Amp ac cable connection

... I am talking about the products that serve as intermediaries between the wall receptacle and the equipments’ power cords that claim to provide surge protection via sacrificial MOVs (90%+ of them I estimate) ...

MOV devices get a bad rap here. Without wading into that controversy, an MOV does not inherently limit normal current.  (Obviously, they are designed to limit surges.) Some AC protection or conditioning devices are blamed for having a negative effect on audio quality, so many audiophiles blame "current limiting" for that. In practice, most don't actually limit current when properly used.

What constitutes proper use is also the subject of some debate. For components such as isolation xformers, I wouldn't use them at more than half of their rated capacity, especially when connected to a power amplifier.

The place for a surge protector is on your TV cable line (only, unless you like choking the current flow to your audio system).

Sorry, but this is mistaken. The notion that all surge protectors are "choking the current flow to your audio system" is simply misinformed.

A surge protector on your cable TV line offers no protection to your audio equipment. It also offers no protection from a lightning strike.

To protect from a lightning surge - which is clearing the most dangerous to electronic equipment - you can't do better than a Type 1 device. The Leviton 50240-MSA is probably as good as any for this use, and it does not limit current. Oddly, not all utilities allow Type 1 devices to be installed in their meter panels.

A Type 2 surge protector will also not limit current.

Some Type 3 devices do limit current, but not nearly so much as many audiophiles suspect. This can be shown by measuring the device's output under load.

... With the power cable plugged directly into the wall you are hearing your equipments full potential ...

That wouldn’t be true if the voltage is too high, or too low, for the amplifier to work properly. What about power factor? If the AC service has bad power factor, that could rob the amplifier of the current it needs to reach rated output. What if there’s hash or distortion on the AC line? Not all amplifiers are equally able to filter such noise.

The value of a power conditioner depends a lot not only on the conditioner itself, but on the quality of the AC line and the system’s other components.

Through psinyc own listing session he is supporting what I am saying. Power conditioners restrict the full potential of your equipment

I'm not sure what you mean by "full potential." I can tell you - with measurements to support it - that faulty AC power can limit the performance of audio equipment - especially power amplifiers - and that the right power conditioner can restore performance. That's especially true when the AC line has a bad power factor.

This isn't mumbo-jumbo, but very basic stuff.
