Nordost QKore isn't cheap but they seem to have thought things through...

They said they opened up a few  competitor products and found organic material which they said degraded over time.. so they went to engineer a compound that would do the same grounding effect but wouldn't degrade with time. A customer said he preferred the 2 box QKore 1+QKore 3 vs 1 box QKore 6.

How do the Entreqs and similar stack up vs the active Telos GNR, and vs the piece meal Acoustic Revive RGC-24 ground conditioner?

Qkore1+ qkore3 gives a more solid image than qkore6

The ground cable will influence the sound quite a bit. Power cord in the case of the active telos gnr

I have used all 3 before. I retained the rgc and entreq in my system. Telos does not work on my system. I was told that it is not compatible with my torus avr power conditioner.

Probably an open-ended question, but how does the AR RGC compare to the Entreq?

Was there any explanation (from Telos, perhaps) as to why a grounding device would not work with an isolation transformer?

I used both rgc and entreq together and found them synergistic. The rgc lowered the noise floor as did the entreq. The telos made my music dead sounding with or without the other grounding devices. Highs lost their sparkle. I read that others found it to have worked and directed the question to our local distributor as well as to xaudio. In any case, I returned the device and did not buy it. I bought a second entreq tellus 2 box instead.

Is the Torus a balanced transformer? I couldn’t use the GNR with my plixir because of that reason.

Thanks, murphys33. Always wondered about their impact on a high end balanced AC conditioner.  Guess I would have to do a home demo at some stage.

Straying a bit OT, if you had to chose between the RGC, Entreq and the Stein, which would provide the most audible impact for the lowest investment?

I have limited success using RGC24 with  RR77 in a very hostile RF environment close to our national transmitters. I cannot totally keep the noise at bay. But staging, imaging and layering improved with their use. Yet to try other grounding tweaks as space is at a premium

I was told that the telos does not work with balanced transformer type of power conditioners. My trial does confirm that as well. I think the 3 products does different things. It has been a long time since I did audition for individual impact and  I would be hard pressed to isolate their individual effects. Their different price points also make it hard to qualify bang for buck comparison. Sorry cannot help there. I would say that the stein would be a main stay and I would choose either rgc or entreq to pair with stein. If I have smaller budget, maybe rgc. If I have a bigger budget, I would start with entreq

Eh?, both RGC and Entreq?? Kind defeats the purpose of having a single common ground when you have both in-use...
