Would one of these handle two evo amps and one evo dac, I would then use the other for my av preamp, a mch-k38 and my uhd player?
Yes, this is exactly how we envision customers would use Pure AC-4.

Please don't mix the noisy devices like settopbox or TV on the same Pure AC-4 with high end audio components.

I read the manual and it mentions surge protection, there are very little details. I assume the units will provide proper surge protection if I happen to not be home during a thunderstorm.

If I am home and there is a storm I always turn the breaker off to my equipment.

That's correct. It has a circuit breaker.

Hi everyone,

I have one nuprime ida-8 with klipsch heresy III. I have a terrible hiss/hum sound with no source connected, same at all levels. I've tested different conditionner and cables but no one works. Do you think the ac-4 can help me ?

Thank u.

No. If this happens with no source connected, it could be that the ida is turning into an 'antena' picking up frequencies.  The other option is that the wall inlet your are hooking your ida hasn't any ground, and the ground 'appears' when you connect a properly grounded rca cable.

Neither of these will be solved by the regulator.

At least I don't think so.

Have you tried with different wall sockets (for instance in a different room)?

The antena issue is harder, you would need to cover the ida with something metallic to see if the hum goes away.

If you touch the rca sleeves in this scenario, does the hiss hum change or goes away?

I've tried every wall inlet in my housse and at my parent's housse too with every other gear (phone,box,friidge,...) disconnnected , and the noise was still there.

In this scenario, you mean I should touch Rca sleeve?

I have touched the Rca with my finger in normal position and nothing change.

Try to use a AC adapter plug with no ground to see if the noise goes away.
Something like this:

wait, you said "I have a terrible hiss/hum sound with no source connected, same at all levels"..
so what happen when a source is connected? Then the noise disappeared?

I've already tried the plug with no ground with no success.

Same noise with my cdt-8 with coaxial connection.

klipsch heresy III is a 99 db sensitivity speaker, hmmm, are you listening very close, ie a few feet away?
You might be hearing the even order harmonic of IDA-8. 
You didn't say whether this is the first time you got the IDA-8 or speaker, did the noise develop after a while, or it is there from day one?
Try a different speaker to compare.
Regardless, you should create a help desk ticket and contact support to continue with the diagnostic.  This discussion is beneficial to other users but not under this topic, which is for AC-4 product.

My mch-k38 has a fairly high noise floor compared to my other amps, but I still have to put my ear right up to the speaker to hear it, and im hearing this with 90db speakers so I could only imagine what 99db speakers would make this noise sound like.

As rusty said have you tried this with other speakers?

The noise is the same from the beginning, I've heard it 15 feet away. I've tried a hegel H80 and absolutelly no noise with the heresy. I've sold my IDA-8 and ordered a brand new IDA-16 because the nuprime sound is what I like the most. I hope there will be no noise.

 Take a look at this link

My mch-k38 makes a  very slight whine/hum that none of my amplifies do so I hope the ida-16 works well for you.
