That reviewer also reviewed the PS Audio P20 ($10,000) and found the $20,000 Stromberg slightly better.....but now equaled by the $450.00 Goal Zero. That reviewer now uses a Yeti 1200 for his X250.8 amp that he has in the closet to get rid of its fan noise (my friend is in communication with the reviewer). The all in ones are made to be used out doors or in your garage. The lack of heatsinking makes the fan come on with very little current being drawn. If you use high powered separate inverters they are essentially a giant heat sink and the fans generally don't come on till your drawing half power (not many people need 1500 constant watts in their system). You can also cool the separate inverters by running a silent fan across the inverter chassis powered from your noisy grid.
Every person that I know that has an inverter (Goal Zero or separate inverter battery combo)......pretty much says the same thing. Way cleaner sound......blacker backround, more subtle detail, better depth and height, decreased grain.......just plain purer sound. I use a modded Yeti 400 (naked so the fan will not come on) on my front end and will be getting a separate inverter for my power amp. I was talking to one old customer of mine and telling him about inverters and he said he had bought an 800 watter 3 years ago but had not tried it. 4 days later he calls me and is raving like a maniac. Says his system has never sounded this good plus the colors on his led tv are now out of this world.
All inverters will sound slightly different. They synthesize the waveform and the output is filtered through a coil and cap. Back in the 90s I modded Exeltech low distortion sine wave inverters by changing the cap on the output to Wondercaps. My friend Alan uses the Yeti 3000 for his whole system but has a 3000 watt Topaz balanced transformer after it. The reason he is doing that is that the Topaz was already being used and had super expensive Furutech connectors and Triode labs wire on it (I soldered all the connections for him.....he lifted it.....80lbs?). He is not sure if the transformer does much now as he does not want to remove it. He used to use a Synergistic power cell with the transformer but the Yeti killed it. He bought the Yeti 3000 instead of a separate inverter/battery bank because he wants to use the Yeti as power back up for his entire house when PG&E decides to turn the electricity off for several days because of high winds (they did not like the law suits after all those fires a couple of years ago). i have not seen the waveform measured on an inverter for broadband noise. This is why I suggest using a "cleaner" afterwords. However, used alone....they make your system sound mucho cleaner.
If you look at the review of the Puritan I linked above you can see OCD guy checked the noise coming out of the Puritan versus coming out of a normal line and also a dedicated line. The normal line was pretty noisy, his dedicated line was less so and the output of the Puritan would not read anything on the meter. If you search for Puritan on Youtube you will see a couple of videos of the Puritan guy at shows where he has a display showing the noise coming out of the wall and then he plugs the socket into the Puritan.....and it is just slightly more noise than the residual of the measurement machine (mirroring what OCD shows). The reviews on the Puritan are all raves......and I don't remember any of them talking about soft gooey sound (your fav....he he)
