Direct Heated Triodes (DHT) are prized for their exceptional transparency and harmonic richness. By operating without feedback, the Agartha Rev 2 delivers a highly organic, natural sound with the signature warm mid-range bloom that single-ended tube amplifiers are famous for.

The variable input transformers allow you to choose between 1v:2v or 4v:2v configurations. This flexibility helps you match the amplifier's gain structure to your specific DAC or source component, ensuring optimal signal-to-noise performance and volume control range.

The Agartha Rev 2 features a redesigned input stage using 12AX7/12AU7 tubes and a massive power supply with a dedicated choke. These upgrades significantly lower the noise floor, making it well-suited for a wide range of headphones, though performance may vary depending on the extreme sensitivity of your specific pair.

Yes, with 7 watts RMS at 8 ohms and 5 watts RMS at 32 ohms, this amplifier has substantial power reserves. It is designed to handle a variety of headphone loads, including power-hungry planar magnetic models, while maintaining its characteristic wide bandwidth.

As with any tube-based amplifier, you will eventually need to replace the tubes as they wear out over time. The Agartha Rev 2 uses common 12AX7/12AU7 family tubes for the input stage, which are widely available and easy to source for future replacements.

The Agartha Rev 2 is a substantial piece of equipment with a wood chassis measuring 15.75 inches wide by 9.75 inches deep. You should ensure your desk or rack has enough surface area to accommodate its footprint and provide adequate ventilation for the tubes.
