All-in-One Tube Audio

Between your audio player and your headphones, several pieces of equipment can improve your sound. If you’re looking for signature tube warmth, you can get them all in one device: the TUBE-03MKII from FX Audio. This versatile audio solution can be used as a speaker preamp, headphone amp, Bluetooth receiver, and a DAC. Its warm and natural sound comes from a unique tube buffer circuit and two GE5654 tubes—but these can be replaced by 6J1, 6J4, 6AK5, 6K4 tubes for different sound signatures. The onboard headphone op-amp (OPA1656IDR) can also be replaced by higher-end op-amps like the MUSE02 or AD827. A QCC3008 Bluetooth 5.0 chip supports the aptX codec for reliable connectivity, while a well-regarded ESS9023 DAC chip delivers detailed conversion. Fine-tune your sound even further with onboard tone controls. 

Note: This run is for the TUBE-03MKII in black. All units come with a US power adapter.
