One of those products/tweaks that works ill bet...head shaking mandatory?
I was a skeptic especially afterhav8ng the synergistic purifiers ,but I far totally wrong these are night and day better, the clean up the signal through the mundoff ultra resistors then to the top of class Duelund capacitors which are much better
then in most speakers for sure, unless you have tried these new Products don’t
give a opinion it’s just speaking out of ignorance ,myself and 2 friends tried these That have the same 4 ohm speaker as myself they are. Built per speaker.
This is a well known zobel network, been around for many years and most x-over builders have probably tried a version or 2 when load is of and you need to even out impedance over the frequency band . How much it influences the sound have probably more to do with the amplifier not having a hard time driving the speakers. A well built speaker with a well built network and good drivers have no need for this " purification "
All the best
I would like to share my experience with the purifiers that I purchased from Audioman58. I have been in this hobby for some time and over the years have auditioned many speakers, amplifiers, tweaks etc. This experience has helped me sort out the many of the snake oil tweaks from the real deal. That said, my experience with the purifiers is that they performed exactly as described by Audioman58. In regard to the post by iseland, while I agree that high quality crossover components will provide many of the benefits that the purifiers provide, let me say that I have a Hegel H390 amplifier with a 4000 damping factor providing 2x250w into 8 Ohm and 400w into 4 Ohm. I say that because this amp is cable of driving and more importantly controlling drivers on the most difficult speakers. When I added the purifiers, they provided their value in short order; exactly as described. They will improve SQ even if you have high quality crossover components in your speakers. BTW many high priced speakers on the market use many sub par components in their crossovers. Happy user!
I am the builder , I will answer several question, yes these will work even if amplified ,for the amplified section is fed the audio signal then goes to the preamplifier -internal Xover ,these Filter which = cleans the audio band of noise ,not the same as a RC filtering in a Xover ,for one there is much times spent using various size capacitors for the the filtering ,and your speakers ohms, impedance determine which resistors I use ,which BTW these parts are night and day better then then 95% of the Xover parts in most speakers including anything at $25 k for example.once these are runin at least 100 hours they then start to open up. And get better to 300 hours.
I checked with Golden Ear yesterday and they do not recommend using on my Triton Refs, saying it could possibly damage the internal amp and DSP. With that being said, although I would love to try it, I don’t gamble so I very reluctantly will pass. Unless of course someone with my speakers is using them successfully.
"Just ordered a set for my son in Texas will let you know what he thinks. BTW he is an audio engineer in Austin his wife is an EE".
Awesome! They should be able to hear the change immediately but will get much better after crossing that 150 hour mark and continue to improve past 300 hours.
I was considering a Loki Mini+ EQ but the positive change in clarity, smoothness and musicality these purifiers brought to my system and I have no desire for an EQ now.
Are purifiers beneficial on Magneplanar speakers, and has anyone tried this on MG20's? I have rebuilt/replaced the stock internal crossover components with Janzen silver and Audine copperfoil capacitors with Dueland 14 Ga air core copper foil inductors. There are Mundorf 0.01 MFD Silver foil bypass caps in parallel with the Janzen Caps. After a lengthy break in the speakers sound much improved. Will these purifiers help more?
I received my purifiers from Audioman58 last week. I thought I would try them out since my amps plug directly into the wall. I have dedicated circuits for my amps and the front end but the front end components are supplied power through a Niagara 5000 conditioner. My thinking was that some filtering on the amp/speaker side might be beneficial. I have 100 hours now on these purifiers that Audioman58 designed for my 4 Ohm Thiel CS6 speakers that I am using with Pass Labs mono amps.
After doing a 72 hour break in on my old HT receiver I put them into my stereo system and let them play for another 15 hours or so. They are still changing but I have made some conclusions. I hear a smoother sound. I don't necessarily hear a bigger soundstage but there is a bit more air to instruments. Af first the smoother sound seemed almost blah. But the next day the sound was better. Whatever these purifiers do, I found that I had to reposition my speakers. After two 1/4" speaker position adjustments the soundstage came back into focus and the clarity was back. The other notable difference is no more ear fatigue when listening at high volumes. All gone. I don't hear a change in the highs but I wonder if these filter out some high frequency energy that I don't necessarily here but still has an impact.
I wasn't sure at first but now these purifiers are growing on me.
I just priced out the parts used in Duelund/Mundorf Ultra Loudspeaker Purifiers from the Parts Connection website, and just the parts would actually cost more than entire assembled unit costs! Audioman58 must be sourcing the parts at a discount in order to make a profit.
Jury is still out on its effectiveness. I probably have about 40 hours on them and it has been recommended to give them several hundred hours of break in.
