Hello,I would like to get impressions from people who own the Exodus JR Filter (Multi-outlet)... I'm aware it's an implementation of a diy design by Jon Risch, but I would like to know how Diycable's commercial version fared in their system. BTW, is it okay to use in 240VAC/60Hz lines? I hope the X-rated caps have high enough VAC ratings. I'd like to try it in my low powered stereo Class A tube amp too, I hope it doesn't kill dynamics and HF response. Thanks for the feedback.
Regards,
fred

Hi,
U r in the place where i was few months ago. Like u, i had heard a lot about the JR filter & finally decided to go in for it. SO i did & as i stay in India i had to purchase it online from diycable.com.
Over the past years i hv done many tweaks & diy's ( more than anyone could ever imagine). Each recipe by Jon Risch is a masterpiece. The guy knows what he says. He has terrific knowledge both in electronics & in the audiophile world.
But the JR filter which diycable makes, is the 1st piece of try, that DID NOT show any improvements. I was so annoyed that i just cannot explain. I certainly cannot doubt the recipe of Jon Risch cos it would be foolishness to even think that way. Im a very big fan of Jon. According to his recipe of room treatment, i have made 36 basstraps as a perimeter control in my room ( Scematic by Peter Moncreiff). Jon's basstrap recipe is beyond belief. The traps change the way you look at music. Even the belden recipe for the interconnect (both straight & twisted pair ) is awesome. In short every thing that Jon says can be blindly implemented.
May be it was my bad luck or may be the lack of technical expertise from diycable.com, that the JR filter they sent to me, awefully failed.
> But the JR filter which diycable makes, is the 1st piece of try, that DID NOT show any improvements. <Hi,
Thanks for the comments. If you did not hear any improvement/changes then I hope it also did not degrade the sound quality of your system. Could you confirm that? I understand that it is not an isolating device (iso trannie), but did it also cancel out switching transients from room lighting switches and other household electrical devices? Thank you.
Best,
fred
Hi,
As i said earlier, i have implemented all tweaks possible in my setup & all of them gave me some sort of 'plus' or the other. But this filter from diycable just sits like a fool in the line-up. I removed it some months ago & am using the system without any filter & it sounds just as neutral. Please be adviced that the bass in the JR filter made by diycable is on the heavier side. The bass in ur system will be more neutral & flat WITHOUT the filter. If u dont believe me, u can definitely give it a try & see for urself. Im not saying that its screwing up the sound or anything....wat im trying to say is that "why pay for sumthing that does nothing". I hope that answers ur question
Please realize that everyone has a different amount of RFI and EMI riding on their AC power lines, if you have very little of both, then adding an AC filter of any kind will likely not do much good.On the other hand, a great many people in the US have a significant amount of RFI/EMI on the power lines, with no small amount coming from their own appliances inside the house! Computers, refrigerators, fans, microwave ovens, TV's, VCR's etc. ALL tend to throw hash and/or RFI back onto the line, in these instances, use of an AC line filter designed to do some filtering, without mucking up the audio components sound, is going to be a huge help in achieving a quieter more listenable playback experience.
Out of maybe two dozen locations in the US where I was able to become familiar with the sound of a pretty decent playback sytem, insertion of a JMR AC Line Filter (and SS in most cases) caused about 20 of them to improve sonically, and of those twenty, about half were quite significant. Of the four that did not show noticable gains in playback enjoyment, on three the filter did no significant harm, and DID provide the Surge Suppression and Spike protection without a downside, which is not a trivial thing to achieve. One of those four was a fairly large (200W plus) power amp, and this system did suffer some loss of dynamics and punch, but it was barely noticable, and ONLY by direct comparison.
In general, only those with relatively large and power hungry amps will experience a definite downside using one of my filters.
Finally, unless DIYcable has recently changed the 'recipe' on the filter kits it sells, then they work as intended, and as effectively as any good parts layout should.
Where folks have had the most problems and trouble, has been when they deviate from the recomended components, usually with the mistaken idea that the specific parts used just don't matter, usually after having been told this by a salesperson at the parts store, or some well-meaning, but inexperienced tech freind of theirs.

Jon,
Watever u say, i consider as golden words....There is absolutely no doubt about it. As i mentioned in this post earlier, i am a VERY BIG FAN of ur's. I have implemented all of ur recipes & with fabulous results. The only one i dint want to try myself was the JR line filter, so i intended to buy it online from diycable. But to my surprise, it dint perform as expected ( or should i say, it dint perform at all). I live in India, & here the power is 20 times more polluted than in the U.S. I certainly have no doubts on ur recipe, but i am not sure wat diycable has used. Thanx for the explanation, i really appreciate.
I'm a JR fan too, though everything anyone says will inevitably not be perfect for everyone else!I haven't used Jon's main power filter scheme as yet, but I have implementd his SQ&D Isolation Transformer for my digital front end. That works like a charm! It's a DIY, by the way, and very very easy to make for under $50 in parts off the shelf.
No expert here, but from what I've read, tried and heard, power filtering is a hit or miss thing. Many power filters that directly impact your analog amps have dynamic limiting problems, while digital filtering appears to be more commonly successful. The digital end is loaded with RFI, so that's what the filtering is helping to control; perhaps the RFI in analog isn't as easily controlled.
However, I have been fortunate to have corresponded with Al Sekela on this board, and Al has a great grasp of RFI controlling mechanisms. With his guidance, I've done considerable power cleaning on my analog amps (not heavy tubes, BTW) with simple cap arrays and magnets. It works, is damn cheap, and sounds great! So I suggest you ask his advice on this stuff.
