Gee, what started as a simple thread is now getting exciting, love it when I learn stuff.
First, Ralphie, PLEASE keep us updated on all thing related to your new listening space, pictures and text would be great. I know you and I know it will be fantastic.
I will add just a tiny bit as it makes me sick as to all that I did. I have a low level hum, it does not turn up or down with volume. As soon as speakers are engaged with sound I cannot hear it at all.
My only analog is the RCA cables that come out of external Exasound MCH DAC to my 7.1 section in back of my McIntosh MX122.
My McIntosh C1 1100 Pre Amp is hybrid tube and digital. But I bought that after so that does not count.
I disconected everything. I have a dedicated eletric panel just for my equipment.
I even bought a new MX122 with a $1200.00 restocking fee, because it was convinced it was the MX122, I paid the restocking fee.
I have all the connectors, cables, blah, blah.
My room 12' X 14' is very quiet, dead quiet. When I do my meditation in morning I hear the hum of the Niagra 5000 power supply, when everything is off.
Do not buy a Niagra 5000 powersupply. In the instruction list, it says" This unit will have a low level hum and is considered normal", something like that, WTF, that pissed me off.
However I connected two speakers to MX122 only, no amps, no power supply, no nothing, no music, and still got low level hum.
I have a dedicated fanless PC in the chain, and added a Furman power supply just for the PC and that helped.
Sometimes I wonder, if it is the speakers themselves, but I don't think so? I have all matching B&W Diamond series, 9 of them.
Off subject: I am seriously starting to reserch Kplisch La Scala AL5's, not because of anything, but having my B&W 804D3 as my main two fronts, I am strating not to like the brightness of that little dome tweeter. I think my Tinitus gets activated with certain speakers. Anyway I always do lots of reserach before anything.
Back On Subject: Can your crossover settings create a low level hum?
I think I don't like Audessy anymore? Maybe a DIRAC room correction would be better?
Ask me anything, likely I did it.
The best success was that I let it go, and for the most part it is gone. When I first got tinitus, mostly in my right ear, it made me crazy, I heard it all the time, now 3-4 years later I barely hear it at all, unless I want to.
