Hi! I often complained about my current problems here in the forum at just 420w rms from my next q.22. the next is now, (passed before 3 weeks), the mains unit burned through. a good replacement for as little money as possible had to come and found a used ESX Q120. Is an older of ZED audio and simply great. but what I initially suspected that my current problems might get worse was not so. it is even no light flickering anymore, although the new level I could imagine 3 reasons for this but are only conjectures, what do you think about it? 1.) I drive without light on the day, since the beginning of the year and thus the battery can be charged better 2.) I was on the road 3 weeks without sub-stage, but the battery is now fully charged. 3.) because the new stage has more power, it may not have to develop its full potential to exceed the loudness of the next. the reason is that the next stage has more power. it’s also about a lot louder than before. where the light would have already weakened in feeling does not do anything now and you can turn even louder without what would be noticeable in the light, in addition it blows out the ears. really horny but the most important for me and that surprised me the most is the very good sound.
