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.

I have a 15amp Shunyata Python power cord running out of the Hydra.

 

I, too, have been an owner of a Hydra 6 for over 20 years. It was only this past September when something occurred. The tech surmised that the Unico must have been hit with surge. That is what it looked like to him. Whatever happened, it fried the soeakers' voice coils as well. Did it start with the amp, or did it come through the wall? I don't know (Is the former possible).

 

I talked with a couple of people in the business and they said that MOVs, which are what is in the Hydra, provides only so much protection, and more protection through transformers is better.

Yes. A conditioner can be distinct from a stand alone surge protector, which is what the Zero Surge unit is.

 

So I did try plugging the Pathos directly into the Zero Surge. By ding do, I lost some openness, a bit of distinction between instruments in the soundscape, a bit of flattening of the soundstage. The treble, in addition to losing a bit of openness, is less smooth plugged directly into the wall. Overall, the amp’s sound has lost a bit of its magic, and sounds a bit closed in and tight. 

 

So I’m wondering what is happening in or to the amp to cause this change in sound? Again, the rep from Zero Surge today said that there shouldn’t be any difference. "It’s just wiring."

Yes, then the question is, how do I protect it from potentially frting without worsening the sound?

 

The power strip with no filters will protect it with no worsening to the sound? 

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.

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