Objective Opinion? I think I've found it!

Congrats to you and your dog!  I have high quality power conditioning in my system (Shunyata Denali) which is a definite improvement, but late night still sounds better to me.  Not all the time but often

Do you have your amp plugged into the conditioner?  I do not.

I want my 60 seconds back.

@carlsbad, OK here is your 60 seconds, use it wisely this time.

Here's a kind of related post I made 20+ years ago (I was indeed using a power conditioner with that setup)...

Is Audioreview the Bose and Grand Enigma reviews? Anyway, here is a mishap that happened the day before Christmas in our household. I would not recommend this CD to cat owners. I have copied and pasted the following from a previous email...I picked up a holiday CD at a thrift shop that is entitled "Jingle-Cats", real kittens singing 20 holiday classics, from "Silent Night" to "Auld Lang Syne". I had thought that the cats (the little men) would enjoy it, but by the time the second song had finished they were in an uproar. One had sprayed one of the speaker stands and two of the others were trying to attack the speakers (that are on 29" stands). It was a total disaster. I had to put them outside and then later keep an eye on them around the speakers for the next 24 hours, as even with "normal" music playing they kept eying the Reynauds. Finally their tiny little brains forgot all about it and everything is back to normal (normal meaning that they are now peeing the Xmas tree that I brought home yesterday morning)."

@dekay It's a good thing their memories are short!

@tomcy6  Yes, the amp is plugged into the conditioner. It makes a clear difference.

Does your dog have moods or different activities day vs. night? The change could be on the subjective side. Just a thought.

@hilde45  She has been here two years and has never reacted during the day until the day after installing the PST-8 and filter.

My male cat has never had any interest in listening session, sleeps well away from stereo, the female loves to listen. Goes to show some women love high end audio.
