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.



Thanks, cappuccino for that additional information. I think you would be surprised if you add a couple Puron’s to your system, they work very well together.


@ozzy I guess they are good. I live in Europe, and haven´t found any sign of dealer here and having Puron available with Schuko. Maybe you know?

I've been using a Telos Mini-Q for several months and am very happy with the improvement in sound quality. My results mirror other's findings as to the nature of improvements. I found the Telos to be more to my liking than using an EU4 plug. I'm using the Telos in the second outlet feeding my Shunyata conditioner and a High Fidelity Cable Helix+ plug in each of the Shunyata outlets powering my Preamp (BHK pre or Luxman C700u) and amp (Luxman M700u.)

My 2nd Telos Mini-Q while not giving me the big improvement the 1st one did is still worth the dollars IMO. I'll try relocating it to near my router and see what that does.


I guess I’m the only one that has had no luck with the Puron filters. I had them in my main system 4x over the last few months. The last time they were in my main system for more than a week. I finally pulled them out and hoped my system would return back to normal, which it did. I guess my front end equipment was not compatible with the filters.
I’m not complaining just very disappointed that I didn’t get the same great results others have posted. They are now plugged into my second system. They are on the circuit that my TV and 2 channel system is on. They sound ok on my second system.
