Exsequor Tube Reference Amplifier
Working in Class A1, the Exsequor amplifier can deliver more than 65W in 8ohm or 4ohm loads. With it’s unsurpassed clarity, 3D imaging and breathtaking transients, with enough power to drive almost any floorstanding speaker, this SET amplifier is a class of it’s own.
We believe that SE non feedback amplification stages deliver the best overall sonic performance to the listener. Yet, almost all SET amplifiers do not have sufficient power to drive the majority of modern loudspeakers. One way of delivering enough power from a SET amplifier, is the use of many parallel mainstream tubes like KT-88, EL34 or big bottle tubes like 845 and the 805.
Direct heated triodes with their super smooth sound are the way to go. The tube of our choice is the 813, a 50W thoriated Tungsten filament tube with it’s 125W plate dissipation rating and probably the best big bottle tube sound we have ever tried in our labs, leaving far behind any version of 845 and 300B tubes we ever tried. Almost all tube amplifier manufacturers with their light, slow and weak power supplies, give a distinct flabby sound to the majority of these amps. They get things worst by trying to drive the big output valve with small signal tube like 12AXXs e.t.c. As a result, the output tube, is underdriven with the known results of limited frequency response and lack of acceptable transient response..
We chose to differ…
. The Exsequor monoblock tube amplifier is our opinion of how a SET amplifier without compromises should sound and how tube amplification should be implemented.
