Will UPS improve sound quality?

I highly recommend getting a large UPS backup with surge protection.

Mine 650 VA 360 watts.

Surge Protection is just an isolation transformer plugged to the mains.

Backup is a Lithium battery that lasts a few hours for laptop etc.

The main improvement seems to be the isolation transformer.

Running the DAC & headfi amp off the battery alone doesn't add much but the surge protected outlets (running off transformer secondary) do.
Big increase in bass slam and clarity, drop in "electronic hash", and speaker amplifier runs much cooler.

This could be due to mains being cleaned of noise and the heavy lifting is done by the UPS leaving the amp ps with less work and thus less radiated heat.

An $80 80 EUR upgrade that makes your system sound more 'audiophile'.

Plugging speaker amplifier into mains the drop in SQ is immediate.

Playing DAC & headfi ampfi alone into headphones also sounds great when plugged into UPS with speaker amp off. Noticeable SQ improvement.

Current speaker amp is only 15 watts so this might not work with your 1000watt monoblocks.

Definitely will work with any DAC headfi amp combo.

It just sounds much better.

I started using UPS systems around 1995, having been programming desktop computers since 1982. Back then, UPS units were quite expensive, making me hesitant to invest in them. Fortunately, my area doesn't frequently experience noticeable power disruptions. However, after implementing UPS, I observed a significant reduction in "mystery crashes," especially when programming, as older computer systems could easily crash due to minor errors.

Despite the stable AC power in my area, I realized that even minor, unnoticed power fluctuations could affect system stability. Using a UPS contributed to reducing such issues. In my experience, mid-priced UPS units typically last about 5 to 6 years before they either suffer from electronic faults or natural battery wear. While high-end UPS devices might have a longer lifespan, the ones I could afford were essentially consumables.

Over the years, I've noticed that UPS units often stop working due to flaky electronics or battery degradation. Earlier, I attempted to replace batteries for about $100, but the UPS would soon fail due to electronic issues. Manufacturers continuously update battery specifications, making it challenging to reuse batteries from old UPS models in new ones.

After a few unsuccessful repairs, I decided it was more cost-effective to replace the entire UPS unit if it started showing battery issues after four or five years. Rather than investing in a new battery for an aging UPS that might fail, replacing the whole unit seemed a more sensible approach in the long term.
