An Airport For Your Aux Cables
If you’re swimming in aux cables from all of your analog devices, you’re going to love the xDuoo MT-603. Connect all of your analog sources for fast and convenient switching, while enjoying the benefits of tube amplification.
3 RCA input ports
Connect a turntable, CD player, cassette player, radio, or other RCA-equipped unit into one of the MT-603’s four RCA inputs and then run them to a single amp.
Warm tube pre-amplification
There are many benefits to tube pre-amplification, like boosting a weak signal before it reaches your amplifier or adding the warm tube sound to a solid state amplifier. The MT-603 uses a nine-pin 12AU7 vacuum tube. A classic of the tube world, the 12AU7 is easily replaced and rolled.
Toneluck switches
Chunk. Clunk. Is there anything more satisfying than analog switches? Enjoy highly-durable, highly-satisfying switching with the MT-603’s TONELUCK switches.
Aluminum alloy shell
There’s more than meets the eye with this pre-amp. A sandblasted aluminum alloy shell is a delight to operate, providing long-lasting protection and style.
