MUZISHARE X9 300B single ended Class A tube integrated Amplifier with Phono MM

This is the 5th tube amp I have purchased from China-hifi. I have never had any issues with any of their products. I have upgraded each purchase. This is by far the best amp to date. Detailed, separation, sound stage, lush mids and highs. Build quality is excellent. You can't purchase an amp of this caliber in the states for anything close to this price. I had an issue with a defective tube. I emailed Sofia and had a response within 12hrs. They are sending a new tube. You can't get better customer than that.
