Michi P5 Preamp Tone control Distortion

Even Rotel preamp lines carry exact same unsolved tone control humming issue as well. I had RC-1590 and RC-1572 both have same problem but no further firmware update to address it. I guess nobody cares about it ...

@larrymanadgn you’re exactly right I have RC1590 too and is piece of crap it will make a loud pop sound when my ceiling fan is turned on and off 
makes all this unnecessary hum noise 
aesthetically Rotel makes gorgeous looking  products especially when I compare with my previous Parasound P6  but they’re crap 

..Interesting no reviewers or worse the factory missed it  quality control  no  and I would bet its a hardware issues and wont be fixed due to complete design issues  boy I am happy  was going to buy one..perhaps its a easy fix  its a well build unit hope its not a big issue

 

Hi all, know this post is old. Has this tone control issue been fixed? I'm having trouble finding any info on it.

I'm about to pull the trigger on a new P5 clearance.

@pdjmwj If you’re using tone controls there’s something much more seriously wrong with your system or room that should be addressed before resorting to tone controls.  Just my $0.02 FWIW.
