Sound Better w/Amp Directly Into Wall Then Thru Zero Surge


I’ve been breaking in a Pathos Classic Remix. It’s lovely at small things, but when things got complex, the soundstage flattenned, the sound compressed, and the top end got sort of hashy.

 

When my last amp and speakers got fried from a surge, even when plugged into a Shunyata Hydra, I decided I needed some more serious surge protection. I was directed to a Zero Surge brand protector. I have been plugging the Classic Remix into the Hydra and that into the Zero Surge.

 

My previous amp, a Unison Research Unico was quite improved going through the Hydra in terms of the sound, but, again, that was going into the wall.

 

With the Classic Remix plugged into the Hydra (and the Zero Surge), I decided to plug the Classic Remix directly into the wall. Immediately there was an improvement with the dynamic bloom and lessening of the harshness when the music got big.

 

I’m wondering how much the Zero Surge was reining in the dynamics? I need to try comparing the Hydra directly into the wall with the Pathos plugged in, as well as trying to plug the Zero Surge directly into the Zero Surge. But, boy, it seems as if something was limiting the current to the Pathos.

 

But I have heard that some manufacturers say to plug their apps directly into the wall. How do I protect my equipment (without going to crazy expense)?

 

One other thing - I called Zero Surge and Jim, the guy I spoke to, told me that there's nothing in the Zero Surge that would cause it. "It's just wire", he said.

Interesting to me (and to the dealer) is that the sound seems to be changing, possibly depending on the time of day. At least this morning, the sound was emphasizing the top end of things. Aspects like cymbals and sibilance were quite pronounced. The bass was fairly tight. 

 

Mid-afternoon, however, the top end was tamed and the extreme bottom end seemed bloated. I heard it through the headphones as well as the speakers, although the bloat was more apparent through the speakers.

 

I'm planning to keep a journal for a couple of days to see if this change is consistent, and consistent with the time of day. 

I'm not sure I understand your question. 

Right now, the Classic Remix integrated is plugged directly into the wall. Everything else is plugged into the Shunyata Hydra, which is plugged into the Zero Surge.

analog, why are you daisy-chaining one power conditioner into another? The end result will be a loss in SQ due to excess filtering and circuitry in addition to extra cables.

I'm not. They are two different beasts. The Zero Surge is only a surge protector. No power line conditioning provided.
