The Goal Zero type of products are a battery and a pure sign wave inverter in a box. You can buy all kinds of pure sign wave inverters of similar distortion and buy batteries and chargers separate, as you need. All inverters will sound different from each other as they all have parts and construction that are different (every single thing you do makes a sonic difference).
I have been using a Yeti 400 on my highly modded Oppo 205 for many months....really sounds great. I have removed the cover, bottom and sides and removed the heat sensor from underneath the battery. Now, the fan never turns on. The fact that it is mostly open allows much more heat to be removed naturally. I did not remove any other heat sensors...just the one that sits underneath the battery. I tried plugging my EVS 1200 dual mono class D amp into the Yeti but the Yeti shut off as it does not have the surge capability to handle the onrush current of the amp. I will be buying a 1500 watt (3000 watt surge) pure sign wave inverter ($3-4 hundred dollars) later to run the amp. I only have those two components and when I get the inverter for the amp then I will be completely off the grid.
Yes, the power cord from the inverter to your component is still important. BTW, I also hardwired my power cord going to the Oppo inside the Yeti and I installed a PPT Stopit into one of the AC outlets. Those PPT stop its are crazy good....too bad they are out of business (at least for now). I bet the parallel conditioners from ADD-powr and Akiko would help on the output of the inverter, as well. Happy tweaking!
