relies on newly adopted ultra high-speed SiC diodes. The rectifier group is composed of numerous low-magnification, small-capacity electrolytic condensers connected in parallel, while the regulator incorporates Soulnote's unique non-NFB discrete power supply.

Quiet power supply domain 
All unnecessary circuits like power supply LEDs, relays, etc. have been stripped from the crystal oscillator to provide a super-quiet power supply domain.

Housing prioritizing sound quality
The X-3 housing adopts unique new design. The housing consolidates features like air dump elimination through a dual non-rigid top plate, non-rigid AC inlets, non-rigid output terminals, three spike supports directly under the transformers, titanium washers, carbon washers, and more. Soulnote's core expertise has developed sound of the highest quality.

Notes on this product
Never connect XLR-RCA converter cables, adapters, short pins, or similar connectors to analog output terminals. They could damage the equipment. 
Temperature settings:

The circuit current in Soulnote products relies on solutions with the highest emphasis on sound quality and safety. Functionality and sound quality generally improve when the transistors operate at higher temperature. 

Anti-vibration housing: 
Soulnote products place the highest emphasis on sound quality, so the top cover, chassis, and other components do not employ vibration isolation. 

Regarding use of electronic equipment cleaners and contact rejuvenation products on Soulnote products:
Commercially available electronic equipment cleaners and contact rejuvenation products could damage the resin components of Soulnote AC inlets. Do not use these types of chemical products on Soulnote equipment.
