The name Agartha used to describe a city in the center of the world. The ampsandsound Agartha brings the legendary 300b to personal audio. They chose the 300b for its long history as the king of triodes. Combining a single gain stage, zero feedback and careful attention to grounding techniques they are able to use a 300b with headphones without hum or noise. For those with headphone, horns or single driver speakers who are seeking audio nirvana, the Agartha is built with exacting attention to parts selection and implementation.
The Agartha tube amp pairs a 6SL7 tube for front end with SS rectification enabling great transient peeks, faster/livelier presentation and ultra-quite operation. The Agartha uses direct-heated triodes with zero feedback providing the classic single-ended sound so widely loved.
Typical of all ampsandsound amplifiers, the power supply is massive. This combined with a generous choke yields our trademark low noise; less than 3mv at idle, and stable output of 5 watts RMS into an 8ohm load and 1watt into a 32ohm headphone. Frequency response is 12hz to 30hz at 1 watts, 1-db. Output iron has been carefully selected to reduce distortion and increase frequency response. And of course we also use our 5% capacitors and 2% resistors.
The motivation of the Agartha is to provide access to the wide availability of NOS tubes and give the warm mid-range bloom that is at the heart of single-ended direct-heated triode designs. Tube set included.$3,600.00Headphone AmplifierBuy Now
