I am planning to connect all the power cables to this :
Sereno MAX Balanced Isolator & Power conditioner
Balanced Isolation Transformer
>> Rated power : 3500VA balanced Isolator
>> Operating voltage : 200-250VAC manual selectable
>> Linear Noise Attenuation ratio
: -202 dB at 1MHz (Digital filter : Optional) for media player
: -180 dB at 1MHz (Digital filter : Optional) for any AVR
: -43 dB at 1MHz (Analogue filter : Optional) for power amplifier
: 50A DC blocking for any equipment
>> Rated output power
: 3500VA total non isolated power
: 3500VA total isolated power
>> Maximum surge energy : Total 10,200 Joules
>> 50A DC filter and Libero HD and Libero SC modules
>> Balanced/Floated switch
>> AC Line status indicator phase, ground, abnormal voltage (Optional)
>> American Denki receptacle
>> Hospital grade US connectors with Audyn exterior aluminum housing
>> 7-Segment output voltage indicator
What I Plan to do is to leave the power buttons on all cats and Sumb in the " on " position.
I will use the power button from this transformer to turn on everything.
Is this a good idea? is there any issue to be worried?

Rated @3500VA, that's some significant reserves....but....the primary caveat with any iso unit is a nice low impedance, high current capability,...without any current limiting effects.
So many questions....
What exactly will be powered by this unit? Three Cat12's and one Submersive? What about the remainder of your low level gear; source player, pre pro, etc.?
Is the unit fed with two separate hot circuits? It appears as if there's 2 captive cord feeds.
Why feed the SubM thru the Iso unit? Convenience? I'd be hesitant to recommend any high powered subwoofer amplification to be fed via a potential choke-point. However, this piece may be quite robust with no current limiting whatsoever. I'd think the Cat12's could be fed thru this thing with no issues at all, as their current draw would be peaky, but however nominally low in level,...thus the iso unit wouldn't likely be restrictive with the Cat12's.
Good luck
Other's thoughts?

Personally I'm NOT a fan nor advocate of balanced power, but it can work just fine.
I much prefer a product like Torus Power, which includes series mode protection from power surges along with big isolation transformers. You can also purchase the series mode protection from Surge-X who were the first to develop the technology. I have recently seen a few new power blocks which are more suitable in form factor and capacity for home theater.
So far as capacity, you should be just fine with 3500VA on the Catalysts and SubMersives. If that uses a single large transformer, I wouldn't be too concerned about any loading. If it is separate transformers, then you may or may not want to put the subwoofers on them. For the most part I don't see the real world usage to be any issue here.

FOH and Mark
I will be using this only for 3Cats 12C and 2 1000w SUBms (will upgrade to 2400 ) in the future.
This unit can be custom to 7000 VA. You are correct about the unit needs 2 hot circuits : one for non-isolated and another one for isolated.
There are at least 2 non-isolated inputs for this unit. But I believe It can be made to any demand.
So FOH, My guess is that I should be connect all the power cords to non- isolated inputs , correct?
What is the best input for active speaker like Cats ( Isolated or non-isolated) ?
Mark, thank you for sharing your thought.
I'll be looking into the products you mentioned.
Another reason that I will be using this unit is that It has electrical protection. I do not want to risk my equipment ( Cats and Subm) with surge problems. I hope the product I mentioned is good enough for this purpose.
