The Concero 65 Series
The Concero 65 monoblock power amplifier series come in 3 versions, the Reference, the Signature and the highest level – the Limited Edition.
The Concero 65 Limited Edition descends from our Legend Series Achilleas amplifier, based on our 813 driving 813 circuit topology.
The Concero 65 Reference and Concero 65 Signature are both smaller versions of the Exsequor monoblock power amplifier, which is our top level 814 driving 813 circuit topology.
The 813 Tube
The Concero 65 Ref uses a parallel pair of RCA 813 tubes in the output stage. As an output tube, we believe this tube is one of the most linear tubes ever built. Triode curves quality are unmatched even by the most linear 300B tubes for example. And of course most bigger triodes like the 833 are far behind in both linearity and sonic performance.
This 813 big bottle tube never seizes to impress us whenever we compare it in our labs with ANY power tube used today, and is our weapon of choice when designing SOTA SET amplifiers.
Driver stage
The driver stage uses it’s own PSUs and special biasing circuits. The driver stage is built like as a small SET amplifier driving the output stage using a unique interstage transformer. A sample of the driver’s capabilities it the fact that it can deliver 14W of power if needed. The output stage is driven in absolute fidelity of the input signal.
Filaments
All three DH tubes,output and driver are using triple PI filters with a total of 700,000uF of capacitance,giving a completely ripple and noise free filament current.
Driver and Output PSU
All PSU are independent using their own transformers,chokes and our proprietary Super Capacitors. This unique type of film capacitors present a set of specifications unprecedented in capacitors used in audio, such as ESR and ESL values 100 times lower than electrolytics, as well as a maximum current surge measured in Kiloamperes.
Biasing circuits
Both driver and output stage as biased with our custom biasing circuits, with all tubes monitored and biased on the fly. There is no need for external instruments. Using the biasing monitor system, a user can fine tune the amplifier sonic wise, to suit the system – on the fly, and while music is playing.
