Silbatone JI300 Mk.III


We are proud to introduce our latest third-generation integrated amplifier, the JI300 Mk.III. This design presents a substantial upgrade to our popular JI300 series of 300B stereo integrated amplifiers, highly-regarded since the year 2000 for providing world class performance in a meticulously-engineered, compact, and elegant package.

The Mk.III can replace a large rack of equipment with a single box and provide better sound than most large-scale multi-chassis systems as a benefit. As always, Silbatone tailors ergonomics and features for the way today’s audiophiles build world-class systems, providing the essential control capabilities you need with superlative performance for maximum enjoyment in the most uncompromising music listening systems.

 

Compared with many top grade amplifiers, Silbatone's MK.III stereo integrated triode amplifier is a mid-priced unit, but we are confident that value and musical performance is approached by few units regardless of cost.

 

 

As with other Silbatone designs, parts quality is far beyond other commercially produced amplifiers. All components for Silbatone electronics are selected according to listening tests and technical performance without regard for cost. We use custom-manufactured low noise wirewound signal resistors and expensive silver litz internal wiring for ultimate musicality and detail. Our signal capacitors are custom manufactured silver units that are unavailable elsewhere. The JI series output transformer is the latest enhancement of our exclusive "Semi-Silver" foil design on a high-mu nickel core.

An important departure from the previous JI300 line is our adoption of a Teflon circuit board, which yields a considerable improvement in low level detail and enhances the smooth and lively sonic character of the design. The superior electrical characteristics of Teflon and the self-damping mechanical qualities of this material deserve more exposure, although at 10x the price of highest-grade epoxy boards they are cost-prohibitive for most manufacturers. The sonic difference is substantial and worth the high cost.

We understand that the power supply is the heart of the amplifier and this aspect was substantially upgraded in the Mk.III version, including an enhanced passive cooling system initially developed for the Reference 300 Amplifier.

With the JI300 Mk.III, we have made great progress in closing the performance gap between our standard line and our flagship Reference 300 Amplifier. We are even more confident that the JI series provides the highest level of performance and value on the market today.

As with other Silbatone amplifiers, the Mk.III is CNC milled from aluminum billet, designed to address both visual aesthetics and functional considerations, such as shielding, cooling, and vibration control. The benefits of our solid, non-resonant chassis are immediately audible compared with the cheap sheet metal structures employed by most manufacturers. No screws or fasteners are visible on the outside of any Silbatone chassis. Fit and finish are impeccable, the result of careful hand detailing and flawless precision machining.

Voltage amplifier (Type 5965) and driver tubes (Type 5687) are industrial-grade twin triode devices, chosen for high performance.

Other types such as E180CC/7062 and 12AY7/6072 can substitute for 5965, and 7119 or the rare Bendix 6900 can alternate for the 5687 depending on preferences and system matching considerations.

Our circuit is fully compatible with original specification WE 300B power tubes and most modern improved versions.

The remarkable success of the JI300 amplifier in the Korean high-end market has been very gratifying, with hundreds of units sold. Our amps are displayed next to the most expensive and highly rated gear in the world. While far less expensive than many imported US and European products, our build quality is unsurpassed and musical performance is superior to the competition. Very few Silbatone units appear on the used market, a marker of long-term customer satisfaction.

Our 300B amplifiers are often demonstrated with and sold with modern loudspeakers that are not usually considered candidates for low-powered tube amplification, including Wilson Watt/Puppy and Kharma models. High-tech power supply topologies and low-loss, high bandwidth output transformers contribute to the otherworldly drive capability of our amplifiers, an aspect of Silbatone performance that must be experienced to be believed!

With the JI300 Mk.III amplifier, we feel that the Silbatone advantage has been greatly enhanced. Previous versions were regarded as the finest integrated amplifiers ever manufactured and our newest model takes that tradition of performance to a new level.
