SnubWay Noise Defender

Hmmm, would it be better to plug the Snubway into the free socket of my Core Power Technologies Deep=Core 1800, Equi=Core 1800 Mk3, or directly into the mains outlet that feeds the audio system? I could always experiment, of course, but it would be nice to have a recommended starting position.
 
Looks pretty, well built and using decent components. However, if your equipment has decent power supply and filtering, not likely to make any audible difference. IMHO.
You would think so. However, several reviewers have noted that they added this to their existing power line conditioners (some pretty expensive and impressive ones) and there was a reduction in noise. I am not sure why but perhaps it is blocking locally picked up SMPS EMI noise.
 
no thread for the mainstream? I see on the mainstream product page a screenshot says it was named the Puron 2 before.. is this an xrk designed successor to the Puron? I'm tempted to order it but I only want it if you designed it 🙂
 
Hi xr
Different paths to what appears to be the very same goal - the MainStream. And unusual for a company to offer two products with the same goal at the same price

So could you outline the differences in the effectiveness of the two. I’d think much more useful based on the data rather than listening.

Id guess it’d be more useful if you say something about frequencies. But you would know better than anyone(!)

I say frequencies: is there a frequency range where they are most effective? Because as best as I could tell from zooming in on one of the trace graphs - which is pretty limited, there is a little more benefit below maybe 200 Hz. But I wouldn’t say that with any confidence.

For use with: pretty sure it was the descriptions at VeraFi of the earlier MainStream model which talked a fair bit about the benefits on a turntable with MC cartridge. That would seem to make most sense for any device of this type. Is that correct?

For folks like me who have a TT with MC. Would the MainStream give more benefit than the new Snubway?
Id guess that nowadays more people use a network streamer. Which I also use. What would be more effective with that?

Are the two complementary ie one does X better and the other something else
 
Here's a snippet from the Positive Feedback Writers Choice Awards article (https://positive-feedback.com/audio-discourse/2024-positive-feedback-writers-choice-awards/) that may be helpful in delineating the two products:

"The Main Stream Master Class Dynamic Parallel AC Line Conditioner and SnubWay Noise Defender are a new pair of designed "from-the-ground-up" AC power conditioners developed by Vera-Fi Audio. Each device employs specialized filters that have been specifically tailored to address troublesome aspects of AC mains noise, and Vera-Fi's Mark Schifter clearly didn't want to go with a "one size fits all" type device to accomplish his goals. SnubWay is an advanced parallel mains noise filter, or "snubber;" its multiple discrete LRC filters are tuned to absorb AC mains noise in the 10kHz to 2MHz frequency range created by switch mode power supplies and other sources. However, its greatest range of effectiveness is in the problematic 400kHz-600kHz range, where most of the noise it's designed to eliminate resides; you can read my review of SnubWay HERE. Main Stream's effectiveness is focused on the frequency range from 10kHz to 20kHz, but it's particularly potent in and around the critical 20kHz region, where hum, hiss, and hash tend to be most prominent. Main Stream directly takes aim at frequencies where so much of the other equipment in your home creates noise and pollutes the AC power stream—the same stream that also provides current to your audio and A/V systems.

Main Stream and SnubWay are individually focused on eliminating noise from specific, problematic frequency regions, but they've also been designed to overlap their coverage, working in tandem to provide a complete solution for the elimination of AC mains noise. They also offer a staggeringly good one-two punch when used in combination, and are what I now call the dynamic duo. And they're priced such that everyone can afford them and benefit from the improvements they'll bring to your system. Even though I have Audioquest Niagara power conditioning in both listening rooms here in South Carolina, I was shocked by the level of improvement with both devices brought to my dual systems. Main Stream and Snub Way come very highly recommended!"

Since my BPT power conditioner has 6 separate secondary windings, each shielded from the other, I would think that the most effective way to connect your device would be at the AC power wall plug. That way, the primary winding of the balanced AC transformer is affected, thereby affecting al circuits/windings downstream.
 
I'm now fully protected from noise gremlins by the snubway and mainstream! my pi audio group mini buss is fully populated.. the super thick power cord goes to my antek balanced isolation transformer where all my audio gear is plugged in to.
