Chassis Design and Functions

The new B version keeps the same heavy gauge steel chassis with 3/16" brushed and anodized aluminum front and rear panels, secured by stainless steel hardware, with highest quality gold plated speaker binding posts. Available with Neutrik single-ended RCA or balanced XLR input

The mute function puts the amplifier in a standby mode, allowing critical circuitry to be kept powered and eliminate any warmup period.

Power Supply

A newly designed power transformer uses multiple discrete windings for each individual power supply circuit and a new circuit board handles filtering and regulation. We also added our XDC-2 circuit to insure low operating noise.

Being over 90% efficient means the amplifier runs cool and extends the life of all internal components, and built-in safety features protect it from shorted speaker cables and components.

Audio Circuit

High current capability and low output impedance allow the D•100B to drive difficult loads with excellent control, producing 100 watts into 8 ohms and 200 watts into 4 ohms. The input stage has also been updated to MKII status, insuring that all our amplifiers have the same uncolored sound.

For me, the D-100s had a lot of dynamic capability and very powerful, controlled bass… Living with the Channel Islands D-100s for a while was a very good experience. These amplifiers are solidly built and offer better sound than their modest price would suggest. The D-100s are also very versatile, they were able to drive any speaker I threw at them with ease. Thanks to the small footprint, low power consumption and low heat output, this is as easy as high-end sound gets.”

I felt as if I were listening to the music rather than the amps, which is what we are all pursuing, isn’t it? These amps helped me through the complex transitions without impeding my travels. Channel separation, a main advantage of employing monoblocks, was exemplary… These amps outperform their price range by a significant margin.”
