I've found the ART Dualxdirect to be a reliable and versatile tool in my audio setup. It's well-made and works seamlessly with either battery or 48v supply. The ground lift and attenuator features have been particularly useful in reducing hum and signal noise. I've used it as a DI, splitter, and extender, and it's performed admirably in each role. The sound quality is clean and transparent, although I have noticed some slight signal loss when using the attenuator. Overall, it's a solid addition to my rig, and I appreciate its compact design and ease of use. I've had some instances of earth hum, but the ground lift feature has helped to mitigate this issue. As a DI box, it's been handy in many situations, and I've been impressed with its stability and reliability.
