The problem with putting everything under the lid is heat. Electronics don’t live long at elevated temps and some amps for
Instance run to hot and simply would not survive without ventilation.
Some recievers run way to
hot also and many give out in a few years because of it. A some point you would need your conrol preamp
or head unit to control volume/source selections etc.  and that unit would need  to be out in the open anyway

A smoked dark glass front to hide everything with an open back or even fans of some kind (12v quiet computer fans) would go a long way
toward a longer life

Exactly right.  Closed off, unventilated areas will cook your equipment.

Oh yes, I have no plans of doing this without adequate ventilation to my audio components. I'm primarily interested in whether or not such a space would provide an oppertunity to block out RF noise or if such measures would be counter productive to sound quality.

I would digest this information and figure out what is practical to incorporate in your environment.

Nice...thanks for this. :thumb:   I'm discovering a lot of things about my house and I think a completely new breaker box will end up getting installed.

Lately, I've been finding some home theater enthusiast as well as some audiophiles taking advantage of the 240 volts of balanced power available in every American home. Most equipment today is capable of running at 240 volts. If it uses a linear supply, it usually has two taps on the transformer and a voltage switch somewhere on the unit. The switch can be set to 115 volts or 230 volts (+/- 10%). If it has a switching power supply, it can utilize anything from 90 to 250 volts without making any changes.

Most amplifiers will actually output a little more power when connected to 240 volts. This is highly recommended for large mono blocks and subwoofers. Since the power is balanced, it also has a lower noise floor. Anyone who is running a dedicated line might want to consider this.
 
Some audiophile grade isolation transformers can also be configured for 240 volts in and 120 volts out. Then you can keep any power conditioners, distribution strips, and power cables you already have and still take advantage of the 240 volts available in your house.

My thoughts on a US 240 Volt system.
a] For a large high power home theater system, it may be worth the work.
b] Many source or control components can't be converted. So interconnects between 120 Volt units and 240 Volt units might be tricky.
c] 240 Volts means twice the voltage and half the current. Also half the noise current which is good.
