xDuoo has been on a streak recently with their range of new products that all target different users and niches. The MT-603 is the latest addition, a pre-amplifier with 4 front-facing Toneluck mechanical switches that provide satisfying feedback and allow the user to quickly and easily switch between multiple sources. xDuoo dub this an “airport for your Aux cables”, providing convenient switching alongside tube amplification goodness for all. It uses a nine-pin 12AU7 vacuum tube and hot-swap socket for tube rolling to listener preference.
The MT-603 is available for $109 USD at the time of writing. You can read all about it and treat yourself to a unit on Apos Audio!
