Hermes added, question

Hi, All,

 

Just a follow up on my thread last week about adding Hermes to my Pontus. All is connected and playing. I did do the left and right speaker check via Qobuz test tones and all are playing properly. I haven't sat for a critical listen yet as I want to give more burn in time. So whilst I'm not quite ready to give my impressions on any improvements, I did have a question.

 

I noticed on some tracks (not all) playing only when listening through my streamer (connected via USB running from Eversolo DMP-A6 Master into ADD-Powr Symphony In, then out from Symphony to Hermes USB In. Using I2S connecting between Pontus and Hermes. What I noticed is that on some tracks while streaming I detected some static/noise through mostly my right front speaker. I didn't notice this using Coax (CD player) or Optical (Brennan B2). Just on the streamer and again only certain tracks...

 

Any idea what could be causing this? Is the ADD-Powr possibly the culprit? The static/noise was never there before Hermes and I had ADD-Powr Symphony connected as above only direct to Pontus...Music still plays but on higher volume the noise is audible...

It took me months to solve this same problem I experienced. I had an ADD-Powr (non in/out version) installed in my main system with the antenna only a feet away from my equipment rack, and I hear occasional spikes and noise on certain recordings. This happened with both my Berkeley/Esoteric and Terminator/Hermes chain. After going around in circles with wrong diagnostics, I finally removed the ADD-Powr and the noise is eliminated.

Now I’m using the ADD-Powr in my secondary Khama based system with unit and antenna 6 feet away from all equipments. Improvements are still heard. Our systems may differ and so will the results.

@mosler666  Thank you! I removed the USB connection from ADD-POWR Symphony and went straight to Hermes. I also changed the setting to 001 on Pontus. Whilst this seemingly did the trick, I heard the damn static again. It's only there on certain tracks not all. I am going to try removing the ADD-POWR as you did. Thank you so much! I'm hoping this does the trick. I too can move it to a second system I have as well. I don't know why I even suspected the ADD-POWR was maybe the culprit. But I have tried everything including going through all the settings on my Pontus a couple of times...So frustrating because the static only pops in occasionally and seemingly so randomly...

 

Thank you, my friend. Not gonna lie this has weighed on me a bit. It's the randomness of it that had stumped me. I'm going to move the Symphony and see if that does the trick. Fingers crossed...

It’s funny how this goes down as it took a day or two after removal of my ADD-power before spike/noice to totally disappear. Have no idea how they work especially my unit wasn’t in the signal chain.

Just a little off this topic. My PS Audio Nuwave Phono A/D refuse to work with Bybee in-line filters coming from my turntable. So those who say tweets like these doesn’t work, at least they make a difference.

Hope removing the Symphony does the trick for you.

Wishing all Happy Holidays.
