About The AMC XIA50 Stereo Amplifier
The AMC XIA50 is the next step up from the excellent entry level XIA30 amplifier. It's a high current design which punches well above its weight and is a bargain for the asking price.
Phono Stage: The XIA50 uses a unique phono stage design that employs two audiophile grade op-amps per channel that provide very low THD, TIM and noise, together with switchable Moving Magnet or Moving Coil cartridge options.
Tone Controls: The XIA50 incorporates a specially designed passive tone control circuit to give natural sound quality. The tone control stage can be completely by-passed with the Direct switch to give natural sound quality.
High Quality Components: The XIA50 uses some very nice audiophile grade components throughout, providing exceptional accuracy to phono and tone control responses and a nice full sound even at lower volumes.
High Current: The ability to really drive dynamic passive speakers is down to good current delivery and the XIA50 has this in spades. The power amplifier section in the XIA50 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 demands. Furthermore the XIA50 employs a specially designed output stage using perfect virtual image topology to make it possible to connect directly to your loudspeakers without the need for relay contacts to offer the best sound quality possible.
Toroidal Transformer: Of course no amplifier is complete without a competent power supply section and a robust toroidal transformer able to provide the continuous power needs of the amplifier circuit. The universal power transformer in the XIA50 has passed all international safety standards and exhibits exceptionally low RF noise to help give the XIA50 the ultimate in crystal clear sound.
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.
Our Take
The AMC XIA50 is an analogue integrated amplifier. It is constructed and voiced in the tradition of the famous NAD 3020i amplifier from 1991. In fact the XIA50 is manufactured in the same factory and to the same high standards as that iconic amplifier. It even has the same green power button used on the 3020i all those years ago. The XIA50 has quite a comprehensive array of inputs including three line level inputs, and, wonder of wonders in this day and age, a tape loop, for those who can make use of such a convenience. It also sports a phono input which can be switched between Moving Magnet & Moving Coil as well as Pre Out / Main In which anyone familiar with the aforementioned NAD will be very familiar with. It also has a 4Ω/8Ω switch so you can more accurately match the amplifier to the speakers. There is a removable IEC mains power cable, which can be easily upgraded and finally some rather nice quality speaker binding posts which can accept banana plugs, spades or bare wire.
