High Fidelity Three Tube Amplifier HiFi Power Amplifier Tone Board Symmetrical Complementary Dual Differential Input Home Use

I tried it out last night and let it run in while I slept. This morning, I gave it another test, and overall, it's pretty good. The sound is well-balanced across all frequencies, and the soundstage is wide. Compared to the Marantz PM6007, they are quite similar. The Marantz has a brighter sound, especially with vocals, while this one has more power due to its higher wattage. Overall, it's great for listening to Jay Chou's songs, where you can hear clear vocals and rhythm without any muddiness. I also compared it to the STK4040VI, and this one has a wider soundstage and clearer sound. I tested it with Fyne Audio F301 speakers, which are known for their clarity, unlike older Sony speakers. In summary, it performs beautifully! It outshines the LM3886 and LM1875, which are great for vocals and have high cost-performance. The STK4040VI and 350 are also good, but this one has a wider soundstage and clearer sound, making it very suitable for Japanese speakers. The vocals are warm and pleasant, and the bass is quite strong. The NAD316 also sounds good with a warm British tone. Overall, I'm really pleased with this product!
