Arcadia Line Level Preamplifiers

Between 1996 and 1998 the original run of SJS Arcadia Model 1 and Model 2 line stage pre-amplifiers were delivered. Over the past few years a number have been back for service, repairs or upgrades, so I thought it may be useful to present some of the original information here.

SJS Arcadia Model 1 and Model 2 Line Level Preamplifiers

6 line inputs, 2 tape loops, 10dB of gain, zero feedback
finest quality components, musical results

The Arcadia bespoke line level pre-amplifiers offer the very finest musical results for all high quality systems. When paired with one of the matching Arcadia phono stages vinyl reproduction will obtain a level far beyond that of an integrated pre-amplifier.

By carefully balancing all aspects of the design, the Arcadia line level pre-amplifiers offer a level of gain and drive suitable most power amplifiers; whether valve or solid state. Utilising a special valve rectified, choke filtered, power supply, and avoiding sonically degrading feedback; the Arcadia pre-amplifiers offer a natural tonal balance, which is fluid, of full tone and grain free. The strong dynamics are balanced by a deft touch to produce an enlightening musical experience.

The Model 2 builds upon the strengths of the Model 1 and improves all aspects of performance whilst retaining the dynamic capabilities and control of the Model 1. Built with a completely copper chassis, and the very highest quality components available, the Model 2 offers a level of coherent transparency unmatched at the price.

"There's none of the wispy airiness and soft, slow bass that one associates with the breed - just consistently fine tone, edge-of-your-seat dynamics and effortlessness." Jason Kennedy on the Model 1 in HiFi Choice Sept '97.
