USB and Coaxial at the same time?
No but it would be weird and not a direct comparison. As soon as you connect the USB it may tru to take over the streamers clock. A better comparison will be to do each separately  
Is the problem end of life or the new processor?
Amps can last a very long time IF the power supply caps stay in good condition.  This is why you read so many questions here about getting amps recapped, and 20 years is about the minimum age these days. If you do have them recapped, ask for high... 
Impedance - The most ignored and useful measurement tool
Honestly, if anyone is interested, head over to DIYaudio were a lot over talented and helpful builders hang out. I didn't mean to start a whole conversation on impedance, just on how having basic diagnostic tools like this one can be really helpf... 
NSFW pop ups. C'mon Audiogon, get it together.
Personally I appreciate the porn like ads, how else would I learn what MILF stands for?  
Roon One Question
Yes, Roon can stream music from a file system.  It can also stream to your phone with a feature they call ARC.  
soft dome versus hard dome tweeters
@asctim DIYaudio is the best place to discuss mods to drivers, but I suggest you want a phase plug instead.  :)  
soft dome versus hard dome tweeters
@knotscott  Depends.  You should ask the fans, but one approach is to use a coaxial or coaxial-full range driver.  If you are willing to accept the beaming above a certain frequency though you can get get most of the benefits of being without a cr... 
Nuisance tripping of AFCI circuit breaker by inrush of current when turning on amplifiers
The only circumstance under which you should change the breaker amp rating to 20 A is if you have 12 gauge wiring already. Do not increase the amp size unless you are sure or rewire.  
soft dome versus hard dome tweeters
@asctim There is a design called "woofer-assisted wide-band" or WAWB for short.  It's exactly what you describe.  A wide band, such as a 4" driver that has credible output in the top octave along with a woofer that crosses in well below 500 Hz. Ch... 
Hegel hum?
Is the hum mechanical?  If so it can be related to DC in your AC.  Try turning off every other breaker in the home to try to locate it.   
Nuisance tripping of AFCI circuit breaker by inrush of current when turning on amplifiers
If it really is an AFCI tripping, consider swapping out power cords as well as changing the order of amplifier starts. I do repeat though, first generation AFCI breakers (1999 ish) were more jittery than the second generation CAFCI breakers.   
Nuisance tripping of AFCI circuit breaker by inrush of current when turning on amplifiers
I almost firgot.  Afci, cafci and gfci breakers include diagnostic LEDs.  If they arent on you have a plain old overcurrent trip.  
How can they not effect the sound
Depends where. For a dome tweeter a dent can do a lot of bad things. The use of a vacuum is a great fix. Also, with some tweeters the dome is removable and you can fix them by pressing from behind. This is the preferred solution with tweeters, as... 
Krell FPB 700CX
@invalid  It may have to do with the protection circuitry.  If you don't have a blocking capacitor it's a good idea to have some sort of amp and speaker protection circuitry.  Either detect DC and disconnect the inputs and outputs or adjust the b... 
SPEAKERS THAT SOUND ALIVE & DYNAMIC AT LOW LISTENING LEVELS
The benefit of ESLs and other planars comes from dispersion.  There's less reflected energy horizontally and vertically hence the proportion of direct sound to reflected is higher.  I hadn't really thought of this as a good low volume listening tr...
