Telos Mini Quantum Resonator (MQR) & Puron Filter together

So, I have been a big proponent of the Puron Filters, they have been an awesome addition to my system. I now have a total of 10 of them plugged into my 3 different dedicated lines. Highly recommended!

Recently, I have tried the new Telos Mini Quantum Resonator (MQR). It is close to the physical size of the Puron Filter and also just plugs into the wall, but it has a different look. Kinda nice looking unit. I now have purchased 2 of them.

I’ll cut to the sound quality comparison. While the Puron expands the soundstage the Telos MQR deepens the image. It adds a heft to the music. More meat on the bones as they say. But too many Telos’s (MQR) though and the soundstage gets hardened. Whereas additional Puron’s is a good thing.

Plugging the Telos (MQR as the Puron) into my Niagara power conditioners is still not a good thing. They benefit the most being plugged into the wall outlet that the conditioners are plugged into.

Now a surprising location for the Telos (MQR) was into the power strip in another room that powers my computer equipment. i.e., Modem, EtherRegen, After Dark Clock and power supply.  At this location, my streaming from Qobuz improved in overall sound quality. I’m thinking because in this power strip there are more digital nasties that this device goes after.

So, both units together do provide an added synergy. It is hard to use one without the other. I now have one Telos (MQR) in my main system dedicated circuit and another with my computer equipment.



The Ansuz Sparkz TC3 and Nordost QWave are very different. Think of Wave closer to what you already know about Nordost. The Ansuz is mostly about bass enrichment/enhancement. And I find them to be very effective on other power lines to kill noise. 

Btw, there are two plugs I have tried that I have ruled out;
- Furutech Clear Line - seems to be good initially, but when you add a lot of other good products I found them to become a bottleneck.

- Chord power array - far to strong and negative impact on dynamics

I have just tried a new SR UEF AC plug, it seems rather good, but don't have enough experience with it yet.

I use iFi iPowerX power supply on my Add Powr Symphony Pros. What do you use?

I did not try the ncf plug, but with earlier use of the ncf iec outlet in proximity to power cables, this was when it was released many years before the plug was released.


It can easily soften and overly smooth the sound.


I use hynes power supplies for network gear, also mutec mc3+ so the symphonys, rr-77s, SR FEQand symphony's tap on these existing supplies, otherwise it would not make sense cost wise to utilise them just for the symphonies and tweeks.

Did look at the SR ac plug, but no description of what it is pilut me off as there are no trials outside the U.S.

Could it be some uef material on the lines of the ncf plug?



@cappuccino - Thanks for your response. So, the location of these items near the appliances lower the perceived noise floor of the audio? An acoustic measurement with a sound level meter will confirm. Or do they filter noise? Shakti stones do absorb high frequency emi noise. The other devices I surmise are providing harmonic resonance.


"Somehow, the QX2/Qx4 has different effect although much the same as the Symphony’s. It is either the thick housing or the algorythm is just different, more heft and dynamics." 

I can verify that your perception is correct.
