Unlike other online units the AG1500 is extremely quiet making it suitable for where high quality power is required but without the noise, and unlike other systems the bypass is disabled by default ensuring that raw mains power never reaches your equipment, only clean pure power at all times.

 
Ok, this is Australian version of PP, a commercial double-conversion UPS that they accommodated for audio use. Looks good, I wish they put some audio credentials in there to show off that they are capable to deal with audio objectives.
 
One comment that I would like to make: the fact that they disabled bypass is not a huge accomplishment but rather a stupidity in my view. 1.5kW is very low power and it is very frequently a playback would suck more in peak. So with bypass not being in picture what the unit does then? 1500W is 6.8A at 220V. Any powerful SS amp, or start up saturation of chokes of a tube SET will blow 6.8A with easy. So, what do they do then? Fire a fuse or flow the output transistors? OK.  According to them to feed the load with a few periods of high infiltrated high current is bad but to turn unit off what it demands more current is good? Well, to me it is not smart and juts an indication that they do not have, perhaps yet, any practical experience with real world of playback systems.
