SJS Arcadia Model 7 Line Pre-amplifier

[sjs]

Following on from the successful launch of the Model 3 MM RIAA phono amplifier, and the Model 5 Stereo SE 300B Power Amplifier, 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 preamplifier, 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

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.





Each amplifier comes with 2 years parts a labour warranty, except for the valves which have a 6 month warranty.

SJS Arcadia amplifiers are available from Definitive Audio in Nottingham

Maybe I'm missing something but couldn't find any details about SJS on the Definitive Audio website ...

There is a small piece in the news section as they have just taken the amps on (again)...... more to follow

Definitive were one of my dealers back in the late 90s so it's good to be working with them again.

At the moment, the most info is on my blog:

Or ping me a message if you want to know anything specific.

sounds good , 20 % off what though ?

would this performance fall below the 1.5 if it is based on the 1 ?

20% off the inc vat list price of any of the new amps: Model 3 riaa, Model 5 se 300B, Model 6 riaa, Model 7 line, Model 8 se 300B amp, Aoide headphone amp

The Model 1 was the original steel case entry level unit form the late 90s, the Model 2 was available at the same time as a higher spec copper case version of the same design. The Model 1.5 is a name coined to refer to the original Model 1 units which have been back for a significant upgrade to the internal parts to move them towards the performance of the Model 2. A number of these Model 1.5 units have come about over the past few years.

The Model 1, Model 1.5, Model 2 and Model 7 are all the same basic circuit design, using the 6111wa valve. The difference is in the execution, parts, layout and chassis material.

I have a fully modded Model 1.5 here for comparison, and the Model 7 in the photos comfortably outperforms it.

brilliant , thanks for that
