Review on 🔊 Enhance Your Audio Experience: HumanCentric Desktop Speakers with Tube Preamp and Bluetooth 5.0 by Josh Tadder

I just received these speakers today and they look very high quality and were packaged very securely. Setup was easy and while I haven't tested them in some sound scenarios, they sound good. But my question is, with a tube preamp, do I have to manually turn off the speakers every time they're not in use? I am interested in both the energy consumption and the lifespan of vacuum tubes. It would be helpful to have a more accessible power button and/or a setting that automatically turns off the speakers if they're not used after a set amount of time.
