Furman Upgrade to Niagra

@audphile1 thank you, as always a wealth of helpful information!

I also ran a dedicated 20-amp 12/2 circuit for my system with upgraded outlets.

So, you think a power conditioner isn't necessary if that's the case?

It’s hard to say unless you try. I tried and liked my components direct to wall. I had puritan psm156 with both classic and ultimate power cables.
While there was what one can perceive as a very slight drop in noise floor, the restriction in dynamics and top end extension wasn’t something I was willing to live with. And that was with only dac and preamp plugged into the Puritan.
I now have a streamer as well, Aurender N200, and I have no issues with the system running without power conditioning. 
But like I said, you won’t know until you try. You might like it with the power conditioner in the chain. 

@erik_squires do you have a particular model or brand of power conditioner that you recommend Eric?

@navyachts, I have 2 dedicated 20-amp circuits for my audio system and both circuits are connected to  Shunyata Hydra 4 power conditioner.  Shunyata conditioners do NOT limit current, and it is advisable to plug your amp into them.  My system is extremely quiet, and the dynamics are off the wall.

OP:

I recommend SMP and LiFT as must-haves and the least expensive unit with that is the PST-8. Beyond that, the Elite 15 PF (or 20 PF) adds things like power factor correction and multiple separate power banks and switched outlets, which are great when used with a processor and extra amps. That’s what I use.

If you know you have unsteady power a unit with voltage regulation can also be considered but they are a significant extra charge as it requires a big heavy transformer. It will keep your AC voltage within a tight 7V range except in the worst of circumstances. I lived in a complex with 130 VAC (long story) and the regulator kept me between 118 and 122VAC.

Honestly if the PST-8 has the necessary outlets for you it’s an excellent choice for simple systems.
