Alpha Labs - Do Parallel Filters actually work?

We went in to the lab again. This time we are going to look at parallel filters. Yes: those 'magic plugs' that clean up power for our lovely hifi gear. Do they actually do something? Let's find out!

If you stop doing these tests due to A--holes you're letting them win. Please keep up the great work!

[@tf105db]

I agree. Please don't stop and keep on the good work!

[@TheAlphaAudio]

Thanks....

[@ericvanvianen2818]

Don’t let them get to you. Your efforts are highly appreciated. 😊

[@GregoryfromTrier]

Please continue! Your reviews are very interesting and much appreciated (especially this Alpha Labs series). Your channel is one of my favorite and very important to me to access to the audiophile nirvana... one day! 😊

[@stephenmeckley]

So grateful for all your videos! Keep up the fantastic work!

[@joes7874]

This is quickly becoming my favorite channel. Please keep up the good work

[@christopherkent6512]

Great job, thank you. Never thought that something a little larger than the plug could make any serious difference.

[@TheAlphaAudio]

Well... they work. 🙂

[@christopherkent6512]

@@TheAlphaAudio you are correct. However, I do not think they do as much as the purchaser believes they will. That’s why say “serious difference”. I do enjoy seeing you having fun, sort of stuff I like to do.

[@Bobbear1976]

Thanks for the videos, really appreciate all that you do👍🏻

[@georgecav]

On my little yt channels there is a setting where potentially disrespectful comments are filtered to you and you can get delete them. I would do that if I were in your shoes and I have done it on mine. Its so refreshing not having an influencer running a channel with sociopathic charm and engaging & convincing yet incorrect advice at times so I hope you keep it up.

[@TheAlphaAudio]

Thanks for the advice. I will check it out!

[@georgecav]

@@TheAlphaAudio when you upload your videos, from the 1st page on YT upload choose 'Show More' then scroll down to 'Comments and Ratings' and you can choose your settings. You can make that the template for all your future postings so you don't have to repeat it every time but I forget how I did that

[@phillipmorris9847]

Love all the alpha labs content ty ty

[@phantomplastics6582]

Great work again and highly appreciated! These questions come up again and again and the only way to know for sure is measurements.

[@TheAlphaAudio]

Indeed!

[@jasonc331]

Don't let the ASR folks get under your skin! More people trying things is how people can learn, good or bad.

[@raymcnamara7843]

Thankyou so much for what you are doing in the Test Lab. As a60+ year Audiophiliac, and retired Electronics Engineer who started his career in High End Audio Servicing, I am very envious of your Test Gear setup. I think that your "Feedback Issues" are generally (mostly) due to ignorance, mostly due to a lack of understanding of the "Scientific Method", and also how it is almost impossible to undertake such measurements as attempted on this channel. Just don't engage with those A--holes. You would loose too much valuable time in the Lab if you start interacting with those who give humanity a bad name... Thanks again...

[@TheAlphaAudio]

Thanks!

[@LuxAudio389]

This was really good. I really don't understand why these things matter so much when my audio equipment converts everything to DC, but it does make a difference. I have a parallel transformer and an isolation transformer and there is a favorable difference, except on hot days when the grid is loaded by air conditioners and etc.

[@berrydehaas4948]

Keep up the good works, azijn zeikers zijn er altijd

[@zeram01]

Don’t let the negative anonymous trolls bring you down. The informative content that you afford to us non-haters is always appreciated and makes the Internet worthwhile!

[@stoicar]

Best i see until now . Many thanks

[@adrianadrianp5305]

If you use larger caps on parallel filters you can go much lower with noise reduction, I have used 30uf value caps which are large, then cascade down to .01uf or less

[@NiclasMardfelt]

Great! Helped me a lot!

[@Paxmax]

Good test!

[@joshua43214]

Please keep it up. Ignore the ASR cultists, like all pseudo-science believers, they can only resort to trash talk when challenged.

[@AL-ye2fo]

Fantastic channel, thank you!

[@frankkahlweiss9696]

Hello please keep up the good work, just leave the complainers aside. I find your tests super interesting, because if I had the lab equipment you have, I would do the same tests. Please keep up the good work, greetings from France, Frank.

[@TheAlphaAudio]

Thank you Frank!

[@jmtennapel]

We have tested a lot of these parallel filters by ear in this livestream, from September 2022: kzbin.info/www/bejne/bqjPlJp8erGboKM

[@ulrichgorlich6292]

Keep going I like it a lot

[@dickvanderwal5005]

Super interessante video weer. Dank jullie wel. Wanneer komt er weer een live stream?

[@TheAlphaAudio]

24 september

[@topkho]

You’re the best channel please don’t listen to the negative comments 😮 😊

[@TheKent2288]

Thank you and please continue the excellent series. Ignore the haters as you can't please or change mind of everyone. Flat earthers case in point. How about testing of those Entreq earthing boxes (for fun)? Also really interesting about negative effect of SMPS plugged into another transformer. Something I will look to avoid now so thank-you very much for the education :)

[@TheAlphaAudio]

Thank you!

[@antcollins6594]

Have you done any measurements to see if there is any impact on the output of audio devices (amps/dacs etc) when these types of filters or mains conditioners are applied to their mains inputs?

[@TheAlphaAudio]

Yes. In the other Alpha Labs video. I measure at the speaker output of a Bryston amp.

[@vtkz]

Any chance to see more active monitor multitests (like Neumann KH150 vs Genelec 8331 vs PSI A21M vs Barefoot Footprint01 or similiar) ?

[@TheAlphaAudio]

Sure. But not sure when... :-)

[@adrielaan]

Lekker doorgaan Jaap. Het is geen wetenschap maar laat genoeg zien om te weten wat er speelt.

[@TheAlphaAudio]

Thanks!

1. It's a tough world out there, most of us fantasies about being in our privet tropical resort with no out side feedback if it not / unless it is positive and compliment Sadly, it is only a fantasy... 2. Modern times brought us consumer audio products that are well designed - some of them are even well manufactured - that have excellent inside the box power supply performance. So if your mesurmant's shows how poorly/good performed that box or the other (power sup noise issues for example) - fantastic! a true valuable information for the modern music listener homo sapiance. Dacs, pres, powers, integrated, processors that can be plugged to the wall outlet and preform with high Q&A over wide range of parameters - ARE out there on the free market and some of them even priced with respect for the customer and modern time market competition and brands flood/saturation. 3. Most of us - YT channels consumers - are not qualified/trained measurements and analysis engineers - it would be of the out most help if you will explain us your protocols, your tools the way you calibrate referance,scale/resolution Software setups/modes and most importantly: Why and how you interpreting the data and correlate it to audio signal quality improvmant/deterioration on the consumer= Listener EARS side. Whether it's in the known audible scale/psycoacustic acknowledged or on the theoretical / absolute / golden ears scale. 4. It's takes time and persistence to build a strong YT channel and "mostly positive" feedback comments community. especially when that channel is in crowded market. Be patience, keep it interesting and educational, demonstrate Consistancy of quality production, presentation and analysis and you will gain what you are aiming at. Be blessed, healthy, free, educated and prosper.

[@TheAlphaAudio]

Thank you.

[@MRPriveteyes]

Hello i would like your opinion on what filter should i use buy. looking for isotek titan for home theater hypex ncx500 11 channels all run using smps switch mode power supplys. Marantz av10 processor.

[@MRPriveteyes]

Like in shunyata review mentioned that for switch mode psu should be some kind of special filter))

[@sergeiu8101]

Hello! What could be the best option for power filtering in case of active speakers (D class) + pc setup? Is it reasonable at all?

[@TheAlphaAudio]

It completely depends on the resolution of the system. Pc power supplies are very dirty. So filtering that could definitely help.

[@Musiclover-cj1hn]

Compare with this commercial filters 👍

[@sc0or]

-60dB of noise plus -60dB (in the worse case) of PSRR of an amplifier -120dB which you won’t hear at all.
