Given the evolving nature of wireless technologies such as WiFi and Bluetooth that are used to drive amplifiers, we decided not to "buy in" to any technological standard but to develop a great sounding minimalist amplifier that allows the user to connect through a wide variety of wireless sources, such as the Amazon Echo Dot and the Google Chrome Audio, or to connect to the amplifier directly via its RCA or 3.5 mm inputs.
The A100 is a modified 100 watt per channel stereo amplifier featuring the TPA3116 chipset with dual-core technology for high efficiency, low heat, and accuracy.
We modified the amplifier to improve its bass performance, the definition of its soundstage, its dynamic punch, and to improve its high frequency detail and its musicality.
As a result, the A100 is a very musical amp with extraordinary imaging and soundstaging and a very tubelike sound. And yet, for a digital amplifier, it has exceptional dampening factor that allows it to drive even some difficult to drive loudspeakers. Moreover, we have teamed the A100 with a switch mode 24 VDC, 5 AMP AC to DC power supply to extricate the maximum wattage from it.
The A100 features gorgeous, health friendly and Eco-friendly, non-toxic, retro, Baltic white birch plywood or satin black MDF cabinets.
We have tested our modified A100 amplifier with a wide range of speakers against some highly regarded amplifiers, many times its price. Our conclusion is that the A100 is an amazing amplifier, especially if you feed the A100 a quality signal, such as through a DAC.

"Just wanted to let you know that the MasterSource speaker cables are sounding great. Soundstage is deeper than the other cables I was using - which were very high-end priced cables. Thank you for a great product."
