Product: MUZISHARE X7 KT88 x4 Push-Pull Vacuum Tube Integrated Amp Power Amplifier MM Phono amp Remote Upgrade
Brand: MUZISHARE
Relevance: Substitute
Warm reminder: You should take about 100h time to operate the amp.RUN-IN to the amp gives it's best and stable sound.so during the first 100h use time the sound maybe is not the best,you can also use your own run-in method.
