Hi there, problem is during quick loud dynamics during a film my amp(technics su-a900m11 shuts down so only my processor(yam e800) is still working, bloody annoying.If I set the Yam to standard not max setting for dynamics the system plays louder but has'nt enough punch. Also tried setting the LFE below 90hz to go to the sub(shame I hav'nt got one yet,money) it still shuts down. I did have a pair of TDL RTL2's but I killed them,bought Eltax symphony 6.2's but changed them for Liberty 5+'s, both pairs shut down, but the TDL's did not, dern, dern, dern. Is my amp at fault or do you think the speakers are drawing so much current they cause the amp's protective circuit to cut in. Do you suggest I change the amp, the speakers or buy a d/d amp. Your advice/suggestions would be most welcome. Philmate.
