Review on Nobsound 12AX7 12AU7 Vacuum Tube Preamp HiFi Preamplifier - Unleash Audiophile Excellence! by Elsa Lynch

When I first ordered this box I was suspicious of this box given the price but was amazed when I turned it on. This is an absolute gem for the price. Even with original Chinese tubes, the sound was rich, warm and meaty. And with four inputs, there's plenty of room for components (but no phono stage). The box itself is a solid piece of metal sandwiched between handsome blocks of wood and topped with massive knobs and switches. I was a little worried it would look like a toy but it is a rock. Although no frills, absolutely no writing on the keys or inputs and instructions in Chinese. Luckily, it's such a spartan technique that it's pretty obvious to those who don't speak. However, follow these instructions and read them carefully when laying pipes. 12au& and 12ax7B tubes are easy to confuse.
