AMC 25100 MKII 5 Channel Power Amplifier
The AMC 25100 MKII is a 5 channel power amplifier primarily used to expand the number of channels and increase the performance of a home theatre system with an existing home theatre receiver or preamp/processor.
Amplifiers reproducing dynamic signals must do so without interfering with each other. In high quality amplifiers, circuit design is critical in order to achieve maximum performance and exceptional sound. Each output of the 25100 MKII is powered by an independent Power Module™. Each module is identically constructed, allowing completely independent management of signals from input to output.
This concept enables each channel to monitor heat, current, signal, and power separately, thus greatly reducing crosstalk and increasing dynamic range and efficiency. The Power Module utilizes a unipolar output ensuring proper phase and matching between channels. The Power Module™, design utilizes high current output devices in conjunction with a dual voltage power supply and an oversized toroidal transformer that in combination, delivers up to 20% more power than normal amplifiers of the same size. The 25100 MKII is capable of delivering massive amounts of power into the type of low impedance loads exhibited by virtually all modern loudspeakers.
Audiophile Grade Components: Although the case is deliberately Spartan, no expense has been spared on all the bits you can't see, but which greatly effect performance. Audiophile grade components are used throughout, to make sure that the 25100 MKII provides superb sound quality.
Toroidal Transformer: Power supplies are the heart of any power amplifier and the transformer can make or break the quality of the power supply. Fortunately the 25100 MKII employs a huge toroidal transformer in the power supply which helps the amplifier deliver impressive amounts of power into low impedance loads which means it will drive virtually any loudspeakers.
Input/Output Flexibility: Each input has a level control as well as an accompanying line output RCA jack which can pass the signal on to another amplifier's input for use in a Bi-Amp or Multi-Amp installation.
Gold Connectors: Helping to transfer all signals in and out of the amplifier in the most reliable way, all RCA connectors and the substantial binding post speaker terminals are gold plated for the most reliable audio connection. The heavy duty gold plated binding posts are designed to handle the extremely high peak currents that this amplifier is capable of.
High Current: The ability to really drive dynamic passive speakers is down to good current delivery and the 25100 MKII has everything you need. The amplifier section in the 25100 MKII includes 50 Amp high peak output devices and an optimised power supply design to keep speakers in check and provide the sort of dynamic drive modern music and home theatre demands.
About AMC
Since 1970, AMC has forged a reputation for being a powerful and reliable electronics manufacturer in the Hi-Fi and Smart Home business. AMC is responsible for some of the world's most famous brands and high-end esoteric electronics. Their main focus is to build reliable and powerful amplifiers with a life expectancy of at least 25 years.
Peter Bath and Malcolm Blockley, formerly at NAD, Acoustic Research, Proton and others, have harnessed the cost efficiencies that are available from AMC's "common-platform" product design and production efficiency to bring to market a product range that pretty much ticks all the boxes on an Audiophile's wish list … at very attractive prices.
Our Take On The AMC 25100 MKII Power Amplifier
The AMC 25100 MKII is a 5 channel power amplifier primarily used to expand the number of channels and increase the performance of a home theatre system with an existing home theatre receiver or preamp/processor. It has a massive power supply which enables it to provide high current and power almost any speakers to high levels, no matter the load. It uses five independent AMC Power Modules™ which deliver up to 20% more power than normal amplifiers of the same size. This concept also enables each channel to monitor heat, current, signal, and power separately, thus greatly reducing crosstalk and increasing dynamic range and efficiency. The 25100 MKII is capable of delivering massive amounts of power into the type of low impedance loads exhibited by virtually all modern loudspeakers. Given the very reasonable price, we think this is quite an achievement.
