Is 15amp 120v all the same? Battery Technology

I had a situation where the power went off in the neighborhood for some time. Thought maybe I’d try to see how my second system would sound like with using Goal Zero Yeti 1500x Portable Power Station 120v 16.5amp(size of a car battery). Surprise that it sounded as good as the power coming from the wall.  I’m a believer in the benefits of clean power, quality cabling and maybe the need for power conditioners. I’m using Furutec e-TP609 NCF Power Distributor(not a conditioner?). Maybe that levels the playing field. I’m curious what others think about the battery setup vs standard home power.  Is 15amp 120v all the same?  Is the Goal Zero Yeti well advanced with battery technology or is 15amp 120 is the same no matter what?

Before I sent this I, I by passed the Furutec and when direct from battery to amp. Similar or same sound quality on both approaches

Sorry about the last post. Did not mean to have such a large font and be bold.

Accuphase E-4000 (A/B), T + A MR 2500 R, Harbeth Super HL5 Plus, and a mix bag of cables.  Being an A/B amp, it draws very little power, 54-66 watts, and 4.9-6 amps at 70 dB at 7 feet.  The Yeti, iPhone, and dB app software are not calibrated, nor do they need to be, for this exercise.

The battery serves as a backup in case of a power outage for the fridge and a light or two. The chance of the power going out is rare. Only twice in 5 years. As for testing the battery with an amp, it was more of a curiosity.

Makes sense about good power conditioning and beefy power station.  I never thought about that. Thank you for your well laid out responses. As for the neighborhood, it’s a large planned community 5-30 years old. All power underground. Multiple sq miles. Closes commercial building is about 1+ mile away. Have modern solar power system with no battery backup. Zero issue day or night. I have tried the battery a few times. At most 3 hours.  There may be some unseen risk that the battery can damage the amp so no need to drain battery to zero. So, I’m done messing with the battery hook up.

What surprised me the most was the amp pulled only 53 amps at a fair volume. Harbeth Super HL5plus XD is rated sensitivity is 86dB 6 ohms.  I do not know the relationship between speaker power needs and amp wattage power needs.
