Thanks ot ALL for your input. I don't quite know yet what to make of this, but DO see plenty of system owner with multiple circuits. This I'll take to be a good sign. Lots of people buy cables that cost $10k each or don't get vaccinations. I don't see any scientific conclusions to draw from that. Still waiting to see some actual research or hear from a design engineer.
All of the higher end Emotiva amps spec "Between 100 VAC and 250 VAC @ 50 / 60 Hz (automatically detected)" so I don't see how a 7-8V drop is too much. Even their low-end amps spec 115VAC.
-tm
Why do people AUTOMATICALLY go to the wacky end of the cable world? Who does spend that kind of $$ of cable but someone with LOTS of surplus wealth? Certainly nobody I know. Several 'value' brands exist which stress fundamentals rather than esoteric claims. And don't cost an arm and a leg. If I even THOUGHT I had 5000$ to spend on cables, I'd instead spend a month in Hawaii, kicking back on the beach and hiking. It'd be like not buying a car unless it cost 80,000$, or More. Dropping an extra circuit for amps only.....or amps and sub, is certainly NOT a deal breaker. My extra circuit is serviced by a PSAudio Soloist outlet. And certainly LISTEN to those engineers. They know good sound, don't they? Totally ignore the contrary-evidence provided by countless persons reporting changes, usually for the better, (but not always!) when upgrading cables and power cords. The 100vac to 250vac spec for EMO amps are ALL those with switchers. I honestly don't know what common practice is for amps with linear supplies. You can make different versions for different markets? Others have a switchable voltage selector which implies 2 sets of primary windings on the power transformer, like my Parasound amps. And BTW, the specs for those 'D' amps CHANGE as a function of input voltage. You'll have to look up some B&O Datasheets. I'd start with ASC series. One other consideration is that of power factor. If your PF is below about 0.8, that could be an issue. Dont' forget you are REALLY using VA while getting billed for Watts. Voltage drop I think causes an increase in current. Small? yes, and probably not a deal breaker unless at the extreme end. I frankly don't care WHAT you do. Get one of those Octopus Connectors and have at. I've had enough weird stuff happen to place some weight on what I hear rather than what I'm TOLD I Should Hear. elementarysafety.com/colouring-page/coloring-Electrical-Safety/electrical-octopus |

I never said installing an outlet is the same as using an esoteric cable. I said there are lots of foolish people out there so I’m not blindly following what the masses on the Internet spout.
On top of that, there are things like confirmation bias. Show me some research, blind testing, expert analysis.
If you can’t trust the engineer designing your amp to have a good ear for sound coming out of it, then you’re in trouble...
Again, I would have gladly done it for my setup at the right price. However, given the cost of retrofitting, I believe I could get better benefit with that money invested elsewhere.

Do you know AnyThing about DBT? I'd go so far as to call it impossible to do with stereo.
Even doing what I did for a living, designing an experiment to test for 3 or 4 variables entails LOTS of tests and than
evaluation is strictly measureable.
Please give me some insight on organizing DBT for stereo. concept? Easy. Acutally doing it? Extremely difficult.
Only a few amp designers listen. Pass, among others, seems to have pretty good hearing for MUSIC.
I'd put Curl in that categor as well as D'agonstino, founder of Krell. PSAudio has a couple amps designed by Basom H. King.
I heard early versions at a show and was impressed. Also fairly $$.
Almost Forgot about Bob Carver, who seems at times to have his OWN set of priorities.
Sure, invest elsewhere. Starting with the room. Depending on goals, you can apply DIY there, too, and to great effect.
And millst, you are a real Spec Guy. Just keep in mind that everythig that can be measured doesnt' matter and everything that matters
can't be meaured.
Many 'perfect' components which were very highly spec'd have simply disappeared off the face of the planet.
Even the first Gen SONY CD player which 'shared' the DAC between L/R disappeared immediately when people decided it simply didnt' SOUND right.
I have no idea how well it measured.
Depending on your system, where you live, and goals, it isn't really a bad idea to have an additional circuit. That's what I settled on when getting set for the long haul.
ONE additional circuit used for amps / sub only. Speakers if you read my call-out are very low sensitivity panels and have a 200x2 (@4ohms) amp for each.
