Now fully five years after the original PP2000 was in my system, then subsequently stopped working and was sent back for repairs to the manufacturer. An unfortunate series of events involving the Chinese subcontractor resulted in the company contracting severely, and my original unit was lost. Numerous excuses were made, but eventually the APS company made it back on their feet. Almost beyond belief after such a long time, and thanks to those here who encouraged APS to "do the right thing" and send me a replacement unit; finally it has arrived! I waited to report on this until the unit was actually physically in my possession... But now it is here. APS sent me a PP3000 Plus unit including the Power Pack and Furutech FPX-R receptacles. After plugging it in and letting it settle for a few days, I have been listening to it this weekend. The sound is as I remember it. It is frankly impossible to make a direct comparison to the PP2000 as it has been such a long time, but all my original remarks apply. The only thing missing is the buzzing hum which plagued my first unit. This unit is absolutely silent in operation, leading perhaps credence to my original suspicion that the original buzzing was due to a manufacturing defect. Now it is totally silent and the Sound is coming through gloriously again. More commentary to come in a while... Worth the wait.

Power Inspired's AG1500 AC ReGenerator is a true online double conversion system providing the highest degrees of power protection, with a stable unwavering high quality power waveform for sensitive and critical loads.

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.

The AG1500 has a manual variable speed fan which allows the user to turn the fan speed to minimum when the unit will be used for only momentary bursts of power so as to minimise any audible distractions.

For UPS support, battery pack B2U-96-9 can be added, although not required for AC ReGeneration and power conditioning.

This item is fitted with a AUSTRALIAN 15A Socket Outlet

The audio product is peripheral to their main business and it is essentially the same as their standard double conversion ups. They say they have done more than change the fans to quiet, but they are short on specifics. Then again the markup is much smaller than for PP, and they are clearly well made machines, or at least mine was when I bought it in april 2013. In the interim they seem to have noticed they are underselling it, and have increased the price from £500 to £700.

Post #: 580 Post ID: 14729 Reply to: 14523 OK, I have moved my motor-generator to the backward in a cozy location under the deck, wrapped it in tarp and left it there in “preserved” mode. Sometime in future I will return to this idea
