The sound of my new electrical service: Day 1


And I mean a completely new service. New pole!, new pole transformer!, new underground line to the house (was above ground), new meter, and new breaker box with all new breakers. House wireing remains the same. Talk about an upgrade! Or, will it be a sonic downgrade? I wouldn't be surprised. House was built in 1964, so that stuff was 50 years old.
I don't do much desk work, so typing all these subjective impressions will be quite a bit of work for me. I hope we all can find it interesting at the least. I doubt too many others will have to go through this with their systems, so maybe it's pointless, but might still be interesting. Beforehand, my system was sounding so good that I was afraid to change anything. You know what I mean don't you? If not, I'm sure you will get there eventually.
System: completely restored, vintage tube. Been through the modern stuff, this is the real thing. I will stick to digital VIA CD for the first few days to keep things simple for us.
Day 1: Eric Clapton "Unplugged", Buddy Guy and Jr. Wells "Alone and Acoustic", Ani Defranco "Living in Clip"
Right away I noticed the urge to turn the volume down. I'm usually inclined to turn it up because this system can sound so deliciously juicy with real life timbre and tone. Not sure if it now plays louder at the same volume setting, or if it is just more irritating. On Unplugged the instruments have lost that deliciously right timbre and tone. Total lack of analog like sweetness and the system could even be mistaken for solid state. It has aquired a solid state like impression of power though. Foot stomp/tapping is more audible with a bass like presence. Sibilants, S's are pronounced like they linger too long. Capton's voice is both murky and harsh at the same time. Overall, a great loss of transparency that makes this obviously a recording and not the musicians in my room.
On Buddy Guy, a lack of clarity on the voices. Also irritation when things get peaky. Jr's harmonica is dark and lacking the usual bouncy excitement. Guitar tone seems lacking in higher frequencies. Again though, I hear more intense feet to the floor sounds. Need to play something with bass to see what happens there.
On to Defranco's live disc. If you have any interest at all in this artist, just buy this one. You might not love all of it, but the good stuff is just great. On this disc, the energy is all there, but on the irritating side when things get loud. Voice comes off better than the other two discs, but not at all what I am used to. Bass? Well, it seems tighter, but not better or stronger. Her guitar rings out as usual with plenty of power, but, again the timbre is off making everything less interesting. When the music quiets down, a perception of transparency sets in that approaches what I am used to here.
Thats it for now, stay tuned for day 2, etc. to come.

I would give it at least two or three weeks to settle-in. I would expect the grain and semblance to subside during that time and the separation of instruments to tighten up. This is not dissimilar to buying new equipment or cables.

Did they make any changes to your Ground or internal wiring going to your music room?

Hang in there!
and new breaker box with all new breakers.

Manufacture? Style number?

Breakers, AFCI? Do the single pole 15 and 20 amp breakers have a TEST button on the front of the breaker near the off position side of the handle?
Look anything like this?
Square D Homeline AFCI

I gotta believe .. or maybe hope ... that the new AC utility transformer is breaking in. What else could it be? JimMc ... if you pick this thread up, what are your thoughts??
I agree with waiting at least 2 or 3 weeks for things to settle. If you did not have your ground rod replaced, I'd give serious consideration to doing so. Ground rods corrode over time and if it has never been replaced your house may be effectively without any ground at this point, which would explain a lot given that you've basically upgraded everything (except perhaps the in-wall wiring) and you may be hearing your system without the benefit of any ground. But, give it a few weeks first to see if any of it levels out. BTW, what part of the country are you in?
Yes , you are going to have some new growing pains. Give it time, It will settle down. If anything , after a month or so re tighten the set screws on all the new circuit breakers also neutral and ground buss bars screws too. . Good luck
