ā The close of 2021 has brought out more than 18 months of a global pandemic. During these challenging times, we at ampsandsound strengthened our development efforts resulting in new generation of our classic amps.
Although the Agratha shares its name with our legacy 300B offering, little is the same. These times of challenges gave the focus to improve all aspects of the beloved amp; including both subtle and significant changes alike. Notable takeaways include increased power output, reduced noise floor across all our amps, increased bandwidth.
The ampsandsound Agartha brings the legendary Direct Heated Triode sound of 300B Triodes to personal audio. We returned to the 300b due to significant improvements in new manufactured offerings. Combining a single gain stage, zero feedback, and careful attention to grounding techniques, we can use a the Large 300B Triode with headphones without hum or noise.
The Agartha tube amp pairs a 6SL7 tube for the front end with tube rectification enabling excellent 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 680mV at the idle, and stable output of 5 watts RMS into an 8ohm load and 3 .5watts into a 32ohm headphone. Frequency response is 12hz to 34hz at 1 watt, 1-dB. Carefully selected output iron reduces distortion and increases frequency response. And of course, we also use our 5% capacitors and 2% resistors.
The motivation of the Agartha is to provide wide bandwidth and give the warm mid-range bloom that is at the heart of single-ended direct-heated triode designs. Tube set included.
