Gorgeous and impeccably crafted 300B speaker and headphone amp from ampsandsound, the Agartha 2021. As a headphone amp it drives the most demanding large planars exceptionally. I've tested loads of amps with the Hifiman Susvara and this is my out and out favorite. Having multiple impedance taps is awesome for optimal headphone matching. As a speaker amp it shows off that 300B magic and is best paired with high efficiency speakers. Swapping the input tube allows you to tweak the presentation to your preference. There are lots of 300B options in production these days so great upgrade options there as well. The unit is in great condition. There is a little paint chipping off the back foot of the largest transformer. This is unnoticeable from almost any angle but wanted to call it out.

Ships in its original (and rather huge) flight case with a complete tube compliment.

At my asking price I will cover the significant (~$300) shipping cost to deliver this beauty insured to your door (contiguous us).

Let me know if you have any questions. I've got plenty of good feedback here and on US Audio Mart.
