100%, been saying it for years, it's all about the current. Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

So.........I'm wondering how much current is considered adequate and is it all created equally? Is tube current the same as ss current?

"I'm wondering how much current is considered adequate "
An example might help. Current (amperes) is equal to the square root of the power (watts) divided by the impedance (ohms). So, if we look at producing 350 watts into an 8 ohm speaker that would be the square root of 350/8 which would be 6.6 amperes times 2 (for stereo) which would be 13.2 amperes. This would be for an RMS measurement the peak requirement would be 18.7 amperes (Peak Current = RMS Current x 1.414). So with a power of 350 watts into an 8 ohm impedance the peak stereo demand would be 19 or 20 amperes. 
That's the thing about discussions concerning Amperes  they're always current.
If loudspeaker designers hadn't all gone sadistic back ca. the late 1970s and given us loudspeakers with ridiculously low impedance dips and outrageous phase angles  current would be less of a thing to worry about.
now, if you'll excuse me, those darned hooligan kids are out on my lawn  again!


I'm glad I put 14 gauge wire and 20 amp rated outlets in my cottage.Most people just listen to music and watch movies. I EXPERIENCE them.

So now your wire is the fuse....should you plug a 20amp something into it.

Anything less than 200 Amps is not enough😅 Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

Wow I cut it pretty close there.

Maybe I used 12 gauge.

.......and the 1st watt is the most important
H9"Appreciation of audio is a completely subjective human experience. Measurements can provide a measure of insight, but are no substitute for human judgment. Why are we looking to reduce a subjective experience to objective criteria anyway? The subtleties of music and audio reproduction are for those who appreciate it. Differentiation by numbers is for those who do not".Nelson Pass Pass Aleph 30  EE Avant Pre  EE Mini Max Plus DAC  MIT Shotgun S3  Pangea AC14SE MKII  Legend L600  BlueSound Node 3  Tubes add soul!

... or the first 100 milliwatts for those of us with 104ish dB/watt @ 1 meter loudspeakers.

Yeah, 14gauge wire is for lighting circuits. It's only real value is being able to have an acceptable number of conductors in a switch box to follow code.
Receptacles should have 20amp breakers and 12gauge wire. For a dedicated power amp circuit, I would recommend 30amp breakers and 10gauge wire.

I have three 20 amp lines with 10 gauge wires. Two of the lines are for the amps (one line for each amp), and the third is for the other gear. Before I put each amp on its own line I kept popping the breaker on the circuit for the amps. After adding another line so that each amp had its own line I no longer popped any breakers. However, I did break both speakers one night, but the amps kept on working.Lumin X1 file player, Westminster Labs interconnect cable

I have forgotten the cost of the drivers. Probably a few hundred dollars for each one.Lumin X1 file player, Westminster Labs interconnect cable
