| 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. |
