The Shunyata products are completely passive, so I don't see how they could ever "fail" and reduce the current being provided to the DSP speakers. I suppose active conditioners like the Audioquest or PS Audio units could, so maybe they should be avoided.

Since my original post, I've replaced the Denali on my speakers with another Triton V3 (I already had one on my digital sources across the room). The Triton V3 supposedly has greater transient current delivery capabilities and isolates each of the three outlet banks from each other, and I must say I found it to be a significant improvement over the Denali. Again, my electrical system is pretty rudimentary, so I don't know if everyone would get the same level of improvement. And I have both Tritons physically isolated on top-of-the-line Harmonic Resolution stands (for some reason, they're very sensitive to what they're sitting on).

But even my wife -- who is a very casual listener at best -- noticed the music coming from the system sounded clearer and more natural and wondered why.

Just saying.
