+1 I have heard a few stories of attempts at using general purpose power supplies for audio equipment. It does not work. The kind of power needed for audio systems has extremely tight tolerances. When a product is made for the audio market it is purpose built from the ground up and ends up costing a 10x. This is why a good power conditioner runs over $5K. Incorporated in my streamer is a battery and charging system... part of the $22K price... I am not sure how to partition the cost... but it is definitely in the thousands.
Goal Zero Yeti 500
Hey Goner’s,
I’ve finally decided to stop buying anything else until I purchase a Goal Zero Yeti for my ESL’s and my front end components. There was an audiophile article written in around 2018 about how effective this generator is. Fortunately my ASR power amp runs on two power supplies and a battery so all that I’ll be plugging in will be my Ayre QB9 Twenty, Bryston BDP 3, Two Quad 2905’s, ASR Mini Basis and Thorens TD160. There are only two receptacles in this unit so I’ll either use a general heavy duty power strip or a passive PS Audio Line Conditioner. I still plan on using the Akiko Audio products that I purchased over the years. The Yeti advertises that it is a sine wave perfect device and it sure makes more sense to me to buy one of these generators for $500.00 than spend crazy money on an expensive line conditioner. Has anyone tried one of these sine wave battery powered generators? Does anyone have insight about using this product? Thanks!

@bigshutterbug @sns Well that’s discouraging but I appreciate your input. I’m surprised because I spent time building a respectable car stereo and always considered the fact that it got its power from the car battery an asset. Additionally, the review that I mentioned stated that there was no audible difference between the Goal Zero and the $30,000.00 Stromtank but maybe the Stromtank has the same effect that you’re mentioning. The other thing however is that I don’t hear any reason to invest in a better power conditioner than how I’ve tuned my stereo as it is. I was playing a Rubenstein Chopin Mazurkas remaster on RCA for a pianist friend and we were both floored at how good it sounded. Maybe I should just focus on buying more music. Thanks again for sharing. |
I can’t speak directly to the Goal Zero 500 but the 1500 really opened my ears to realizing how much my wall power was effecting the sound. I tried the 1500 on just my front end and it was ear opening to say the least. Out of curiosity I also tried my power amp with the 1500 and the loud inverter fan kicked in after two or so minutes, lol. Even with the amp not being compatible, I knew I wanted to hear everything off grid which led me to where I am today. OP, I’m guessing you and others here have experienced the ups and downs of our systems sounding great one day/night and then brittle and thin on another. After going the battery route, the consistency of my system isn’t something I think about anymore because it sounds great no matter when I use it. I now understand that the demands on our power grid at different parts of the day can seriously effect the quality of our sound. I won’t presume to know all the technical reasons for this, I know because I’ve tried it.
For reference, this is my gear: YG Acoustics Carmel speakers, Pass Labs X250.8 power amp, Pass Labs XP-22 linestage, Luxman EQ-500 phono stage, George Merrill Signature Polytable, REL S/510 sub, Border Patrol DAC/Bluesound Node for digital. These all plug into a Puritan 156 and then into a Giandel 5000W pure sine wave inverter and Lossigy 400ah Lifepo4 battery. Not once in almost two years of running this setup has the inverter fan kicked on. The site below is where I got a lot of useful information, it’s not my exact power setup but it’s close.
I know my particular battery setup isn’t exactly what you’re asking about but I wanted to put his out there for people interested in the topic. No matter what you decide to do or try, good luck to you!

@drack1 So the battery powers the sine wave inverter, straight forward enough. You spent some money putting those components together. Thanks for sharing and thanks for the link. |
