Becaue it is a tube preamp.usually the amplifier needs warm time for 5-10 minutes, after that it can work in perfact status. NOTIC:for some new HiFi fans,the Preamp is not like power amplifier,you can not directly connect it to your speaker or headphone. Need connect it to Power amplifier.

TIPS:when you got the package. you need assemble the preamp board into blue box by youself. it's easy. then you can use it.
