SJS Arcadia Model 7 Line Pre-amplifier

Following on from the successful launch of the Model 3 riaa, and the Model 5 power amp, SJS Electroacoustics are pleased to present the new Model 7 line stage pre-amplifier. The Model 7 has been designed as the 20th Anniversary re-imagination of the original Arcadia Model 1 line stage pre-amplifier, which was first delivered to customers in early 1997.


The Arcadia Model 7 line stage is based upon the same 6111wa NOS military valve and has been specifically engineered for sonic performance rather than technical specification, and fulfils all SJS Electroacoustics primary design criteria:
  • Single Ended circuit topology
  • Pure Class A operation
  • Zero negative feedback
  • Valve rectification and choke-input HT power supply
  • Custom made HT T-network power supply capacitors with silver leads
  • Point-to-point circuit wiring without PCBs
  • Hand built
  • PTFE board for component mounting
  • High quality components throughout
  • Custom made aluminium chassis


Design Options
The Model 7 line pre-amplifier is hand built to order in England, and therefore we are bale to offer customisation to meet your sonic preferences. Bespoke customisation of the internal components is possible to meet our clients' specific requirements, whether it is replacement of the Audyn capacitors with Dueland RS or CAST or possibly even using Tantalum film resistors, for example, these can be discussed at the point of ordering.
