US maker of high end amplifiers.

Signal Path International

USA based company that sells consumer audio products under the Peachtree Audio brand, these are primarily amplifiers and pre-amplifiers with integrated USB sockets and iPod docks, in addition to similarly outfitted DAC's and a couple of small loudspeaker designs. The company also used to manufacture hi-fi furniture under the Sona Design label and loudspeakers under the ERA name but has now folded that line into the Peachtree brand, presumably since the ERA brand is owned by other companies in Europe and Asia.

Distributed in Singapore by Advance Acoustics, in Switzerland by Portier Hi-Fi and in Taiwan by Super Plus International.


German manufacturer of high end loudspeakers and audio utility products. The SilberSand speakers are all active speakers where each driver has its own amplifier which is fed from an DSP based active filter network that adjusts the workings of the filters and amplifiers in real time by using look ahead algorithms and data from sensors inside the speakers. But the most intriguing product from the company are the "FM" modules, a truly modular loudspeaker system where you buy a base that contains the power supply, DSP & crossover, then you can add bass, midrange and tweeter modules, all in their own baffle and with a built in amplifier, allowing you to build up a system ranging from a small bookshelf to a large tower with a symmetrical speaker arrangement.

Company was originally founded in October 1985 by Friedrich Müller and Ursula Luckscheiter, and was then called "Silbersand Müller & Luckscheiter GmbH", but Hr. Müller had left Backes & Müller earlier that year after losing control of the company.
