Does an Audioquest Niagra 1200 limit amplifier dynamics?


Hi, I have a Belles 150A Reference amp driving Vandersteen 2E sig speakers, which I don't play loud at all.  I currently have everything else plugged into a Shunyata Hydra 6, but felt it limited the amp's dynamics, so it's plugged directly into the dedicated line outlet.  Would an Audioquest Niagra 1200 do better?

Not all power "conditioners" are created equal nor are any two home/power delivery situations identical so there is no universal answer to your question. It also depends on the amp (class A or A/B)

Exactly! And explains vastly different outcomes being reported here. It depends.

I agree with @carlsbad regarding conditioners (at least the 1200) reduces the rapid current changes which limits the amp. I unplugged my Atoll IN300 from the 1200 and plugged it directly to the wall and my amp came alive again. I’m not saying the 1200 is not a nice conditioner, it’s just not for me. By the way, I have one if anyone wants to buy it. 🤪

I can’t speak to the Niagara 1200 directly as I have a Niagara 7000. The way my dedicated power circuit is run, I can either power my ARC Ref75SE from the high current outlets of the N7K or the from the same duplex wall outlet as the N7K. There are no downsides and significant upsides of powering the amp from the Niagara 7000. Noise floor decreases and dynamics improve, whether due to the improved noise floor or because the dynamics actually improve or both. There is absolutely no compromise powering the amp from the Niagara 7000’s high current outlets. While not a direct answer, hopefully this data point is useful in some way.

Didn't read any above posts. From a pure understanding of physics, No. No need to impede voltage or amperage = power to a power amp ever!  Filter your source. Not your power. Your source gets amplified, which amplifies the noise!  All good power amps have noise reduction by design. In fact, your power amp was designed to function on the typical impedance of your ac mains. How can another circuit in from of that improve your AC feed. ANY other circuit in front of your amp will increase impedance. It is impossible that it can reduce impedance based on physics, Come on Man, really? You ask this question?   Don't be daft my friend. I'm not British but I watch British TV.   Those who place a power supply "conditioner" in front of their power amps likely a. never studied physics in college, b. never passed physics in college or c. never went to college or cared to understand physics. Sorry if this offends anyone, but this is my truth. Peace. 

markiew - where you indicate…


The 1200 is OK, but as above, the Puritan PSM156 is much better, its certainly better than the Niagara 3000

 

what benefit from the PSM156 did you get over the AQ3000?
