Try a variac, lower power=lower hum. Its very efficient with the leben CS 300 and the right chanel noise.
Leben cs300xs electrical noise in tweeters?
Hi!, I have a Leben cs300xs amp and I like the sound, but I discovered that the amplifier produces a little "electrical" noise in the tweeters of the speakers ( philips miniwatt with 91dB) if my ears are in tweeter... This is normal?.... Another owners of the Leben with the same experience?.... Thank you!
