The Jota amplifier has been among Art Audio’s offerings for a long time. The machine is available in many different versions to be very versatile and while certain details have been tweaked over time, the core platform has remained the same for years.
To appropriate a famous slogan, the Art Audio Jota gets my vote as the ultimate driving machine. It transports me into the music in a way that’s intrinsically emotional, like a direct injection of adrenaline that instantly enhances one’s sense of energy and well-being.
The Art Audio Jota Sentry is a classic SET (Single Ended Triode) amplifier. The audio path is built based on three tubes – two double triodes in the input and control stage and a power triode in the power stage.
The Jota shows its hi-end soul to perfection. This is a fantastic, very well-tuned amplifier with a sound that ties it to the best amplifiers in the world known to me: the PAT-777 Harmonix/Reimyo and Ancient Audio Silver Grand Mono amplifiers.
The sonic balance for the Jota was set in an incredibly tasty way. One obtains fantastic vividness and very good resolution. The Reimyo and Ancient Audio machines—each in their own way—go a step further but those are not big differences.
The ART Audio Jota SET Stereo Amplifier, High Current version, brings a goodly taste of the quality SET experience to the realm of medium efficiency speakers. Its treble is a model of proper voicing, always subservient to the whole and never calling attention to itself.
In light of popular SET notions, I find it vital to stress that this 52BX-outfitted Art Audio amplifier -- without support from a suitable preamp but outfitted with an optional GoldPoint attenuator -- had no trouble whatsoever controlling the challenging load of the Hales Transcendence Eights.
