It is a pure tube design, utilizing 6C45 tubes in a class-A, single-ended topology, with transformer coupled outputs. There are no semiconductors used in the entire amplification path. The D/A converter is designed to be capable of up to 24-bit/384k sampling rates. This maintains pure data integrity, which is transmitted via standard high speed USB 2.0 interface operating in asynchronous mode.

The high quality construction features include a pair of Nickel Alloy core output transformers, all-aluminum chassis with no screws visible from any viewing angles, a remote-controlled linear external power supply for amplification circuitries, a custom built toroidal power transformer, and multi-layer military grade PCBs.

The dedicated port for in-ear-monitors carries a full range of volume controls ensuring minimal noise. Despite its incredibly compact size, “Fireflies” is a power-house with the capacity to drive almost any demanding audiophile headphones. To accommodate different system setup needs, “Fireflies” can also be used as a stand-alone D-A Converter.

One (1) year limited warranty cover amplifier and power supply parts and defects, thirty (30) days for tubes. No coverage on glass except for defects on arrival.
