You could use a bank of Group 31 marine batteries (use AGM or some kind of Lithium) and a large pure sine wave inverter. Charge the batteries only when you aren't using the system and you'll have the cleanest power but make sure to feed the whole system with the inverter, so you can eliminate problems that come from connecting to two different power sources.
Honestly based on what I was reading on this thread, and I am not sure if what I am regurgitating is accurate, but the UPS is kind of taking me off that grid. Honestly, I really notice nothing different, everything sounds great on my system.
Not sure if the UPS is any influence on all of this.
Just need all of you to realize that I am getting hit with a lot crap when you try to do research. So it is difficult to differentiate what is accurate or false.
We got that the power cable makes no difference, even based on what Gene said. I trust research and science, so that is why I am laying back on the drama. I did not proceed on purchasing my cable. But it seems like many people have a lot riding on the cable portion itself. Than we got power plugs themselves where people say there's a difference there, not sure if that's accurate. Like gold vs rhodium plating, etc.
So it's kind of difficult to figure out what's true, what creates any change, if any.
But again, it's my opinion and I am not professional. I more or less fell into this further by actually listening myself. I got some focal clears and a decent setup for my headphones and a tiny bit of common sense.
I was watching this audioquest testing of power cables on a system at an audio expo in England I believe it was, and as Gene had stated it's hard to really notice a difference especially when it comes to switching cables and delay. Which is very true, but in that video I was listening for differences on my headphones which are actually able to pick up differences or it did, in my experience.
So I listened to everything from song start at every single cable switch. With no delay really more than maybe half a second, listening and jumping to the exact point where the new cable is added and the song plays.
Just with that I can honestly hear differences between the cables, so I am not sure what or that is accountable.
Honestly the jump dies after like mid range tier. The Audio quest Y3/Z3, which is like a $179/200 is where it makes the most noticeable difference. That I hear, after that the difference is very nominal and paying those 1000's is ridiculous.
Second, even people who just post these video's of I just bought this cable and they run a demo. Using the very same method, only listen when the song plays OEM cord vs Audioquest lower end tier cables. I am hearing a difference on people with trash ass systems that are old to new and advanced set ups.
The next test was using the same line up Audioquest power cords, but using a power conditioner from audio quest.
With my experience the best setup and sound after numerous test listens of all of them via sound comparison with something[quality headphones] you should assume will be able to actually give you the ability to hear the difference.
Was the Audio quest monsoon cable to the power conditioner, which wasn't a variable, that was the only cable they used for the conditioner and the Y3 to the amp. That was the best sounding of them all IMO. That's a lot of money though.
So I honestly dont know what to say when I am noticing am auditory difference.
Now on the other hand, the very same test using audio quest speaker cables. This is at a second show, completely separate from the power cables. I honestly hear no difference, it's very very little difference. Absolutely not worth it beyond a doubt.
So when it comes to the power cables, and I mean it's a convention center or whatever it is, is obviously running romex or whatever they use in england all the way up to the wall plug is and there's difference.
Without a power conditioner the difference is very subtle. I would say it's not worth it
So this is my opinion, and it's going to be hard to defeat what I am physically hearing. I am not sure if the person who is making the video is editing it or doing anything to modify the sound, which is always a possibility. But the person doing the videos was not associated to Audioquest and has plenty of videos doing reviews and things on different audio products.
I believe he is a very popular audio reviewer in england.
This goes directly back to what I said earlier, I watched a video on power cables way way before I even had my AVR, just researching as I was planning on making my purchases. Just merely looking into different factors and variables of home theater audio. The frequency seems to change with legit cables, not sure what part of the cable is creating this. Whether it is the power plugs or whatever it may be creating this difference.
Would I suggest purchasing a power cable, nope. I would though suggest you DIY, save yourself a ton of cash and get the same results paying as much as those entry level cables for a cable that would cost a 1000 if they made it for you. I see the prices are way too inflated when they do it for you and that makes absolutely no sense. It's not rocket science, just being lazy.
All of you have valid points, I am not here to argue. Just giving my opinion, and considering yours I did not proceed to do this as it seems like an investment that can go to better things. But for anyone that does have money to blow, might as well try it and if you dont like it or notice any difference just sell the cable. Otherwise enjoy the change or placebo, but dont spend 1000's to do it.
