Know before you buy
While traditional SET amplifiers often struggle with dynamics and power delivery, the Concero 25 uses advanced engineering to provide a muscular, high-fidelity sound that retains the purity of a triode design without the typical limitations.
Yes, the Concero 25 allows you to adjust the output power between 20W and 25W by modifying the bias settings, giving you some flexibility in how the amplifier drives your speakers.
With 25 watts of power and an 8-ohm impedance rating, this amplifier performs best with high-sensitivity speakers that can fully benefit from the nuanced, low-distortion output of the 845 tube topology.
Each monoblock weighs 65kg (143.3 lbs) and consumes 200W at idle, so you will need a sturdy, dedicated equipment rack with ample ventilation to accommodate the size and heat dissipation requirements.
Yes, the Concero 25 provides two gain options: x1 or x7. This allows you to better match the amplifier's sensitivity to your specific preamplifier and overall system configuration.
Each monoblock utilizes one Elrog 845 output tube and one RCA 814 tube to achieve its signature sound, combining classic tube warmth with modern reliability.
