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.

FWIW, the line from the pole appears to be large wires protected by a plastic shield that is bolted to the pole. It goes into a large access box under ground beneath the pole. It's like a water meter box. From there it is underground in large plastic conduit to the meter. I don't know what guage or how many leads there are. I also don't know if there are connections in that box, or does it just give them a convenient access to fish the line back and forth. I'm sure they were not gentle with those wires. Not like us and our cables. The job was a one day joint effort between the power company and our electrician. I'm not sure if the Power co. wired to the meter, or just to the underground box. Wasn't there at the time, had to work.
YEs, I suppose a spectrum analyzer as opposed to an oscilloscope would be the right tool for the job of measuring AC line noise/distortion.
I hate this... forgot to take the meter home from work yesterday. You'd think that would be at the top of my list (and it was). Alot going on right now. Couldn't test the voltage.

Jim, did check out the box though. The breakers appear to be conventional. No test switch. Box is square D HOMC42UC. Breakers are marked: HACR type. HOM type. There is a 200 amp. main breaker.
Looks like I am boreing everyone at this point. Checked the house voltage and it was 120 or so volts during PM listening time. Certainly within modern specs. In comparison, the voltage in my shop across town where I work on the electronics (for myself, I'm just a DIY'er) and voice/test them is 119 or so. That building was built in 1979. So, not a huge difference there. Not sure what voltage in the house was before the changes.
Not boring! All the same... 200amp aluminum can't sound as good as OFC and teflon!
