Audio Music R-S Passive Pre amplifier

To some audiophiles, a Passive Preamp sounds odd and mysterious; but to some senior hifi guru, Passive Preamp may represent a pure and simple pursue of the extreme high fidelity. Anyway, what is a Passive Preamp? Simply to say, passive here means no active circuitry, i.e. no connection to AC wall power, in short, no power supply. But now days, the request of convenience, for example, the need of remote control function has narrowed the concept of passive. Maybe no power on audio circuit is more precise definition to the word "Passive". Passive Magnetic is the high level type of Passive Preamp. Magnetic refers to the use of multi-tapped attenuation transformers instead of resistive volume control devices. However, design and manufacturing of this type of transformer is quite a complicated work. Also being a high end audio transformer supplier, AMR-S has dedicated to the research and manufacturing of audiophile grade transformer for years. Housed inside refined high quality aluminum alloy chassis, AMR-S presents one of the best Passive Magnetic preamplifiers in the market
This is fully balanced in and out and out performs other similar types of passive and is built to a very high standard purchased from Ian Borthwick at LW Audio last year at £1998 selling at £1199
