But for owners of speakers that still elude the powerful Jota monoblocks, Art Audio has created the 60-watt Adagio SET monoblocks, or for yet more power, the mighty 150w pure Class A Opus Ten push-pull monoblocks that will drive virtually any speaker under the sun.

Why tube rectification?
All amplifier must convert the alternating current from the wall to direct current. Traditionally, inexpensive silicon diode rectifiers perform this job. For best sonic performance in our tube amplifiers, we much prefer old-fashioned but costier vacuum tube rectification. In instances where we need to increase current capability to properly support the chosen output tubes (as with the Jota for example) we start with solid state rectification, then place a tube rectifier in series to capture its sonic advantages regardless.

Auto bias
All Art Audio amplifiers use sophisticated auto biasing so no voltmeters, screw drivers or user maintenance is ever required. Once the tubes have been installed, the amps need to merely be turned on or off. If tubes are due for replacement, they can be simply inserted without any adjustments.
