EVS Music Purifiers - Amazed by how much improvement they make! Anyone else try them?

A few years ago I had Ric Schultz at EVS modify a VTV Class D amplifier for me.  As part of that mod I bought a pair of what he calls ‘Music Purifiers’.  Small black cylinders with + and -  wires to attach to binding posts of your speakers.  I put them on my Gallo Strada 2 speakers, but with the new amp and other streaming equipment I was adding at the time, I never did careful A/B listening tests to see if they improved my systems sound quality or not.

Fast forward to 2023, when I hooked my old VPI Scoutmaster back into my system for the first time in years.  I quickly fell in love again with the sound of well recorded records and set out to upgrade my analog gear.  Early this year I bought a Sutherland Little Loco phono stage, a Lyra MC cartridge and a Schiit Kara preamp to handle volume control.   The path I traveled to arrive at my current analog system involved many rounds of A/B testing to find what gear sounded best.  The new set of components is now more musically satisfying than my DAC or streamer and I’m spending more time each week listening to new records and old favorites.

One afternoon while fooling around with my speakers (with EVS Music Purifiers attached and Audience Au 24 SE speaker wires), I decided to
A/B test to see if the Purifiers improved the sound as EVS claimed.

So I played one of the tracks I’d been using frequently for my earlier A/B tests, to see if having the Purifiers attached improved the sound.   After I disconnected their positive leads from the speaker terminals, I played the title track from Joni Mitchell’s Court and Spark.  I could tell immediately that something special in the sound was missing.  I quickly reconnected the Purifiers positive lead on both speakers and cued the track again.   Playing the track with the Purifiers reattached restored all of the SQ characteristics I’d come to love in Joni Mitchell’s iconic song.

The 3-D feel of the sound stage space, greater detail and so much more involvement in the music were all back.  I was blown away to find how important these inexpensive Purifiers were to hearing all the sound quality my new components were capable of producing!   Additional A/B tests with other tracks I love and know inside out confirmed the first test.  My experience so far makes me suspect that the better a given systems sound quality, the easier it is to hear the improvement these Music Purifiers make.  Using the Music Purifiers gives me so much added musical enjoyment there is no going back.  Listening without them is not an option.

The results of my listening tests with the Purifiers has been so surprising to me I’d like to hear from others on Audiogon who have tried them.  I’m curious to learn if you have found them as important to enhancing your systems sound as I have in mine.  If you do like what they do in your system, I’d love to hear what aspects of musical quality they improve and how much.

Thanks for any feedback!  If there is interest, I can post some further details about the tracks I used, and what things I noticed as improvements in each test.

Interesting that you mention the FX of signal above 200KHz.  Some years ago, a long technical discussion (I have a physics/engineering background) with the designer of Audioquest's sophisticated Niagara power conditioners convinced me that noise in that region could indeed spill over, directly or indirectly, into the audible range.  In fact, one goal of the Niagara design was to mitigate the effect of such noise.  Regardless of the theory behind the product, my own Niagara setup profoundly improved the sonics of my system, so those guys may have been onto something.

My question for you is: Do you see much value in adding Purifiers to a system that has already been configured to reject noise above 200KHz?  If so, given your return policy, I would be strongly tempted to make a purchase.

By the way, you weren't kidding about BitDefender.  After jumping through multiple BD hoops, I was finally allowed onto your site -- only to be confronted with a 404 Error.  There seems to be no way to get there.  It's possible that all you need to do is convert to to https and make sure your certificate is current.

I just sent payment for a pair of these. Going to give them a try on a set of high efficiency horns

I sent Ric an email about getting a pair of these, I have a feeling he is probably swamped with requests, so it may be a minute or 2 before he has a chance to reply.

The zobels inside some transistor amps are very similar to what I use.  By limiting the highs right at the output, the amp will "behave" better and be more stable. Having another filter at the end of the speaker wire filters the noise that the speaker wire is picking up and further cleans up any noise coming out of the amp.  Many transistor amps do not have these filters....and very few tube amps have them.

We CANNOT get enough PURE noise filtering.  It does not matter if your are using an inverter (off the grid) and a modded Puritan line filter and a separate ground rod and ground filters and star grounding and and and and.....My friend with his super modded Apogee speakers has all that.....but when he puts the Music Purifiers and Ground Enhancers directly on his speakers.....the sound is way better. 

Noise is distortion....distortion is noise.  This is the game we play......reduce the noise and what you are left with is MUSIC.....and the lower the noise.....the higher the goosebumps.

Yes, I am swamped.  I was already doing some other work for another company that needed to be finished.....and then this happened (me happy!).......and so......anyone ordering right now is looking at a 2-3 week wait.  I will email tomorrow (Sat.) morning all those who ordered already (and all those who will order after this moment) and try to give an approximate ship date.  If you wait to order....the wait time may extend.  Some people have been waiting for their Caladan speakers since Nov....and they paid over $3000 in advance.  This is a lot more palatable.  It will be worth the wait.
