Nonsense! 'Romex' is Southwire brand Romex® everything else is generic NM-B (Non Metallic-B). NEC/UL have very tight specs for conductors. Does Oyaide wire even have a 'UL' listing? Does Oyaide wire even make an in-wall AC cable? I only see flexible cords. That UL info: UL reference number...

Real Southwire brand Romex® is about as good as it gets.

At the main breaker panel the Neutral to Safety Ground voltage should be 0.0 Volts.

Audiophiles often use 'DC blockers' as a solution in search of a problem. There as to be a DC offset on the AC power line for them to do anything. Something big has to be creating the offset and many big AC power users don't run 24/7. For others: So does the transformer hum change from time...

There are people with skill that can do tasks like this. One of my engineering co-workers had this skill. He did part time camera lens repair. When a screw on my eye-glasses broke, he un-wound the small screw like a spring.

Did you try a shorting plug on the RCA input?

Only if the interconnects or speaker cables are well chosen for the task at hand is this true. While all good interconnects and speaker cables sound the same, there are many that are not good cables. There is very little correlation between price and goodness (above the freebee point).

Yep, lightning is weird unpredictable stuff. I don't put much weight into any anecdotal reports because lightning doesn't view their house the was they do. Electronic equipment is often damaged because the cable TV/internet cable has one ground rod and the remainder of the house has the main...

The power company installed unit at the meter and the Siemens unit at the service entrance will have about equal effectiveness. I receive e-mail ads from the power company about rental of the meter unit. The monthly charge in each as is different and after 5 years it's a lot of money. The...

The answer is way above my pay grade. Maybe because even young children have their own cell-phone or i-pad. I joined the linked forum over 15 years ago. Back then everyone wanted to build a home theater. Later members noted that a home theater room did not add to the resale value of their home...

Wrist watches are no longer 'waterproof' they are now 'water resistant'. So too for residential listening rooms, they are not soundproof but sound resistant. Never read about the above construction, most rooms use 'Green Glue' techniques. A decade ago, everyone was building home theaters and...

Well no. Racing fuel does have a purpose in a race car. Audiophile fuses have no special abilities.

Oh dear, oh dear. You can't test a receptacle with a voltage test like that. That is a circuit test and the difference depends (mostly) on how much current is flowing thru the circuit. The more current, the more voltage drop on the Neutral. There should be no current flowing on the Safety...

That sounds like a great setup for a large top-shelf system (with 7200 Watts available continuously for over 3 hours). Large isolation (or balanced) transformers wired as Separately Derived Systems are a wonderful pricey AC power solution. But balanced transformers bring with them a lot of...

Well if it's not an opinion, then it sure is an oversimplification. Humans are rather sensitive to small changes in light brightness. So if the lighting and amps are on the same circuit the possible change in audio power may be trivial.

In the US, you can't use 15 or 20 Amp receptacles in a 30 Amp circuit. Doubt that there are many amps designed for 120V 30 Amp circuits. * * * * * * * * * * * * * * continuing; if you were to run a 30 or 40 Amp feeder from the main breaker box to a small 6 breaker box near the listening room...

That 80% number is a design guide, say for a large lighting or heating system. The circuit breaker rating is it's continuous 3 hour rating. It's short time period capability is much greater. Some home theater people have been surprised at the number of big power amps that can be played real...

OK, so here is the difference. Twice the AC line voltage means one half the amperage. In power line circuits, noise is current rather than voltage, so there is less noise current. But any well designed hi-fi product well be able to deal with it, so the sound quality will remain the same.

Breakers may not last forever, especially if they are overloaded (and tripped) by other appliances on the circuit.

Any 15 or 20 Amp residential circuit can easily deal with that momentary spike. The 15 & 20 Amp ratings are for a continuous 3 hour period. The breakers have some built-in time delay. An old fashioned 15A incandescent lighting circuit (say in a store) would draw a momentary 150 Amps at turn-on.
