This type of device was first sold by Enacom back in the 90s (no longer available).  In the early 2000s Walker Audio created his High Definition Links.....and were made until Lloyd's death....they sold for $725....(they are no longer available). Merlin sold this kind of filter with his speakers.....(and these are also no longer available).  Stein Music (Speaker Match Plus and Speaker Match Signature.....$690 and $1750) are the only products using this kind of technology that is still being sold.    Please search and read the reviews of these kind of filters......mostly raves. 

The ones I am selling do exactly what the reviews state.of all the above.....that is, to make the sound more musical and more detailed.  You hear more separation of instruments, more hall sound, more air, lowering of noise and lowering of edginess and distortion.   You hear more micro details....string resonances.....lips smacking.....more of the wood sound.  This is not subtle....you have not heard your system till you have filtered the noise coming down your speaker wires.  Even at low volumes you enjoy the music more......just more real.  I spent a couple of months finding just the right values and parts.  The Music Purifiers are entirely hand made and are very time consuming to make.....very tweaky stuff is inside them.

It does not matter whether your system is $1000, $10,000, $100,000 or whatever.....or whatever new thing you have just added to your system.....when you put these $125 things on your speaker you will drop your jaw......you will not want to take them off.

Your speaker wires act as an antenna.  They pick up rf and then that rf rides on the signal and then you get to hear that noise through the speaker......The Music Purifier suppresses this rf so you hear much clearer sound.  These filters operate above 200K......they have nothing to do with the impedance of the speaker....they are universal.....they will work on every type of speaker.  They do not alter the impedance of the speaker.  They will not harm any speaker....in fact, some amplfiers have similar filters built in to make them more stable.  The devices I sell sound fantastic immediately......These don't need 200 hours of burn in to sound great. 

The EVS Music Purifiers are $125 for the pair .   If you buy more than one pair then the price of each additional pair is $100 ......Ground Enhancers are free with every pair....Yipee!  Sold with 30 day unconditional money back guarantee.  Shipping is $10.00 in the US for any amount of them. Shipping to Canada is $33 for priority mail or $17 for air mail......most all other countries are $47 for priority mail and $30 for air mail.  If you are overseas and return them then I will refund the price of the units plus $10 only (the shipping cost in the US).   

You would want two pairs if you are bi-wiring or bi-amping, I have not tried these on subwoofers yet but someone will I and will report on that possibility.

The Music Purifiers uses 18 gauge cryoed OFC wire with foam Teflon insulation that the ends are bent into a hook and tinned.....you can mount them directly on any binding post. 

We are taking orders now.   There is no direct order page.  You can either paypal me the money ($135 for one pair or $235 for two pair, etc....more if overseas...see above) using my regular email address as my paypal address; ( ricevs42@gmail.com )   or, I can send you a paypal invoice if you send me your paypal address.  You will love, love, love these things.  If you email me the money directly using Paypal then please send me a personal email stating that you just ordered.  I can also take Visa and Mastercard but you must call me to give me the credit card info.

For you tweakier users;......If you mount the Music Purifiers between your spade lug on your speaker wire and the connector you will get a mellower sound.  If you mount the Music Purifier on the outside of the spade you will get a slightly brighter sound.

A very few speakers have banana jacks only (Magnepan and GR Research are two).  You can try pulling out your banana plug just far enough to put on the Music Purifiers and push hard on the banana plug to secure.

Hi Ric,
    Wow, much more dramatic improvement in stereo. Really incredible improvement in detail, depth of sound stage, tone, musicality and virtually every parameter. I liked my system before, but the improvement with the rf filters is not subtle. I'm at a loss to find anything negative. I wonder if it will add anything to put additional rf filters on the 3 pairs of speaker terminals where the external x-overs connect? Do you think it will add further improvements? Is there such a thing as too many rf filters? 

Thanks so much for these awesome tweaks. I'm a believer.
Randy

Randy has Nola Baby Grand Reference Gold speakers with the external crossovers.... He bought 2 pair and tried one and a half pair on the input of one of the speakers in mono.....he said it sounded much better than the other non Purified speaker.....now he tried them on the input of the crossover (bi-wired) so he could listen in stereo and the below is the result.  Pics below:

This is how he listened at first......just on one channel

Now he put both pairs on the jacks on the bottom of the pic (not yet mounted)

Here they are mounted on Gallo Strata 2 speakers.  You can see a Gallo 3.5 in the backround.  Mapleshade stand and speaker wire.

Hello Ric, I’ve done a preliminary listen, yes, the presentation is clearly more articulate, more detailed, with greater ease.

Jean-Francois using Bastanis Matterhorn MK II speakers wrote,

The purifiers you sent are more natural, clearly open in "space" and bass is really improved , reaching lower and in a most natural way that is a pleasure to hear.
Ric,

    The addition of the RF attenuators works great on both of the systems which sound clean at all hours now and not just late at night! Also getting more "real" sounding music!

John
Ric, just wanted to let you know the purifiers are a hit! Them and the LSA GaN 350 have brought my system to a whole new level of enjoyment.

This person has the Cube Nenuphar mini speakers:

I have really been  enjoying the Music Purifier. I don't want to be without it now. 
 
After I put the Music Purifier on the speakers (Cube Nenuphar Mini) I tried the Ground Enhancers with together with them... on the speaker terminals... and I felt that I did not really hear any improvement. 

They did improve the sound when I used them by themselves, but in conjunction with the MPs, no improvement... to my ears, anyway.  So I haven't been using them... until 2 days ago. 
That is when I decided to try them on the negative outputs of my Enleum AMP 23R and in this configuration, I really did hear improvement right away. 
Really nice. 
What I am especially noticing is real tonal density... like real instruments... and tighter more musical bass. And the soundstage also seems wider. I am really glad I got them. 

I have in the past tried both levels of the Walker HDL and didnt like them. Made a few of my own switching out different values along the way but gave up. These have no negatives that I can detect........only positives. Cleaner, more solid image and better low end. Yes better low end. I did notice a change at about 5 hrs use but nothing since. Well done!!!!!

Ric,
I received it yesterday morning and it is worth every cent.  I
immediately heard the improvement in clarity.
Thank you,

I connected these today and I gotta tell you the improvement was not subtle. They immediately smoothed out the highs and increased the clarity. In my opinion pretty impressive. Do you happen to have another pair for sale? Thanks, Reynold
Way more pics coming showing them mounted on speakers, etc.
Installed on Spatial Speakers.
Ric,
Got the Music Purifiers today.
After installing them onto my Triangle Borea BR03 speakers (along with the Ground Enhancers—thanks!), I immediately noticed a [much] greater sense of air/dimensionality/space, better focus, improved detail and even enhanced tonal correctness/specificity.  Everything just sounds more refined and nuanced.
These are NOT going back!  : )
Thank you so much!

Deo gratias!
Patrick

Hi Ric - Just wanted to let you know- I installed the Prufiers last night, and was gobsmacked at the change in the sound from my system----Everything seemed clearer- instruments took a firmer distinct location in the image, low level sounds - trail of a cymbol, etc. had a depth I had not heard before, overall imaging was much more three dimensional and substantially larger and the deeper than before.

Basically, t was like a smearing of the sound was removed and I could hear much more of the music.

I am amazed at the improvement.

Thank you,
Michael

Hi Ric,

Thank you so much for getting these to me.  I was hoping for audible improvements (yes skeptical), but that was not the case.  It was dramatic. I can hear better dimensionality, and a more transparent presentation.  I thought that may just be me wanting to hear a difference, but went immediately to my second system (Akitika w/DQ 10 speakers) and then third (Primaluna w/Wharfedale speakers) stereo systems to make comparisons.  The change made the 2nd & 3rd system sound flat by comparison.  Again, thank you for a reasonably priced tweak and will recommend it to audio enthusiast friends & family.

Hey Ric, I just wanted to send you a quick note to let you know I got the purifiers today and got them hooked up to my Sopra 2's.  All I can say is WOW!  I started off listening to the Wallflowers 6th avenue heartache before I hooked them up then after, the difference is staggering to say the least, I can't get over the fact that this is the least expensive audio tweak I have ever done with what results as the biggest improvement in the sound of my system, these things are blowing my mind right now.  I am hearing background vocals that I have never heard until now.  I started out with them hooded up on the outside of the spade connectors on the speakers, I will let them go like this for a couple weeks then change them around so they are inside the spade connectors to find which I like best.  For now I can't thank you enough for this great product/tweak, I am in heaven!
