Yes, "nothing special" is exactly right, and cheap - £500 delivered in the UK. But the point is that there can be very little that is special about such devices, *other* than what these people talk about, which is audible noise from fans and ironware. That is the only adaptation they have made to suit it to the audio market, and they are honest about it. And they know it does not justify tripling the price.
The basic topology of the purepower aps devices is exactly the same as a conventional double conversion device: this is why they used a UPS manufacturer at the outset. Nothing in their literature explains how -- besides not having noisy fans -- their devices differ from this basic model. And so there is nothing to explain why one should be spending thousands on their version of it. Had they removed fans altogether and added a fuckoff enormous external copper heatsink (say), one might be sympathetic to the high price. But as it is it is hard not to feel this is yet more bullshit in the bullshit-ridden audio world.
Of course the question is always the sound -- and the effects on sound of this device is fine, but I have only had it for a day, and so do not have a view over variations in the quality of power off the wall. And it may be that purepower produces better sound than other double conversion devices. But the vast majority of double conversion devices would never be evaluated against it because they are disqualified at the outset by being too noisy (owing to their cooling). So it is hard for anyone to have a synoptic view.
