I also have a 10 amp power conditioner (APC H10) that handles my turntable, tube phono preamp, line preamp, DAC, and CD player. When I had my Torii Mk IV also plugged in, it never once indicated overdraw, even at startup.

I looked through the Torii manual and didn't see a spec for power draw, but I think we can surmise it's less than 5 amps at all times or it would blow the fuse. I'd guess that after startup it's significantly less than 5 amps and that you're correct that the rest of your equipment combined draws even less.

All that said, my Torii sounded way better when I plugged it directly in to the wall. The rest of the components sounded the same or better run through the conditioner. The H10 is certainly not a high dollar/high spec conditioner, so it probably can't deliver the current needed by the Torii. Your surge unit may do a better job.

Don't do it.

The Tori Mark IV probably pulls less than 2 amps (120 V).  However, there is a good reason we spend money on a very heavy power cord.  An amplifier may average 200 watts but it needs access to very high currents for very short periods of time.  The traditional "surge protectors" and "power conditioners" don't allow the amp access to the power it needs and dynamis are lost, often heard first on bass.  

I use a PS Audio PP10, which is a regenerator and does not limit power at all.  It weighs 80 lbs.  

But your best bet is to plug it into the wall.  Do your own test on a sunny day (I assume you are worried about lightning).  Listen for 2 hours plugged into your power strip and then 2 hours in the wall.  I think you'll hear the difference (unless your power cord is too small and also limiting).

PS  My PP10 measures load and my total system load is 200 watts.  I think about 180 of it is the ZMA.  Torii mk4 is probably about the same.

According to the Torus AVR 15, the Torii MKIV pulls ~1.4A or 170 watts. The large value fuse is for start up surge.

Running a thicker gauge cable on the amp does change the sound. Running a thicker cable on a ZROCK2 also changes the sound.

Here is a reading of total system current draw.

Voltage In:      111V
Voltage Out:      118V
Current Out:      3.3A

Without the 2 Plasmatrons on it pulls 2.4A

10A surge protector is more than enough.

Many power strips even pricy "audiophile" ones ruin the sound. Just need to try them.

Before I got the Torus I was running a PiAudio uberBUSS direct into the wall. I would unplug the system often. Once I got the Torus I feel much more comfortable leaving the system on and plugged in. Only unplugging when really bad storms roll through.

Glad to be of service.

I think the Furman has little effect on the sound if at all. As always needs to be said, YMMV.

Caveat: I'm not hypercritical of a system's sound reproduction like many. If it sounds good than I'm generally satisfied.
