Passive all the time. I've heard many transformer based conditioners and every time I've heard a reduction in dynamics. Others claim this isn't the case but listen for yourself.
WHICH POWER CONDITIONER IS BETTER PASSIVE OR ACTIVE WITH ISOLATION TRANSFORMERS
Looking to purchase a Power Conditioner to reduce the noise floor in my system as well as to protect my system from electric spikes. The two types of conditioners seem to be as follows:
- Passive conditioners such as an Audience AR-12 T4 which claims that passive conditioning with the use of chips is the way to go because their filtering is better accomplished without the use of isolation transformers. The proponents of passive seem to claim that the use of isolation transformers adds noise to the components in the chain.
- Active or non passive-An example would be the Niagra 3000, 5000 &7000 by Audioquest which all use Isolation transformers to accomplish the filtering. Most of the conditioners I see advertised seem to accomplish filtering with the use of isolation transformers.
- My question is what type is better and why? Any recommendations would be appreciated. My budget is $4000-$5000.00, would consider used, a/k/a pre-owned.
- Thank you for your input.

I'm glad this came up. I've always been in the camp that passive conditioning is the way to go, just filtering out the noise on the line. Every time I got new equipment, it always sounded better on my Niagara 1200 passive conditioner so when I got my Technics SU-G700M2 I used it that way for some years now, unit yesterday. It was just out of boredom from going through the last stages of weird cold (I'm on the 22nd day but feeling much better) that I decided to try out my integrated straight into the wall AC with everything else plugged into the Niagara. It was some kind of audio epiphany. More airy, clearer, tighter and defined with better frequency extension and increase in soundstage with absolutely no downsides. My Marantz Reference PM15S2 integrated was no slouch but still benefited from the Niagara. Whoever designed the power supply in the Technics should be given a raise. I can't believe the sound I'm getting from a $3,000 integrated. Suffice to say, it largely depends on the gear you're using as all power supplies are not made the same. I live in an old apartment with old wiring that had noise on the lines that went away when using the Marantz on the Niagara but hindered the performance of the Technics on the Niagara, so you'll need to see about getting a loaner and trying it out with the gear you have. Good luck. All the best,

@nonoise This is not the first instance Ive heard of the Niagra limiting current to an amp. And I fully agree it depends on the gear. |
