High End Audio powered by Solar vs Grid

I have a 1050 watt home stereo I use on my computer with a pair of 15" and a pair of 12" speakers and surounds too.

I can't tell any difference since switch from grid to the sungold sound wise...
1050W ! ouch... I'm not surprised you can't hear any difference! 🧏‍♂️ Hope you've been wearing ear defenders 🎧
With my electronic engineering hat on, I'd say that a good system should have a power supply that is good enough to filter and smooth out any minor fluctuations in the supply feed so that you can't hear a difference.

The issue these days is that manufacturers use designs that focus on maximising reliability and minimising cost & weight rather than using a design that is immune to fluctuations in power supply quality.
That is a good point. As to weight, I always found that when it came to stereo components, the heavier the better. I'm not saying making it heavy makes it better, but better sounding equipment always seemed to be pretty beefy, with few exceptions.

Yep - beefy coils, transformers and big capacitors is the way to go 🏋️‍♀️
In a better way.
Hey mannnnn. I have been in and out of the high end audio and sound production since 1972…. if it sounds better, count your blessings… hush…let it go…The whimsical audiophile Gods may decide to just mess with ya. They and their rabid cousins ,recording engineers ,are an insufferable bunch anyway…
I have seen and heard of what you speak… , but it’s rare….usually gremilins mess with ya , not help ya…don’t jinx yerself…..shhhhhhhhhhh..

btw, I’m envious.👍
Almost all modern amps are Class D so sine wave or square wave or anything in-between makes no difference. The audiophiles are well known to have these ticks that the smallest differences will cause artifacts and will argue till the end of the earth it matters :rolleyes:.

I've built systems from 100's to mid five figure of watts, when I was young also was a sound guy for bands on the side. Only issue I had to deal with was poor grounding or differentials from one side of a building to another, isolation transformers of the the line level signals took care of that.
I'm running a pair of refurbished / enhanced Adcom's GFA-5802's.
Class A at low levels and Class A/B everything above.
All of the system components are exactly the same as before.

I don't proclaim to hear the difference between a $100 RCA cable vs a $1k RCA cable.
However, there are a few slight but noticeable differences that I've picked up on. Using the wife as a test subject (her being unaware of what she was doing this for) and a song that she is very familiar with, immediately she said that it sounded different. The dissection of the instruments she said was much more audible than what she had heard before.
For reference, I played the Eagles Hotel California in 24bit FLAC format. The intro is noticeably different on that song.

Not every piece of music sounds better. There are however some really amazing recordings that do reveal some differences that I haven't noticed before.
Just for the record, I will state that my whole environment is vastly different than when I was living in the city.
I'm in an area now that has pretty much nothing around me for miles (except for a couple of houses) and a home that is of completely different construction than what I lived in before. I'm 100% sure that has an effect what I hear and don't hear now vs before.

Now it's time to really enjoy my music, like I intended it to be for years now.
There can definitely be a difference in sound depending on if the 60 Hz line has sharp edges that might get into the audio signal. In my experience, the worst offender is a modified-square-wave inverter. These have sharp edges that you might hear through your system. In the early 1990s when I was still in the pro-audio business, I made a 12 watt sine-wave inverter that powered a microphone preamplifier to be used in Africa to record different tribes. Mainly drum and vocal sounds. A modified Square wave inverter was clearly audible where the sinewave was not.
A REAL good piece of audio gear will IGNORE the AC waveform and turn it into pure DC to operate the audio circuitry.

But that HF noise seems to find its way into the signal chain sometimes.

As for warm sound or subjective audible qualities besides the induced noise, it's the same old audiophile biases I'm afraid.
Our hearing changes not only from day to day but from 5 minutes to 5 minutes a lot of times. Aside from a double blind A/B/X test, it is hard to tell what is really an audible difference. If your test comes out to be 50/50 % right, then you are just guessing.

I spent almost 20 years specifically in the audio design business, both pro audio and recording studio/live sound (+medical). Noise and audio quality was very important. I heard differences I thought were real but were just my (and others) opinions. Like, absolute polarity difference. For days I thought for sure it was something I could tell the difference of.

Noise from the AC line might be audible though. The soft clipping of the grid voltage is most likely not audible.

BTW, I mainly use Mackie HR-824 power studio monitors for almost everything. They used to be built up here in the pacific northwest.
