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 Purons may also be of similiar ilk or are derived from ceramic and quaritz crystals with interesting field properties whebn in contact with the AC line.

I don’t know bemused if I totally agree. I have used the Nordost products, and the Puron’s and Telos items are more effective and cheaper. However, as you mentioned they may be based on the same principle. Have you compared them?


I dont know about Telos technology, but what they do for both audio and video differ from Nordost according to my experience. And I have plenty of every Nordost QRT product, including the new QWave and QSine, and Telos over several years. Also comparing Telos to Add Powr (run by the man behind the Nordost QRT products), they are very different. But IMO they compliment each other very nice.

To others who experiment with one plug in the wall next to the outlet for your conditioner, why not add a power strip and add several and dfferent power plugs. If you have space and funds for it of course.

And, if you are not quite happy with a product in your stereo, before you sell it or return it, try it on your ac line for your refrigerator or freezer. I have found that reducing amount of noise going back to meter board from these devices helps a lot, even with dedicated ac lines for stereo.

Hi cappucino,

How are the QWave and QSine?


What effect do they have.

Have you tried the purons too?
