Noise is the enemy. Ask any schizophrenic.

I was going to stay away from this thread but have decided otherwise :thumb:
1) I have a Dedicated 20A Breaker > Emotiva CMX-2 > Panamax MR4300 and Emotiva CMX-6 setup and you can put it on an oscilloscope (and I have) to see the difference (for the better).
2) I have a Littmann CORE stethoscope. It has 40x amplification. Put it in your ears, listen to any component (amp, speakers, whatever) and you hear silence.
3) I've tried balanced power. There is an obvious difference. Can hear it in a blind test 100 percent of the time. It boils down to preference. All of my gear manufacturers tell me if I use it it will void the warranty (which I'm out of anyway). I've opted to avoid balanced.
Happy listening and Happy New Year to all. :)

As we often find in this hobby, not everything can be measured, or what we measure is not what we hear, and what measures perfectly can sound shitty. I know there are a hundred other observations on measurements vs what we like to hear…

Joni Mitchell was right: You don't know what you've got 'til it's gone...
Noise in audio is a multi-headed beast.
We have 60 cycle (120Hz component) and it is easily measurable at every multiple
We have:
intermodulation distortion
Transient intermodulation distortion
Comb filtering
Heterodyning
EMI distortion :thumb:
RFI distortion
Back EMF from other gear, especially digital sources
Current limiting
Dynamic compression
Dielectric absorption induced ringing
Dissipation factor time smear
VoP issues
Shitty wire
Brown outs
...
And on and on...
All I know is that when any or all of these are in play, music suffers.
