Clean AC power


The power to my house comes from the pole on the road, then underground to a large box that I assume is a transformer. This supplies power to my house only: there are no other houses within 1000’. Does this mean that I am getting very clean power?

Miller, you use the phrase "a little common sense" like it actually pertains, here. Some of the smartest people I've ever worked with were some of the most ignorant people ever when it came to household electricity. There's no magical common sense involved, a person has actually been taught, or learned, or not. The average homeowner that looks inside an electrical panel doesn't know the first thing about it. I'm not for an instant suggesting they can't learn, but it's nothing to treat in a casual manner.
Some good recipes given.  My pathway involves PPT "The Gate", OYAIDE SWO-XXX ULTIMO Wall Outlet Receptacle with carbon fiber wall plate, Patrick Cullen Crossover II power cords and Decware Zen Power Conditioner.

This has all been quite effective lowering the noise floor, blacker backgrounds and improving attack.  I've no dedicated line.
Electricity in an electrical panel is
nothing to treat in a casual manner.
.On that I can 100% agree.
Hello,
+1 on the Puritan PSM156. They also have a couple of other products you can add to fix the ground going from your system. I own 2 Puritan PSM156 and the Ultimate XX power cords. This is a great place to start. If you demo it get a fully broken in unit. This takes 12 days. After you plug in your gear you will need about 12 hours for your caps to charge back up in your gear. The filtration in this thing is insane with no negative sound effects. Just pure bliss. If you have an electrician modify or add a dedicated line have him put it on the side of the panel with the least amount of noise. No refrigerators, no HVAC units, no washers or dryers. Basically things that create noise and are on a lot. Power cords make a huge difference going to your equipment to help with RFI. If you are in the Chicagoland area and want to demo the Puritan this store lets you try before you buy. https://holmaudio.com/
Be warned you will sell anything to buy this. At $2300 it’s not cheap. It’s just perfect. I replaced my two Furman power conditioners with the Puritans. 
How to achieve clean power?
1. Establish an earth ground. 
2. Set up a dedicated circuit.
3. Plug an ADD-POWR Sorcer X4, an AC harmonic resonator, into an outlet in proximity to the breaker panel. If sockets are needed then buy a quality AC power strip.
The problem living in a narrative driven "reality" people become accustomed to making up whatever story they like regardless of the truth, it becomes "their truth" and on they go their merry way off into fantasy land.

I never said be casual. I said don't be a fear monger. 

Including slimy twist the words around fear mongering.
AS an ex-pshrinck, I suggest you spend as much as possible, because you will need all of the placebo effect you can muster to miss any "noise".
I have been a long time believer in the benefits of AC regeneration. I used to find that I would get the best from my system late at night, especially in the Spring and Fall when the demand on the power grid was at a low point. For the last several years, I have had a PS Audio P20 in my system and regardless of what time of day or season, I get super clean power with a very low impedance-and my system sounds consistently great. This is a fantastic product and in addition to helping create an incredible sound stage and amazing micro detail, because of the low impedance and ability to deliver peak power, I don’t experience compression with loud complex musical passages that were a problem in the past. I have tried all kinds of filters and some very expensive conditioning products and I prefer the P20 hands down. One other point, I do have a dedicated 20 amp line with #10 gage shielded wire running to the P20.  Also, the AudioQuest Hurricane Power cords don't hurt.  I never believed in power cords having an tangible effect until I did some A/B with the AudioQuest Storm line.  Don't think I would drop $30K on the Dragons to outfit my system but any of the Storm series is highly recommended.  
Get a good dedicated lines.
Do not plug amp into filter box etc.
Go directly into the dedicated line outlet
Life-saving tip: If you see someone get hit by lightning or is otherwise electrocuted the lethality is due to the heart going into ventricular fibrillation. Therefore, you should check for a pulse and if absent, do a precordial thump, which is a fairly hard and sharp blow to the sternum. Do it once and check for a pulse and if there’s no pulse, do it again and check for a pulse. If there is still no pulse, start chess compressions and get help. If you are uncomfortable with a precordial thump, go directly to chest compressions after checking for a pulse.

I had an old power wedge & decided to try a conditioner to see if there was improvement.
I got an iFi power station with the two additional I purifiers.

It made a significant improvement in soundstage imaging, blackness & clarity. More improvement than I had expected.

I have reference level cables & I think that helped to realize the improvement.

Really glad I tried it cause the improvement it made in listening to just my MD102 tuner alone was worth it…
I have found tremendous benefit from cleaning the exterior and interior power.
I ran 3 dedicated lines.  I found putting my mono amplifiers on one line, my digital on another and analog on the third.  I have a Denali on the analog and PS 10 Powerplant on the digital.  I have found changing the settings on the PS 10 to have a lot of influence on the sound.
I have removed all SMPS power bricks from the above lines and run them on a house line.  I found  the SMPS injected significant noise and caused ugly distortion.
I have an Akiko Corelli on the Denali, it dropped the noise level.
I have LPS's for as much gear as I can.
I highly recommend PS Audio Powerplants. With their direct puchase plan you can return it in a month for a full refund. Trying them out in your system is the only way you'll hear the difference.
Consider a Lamm ML 2.1 or 2.2. The second power tube serves as a rectifier which cleans up the sound considerably. 
I recently added an Ifi Powerstation with a Nordost Blueheaven power cord and I was shocked by the improvement in tone and detail in my system (Pi2AES>Hegel H190>Tekton Lore).  Until this change, I was underwhelmed with my system but I'm now extremely happy with it.
I know that the cleanliness of everyone's house power is different but if you have a chance to audition one, with free returns, why not.
