@kingbr -- I hope you find out the issue, but if I were in your shoes, I would NOT continue to risk my SF Sonetto's. For goodness sakes, disconnect those speakers ASAP. If you want to continue to experiment with possible issues, connect the cheapest pieces of crap you can buy tomorrow off of Craigslist. I've seen permanent damage done to high end speakers due to an ongoing sudden "pop" from the amp. It baffles me that some brands accept a "power on pop" as normal or OK. I'm not an electrical engineer expert or speaker driver manufacturer, but that sudden "pop" can't be good...it just can't. Just my two cents worth. Keep us updated!
Loud pop/screech when powering on amp
Hello All,
I have an Audio Refinement Multi 5. I just bought her used in pristine condition a couple months ago. I get a loud pop when I turn it on. But the last couple of days there's almost like a weird screeching sound right after the pop . Everything sounds. fine when I play music/movies, but I'm a little concerned if this is a bad sign. I'm also a little concerned if this is harming my speaks. I have had other amps that pop and I know this is normal. I always turn her on last and turn her off first and volume is always low when powering on and off. I only use the power button in the front when done for the night. I have not turned the main power button off since connecting her. I have a Shunyata power cable plugged directly into the wall on the amp. I have an Audioquest Powerquest 303, should I maybe try plugging the amp into that, would that help? I also did turn off the main power switch on the back this morning and will try when I get home to see if this helps when I power her up...
Thanks in advance for any advice...
Best Regards...
