I now have a Core Power 1800, having worked my way up from 300 to 600 to 1200, and finally the 1800. It's a really great power conditioner until the next best comes along, and we know it will
Sell your $$$ cables and conditioners... affordable LITHIUM is here!
I've been an addict since my first system of KEF Concord speakers, Crimson Electric amps and an Ariston turntable back in college in '81. Since then I've been down the entire Linn system with Active Kabers, Full Meridian active system with DSP5200's as well as some burly NZ Perraux mono blocks with Sonus Faber when I lived in NZ. Since moving to the US in 2001 I've been through years of altercations between solid state camps from Bel Canto, Levinson stereo 336 to mono 436's, 532H and Mac 452 to speakers from B&W 802N and D2 to Wilson Sophia 2's, Sonus Faber Amati Homage and Revel Studio 2's. I've tried conditioners from Transparent, AQ Niagra, Isotek and others and every time come back to a decent cable straight from the wall.
Three years ago I took the plunge and went down the Devialet rabbit hole, streaming direct from a MacBook Air with ROON my Devialet D200 (soon to become a D400) drives my Focal Utopia Diablos via Analysis Plus Solo Crystal 8 speaker cables (and that's another whole can of worms with enormous cable differences), a JL Audio Fathom F110 (also about to be doubled up) rounds it out. My livening room is about 22x25 with 10ft ceilings and partially treated as best I can accommodate.
Suffice to say, I've been around the block with hifi, listened to way more than my fair share at dealers and friends with diverse systems and currently run one of the most reveling systems I've ever heard. Sure, there's not that thick syrupy warmth the tube guys will clammer for, but then I'm hearing so much further into not just tonality but intent within the playing.
If you read the review in Enjoy the Music from Tom Lyle, you'd see he equates the GZ Yeti to the $30k Stromtank. His review was the $400 Yeti 400. The Yeti 1000 was $1099, the 3kW Yeti 3000 is $2999 and will power almost anything. So, like Tom I took the plunge and bought a Yeti 1000 figuring it'd have plenty of 'headroom' for my meagre 600w consumption. (Though I have since plugged my JL Audio Fathom in too)
After playing the "FedEx f'ed up" again game, I finally went to their depot and picked up my new toy myself. After a handful of songs to establish a baseline for the evening, I simply plugged the Yeti 1000 in, reconnected the Devialet and sat back... My girlfriend was first to break the silence and then immediately regretted it as I couldn't help myself interrupting her for the next half hour of gushing over what a profound difference it was making.
H-U-G-E. Truly component level and an absolute game changer.
I was immediately texting my good friend with his PS Audio Directstream, Gryphon Diablo, Audio Physic Avantera III all powered by the latest Synergistic Research Powercell 12SE and Gallileo power cord with AQ Hurricane to each component - SELL- SELL- SELL it all, get a Goal Zero!
We stayed up until 2am listening, flipped it back for a handful of now unlistenable tracks and then back again to Yeti 1000 happiness. In over six hours of powering my Devialet and Fathom at 90+db levels it'd dropped to a laughable 98%. I'm guessing that means it'd run off the grid for 300hrs or more? That's probably a several months of listening for most people. Who even cares, it simply sounds spectacular and the single biggest improvement I've ever heard from anything less than a major amp or speaker upgrade.
I know my system is fairly frugal and green running, my buddy Matts, Gryphon would probably need the 3000W Yeti as his amp pulls 1900W at full song and his full stack of components albeit front end certainly add a few hundred more. He's headed down to me in a couple of week with a stack of exotic power cables and conditioners to try and I can't wait to share my results - I'm guessing he'll want to steal it away for his own demo right after. I would imagine he'd even get away with the Yeti 1000, so long as he doesn't run it too hard?

eliz. I feel you girlfriend. I basically gave my PPP away after having it fully rebuilt but still had fan issues, even when the system wasn't playing. I just didn't feel right selling it for $800, so I sold it for $300 with full buyer beware cautions. I now have a Core Power 1800, having worked my way up from 300 to 600 to 1200, and finally the 1800. It's a really great power conditioner until the next best comes along, and we know it will |
My french dac Nos of Starting Point Systems Tda 1543 is designed with an internal battery that I connect to an external lithium battery with great results...I charge it one in a week...Then I love my lithium battery... I had already treat all my electrical grid with passive filtration with stones and crystals, the amplifier is connected to the wall with a power conditioner... The results when you have a cleaned electrical source is awesome... For me the cleanliness of the grid, the house grid and also the audio grid, is THE most important upgrade... If I had money I would buy a yeti for my amp but the fan and the price is a no go for me...One thing is certain, audiophile change their gear often because their equipment is never at his peak quality potential because of the noise floor of their electrical house grid and their audio grid also... |
I have been using my Yeti 1400 for several weeks now and the fan has not activated at all during play with my Ayre AX-5 / QX-5 drawing a combined 150 to 170 watts. Longest listening session has been 6 hours. The only time the fan activates is when I am recharging, which I do after and not during play. The soundstage and many other aspects of SQ have continued to improve as if the Yeti is breaking in. Yeti is connected to an Ayre L-5xe power conditioner. Fan has not been an issue and SQ improvements have been significant. |
glennewdick said: Anyone know what the quality of AC coming out of the Yeti is like? all good to have a power generator but if its as dirty as the wall why bother? I don't doubt anyone's experience here but I would like to know the quality of power coming out of this unit. I also don't understand any of the science behind lithium for power vs. lead acid or plugged into a power conditioner. I use balanced power for my entire system and am very pleased with the results. How would lithium batteries improve upon that? |
I called Goal Zero and asked them a few questions regarding to the db rating of the fan, and output distortion. Here is their email response: I was finally able to catch up with our engineers and they have informed us that the fans can get as loud as:
-45db at ½ a meter
The AC inverter has a distortion rating of less than 5%. Hopefully this is helpful! Let us know if you have any other questions on these.
Thanks for supporting Goal Zero!
Best, Brogen Reed Solution Center Representative Also after doing more research, it looks like this lithium-ion battery power supply might be a better option. https://inergytek.com/products/apex It’s lighter, it charges a whole lot quicker, 500 watt max input, it has six 120v outlets. From what I’ve heard and watched on YouTube videos, the fan is very quiet. Can also daisy chain more lithium batteries. It’s also on sale right now, plus an extra 20% off using special code. Total sale price is $1300.
