Post Subject: Don´t know if typical but well known .Posted by joaco on: 1/30/2011

Romy , I don´t think this is a typical ups unit , but a little more advanced than a typical ups . I think typical UPS does not have double-conversion , at least here in Chile . Note that Pure Power claims "via double conversion technology ..." in somewhere . But yes , it is an online UPS with double conversion . Sadly I don´t have a scope now and yes nobody knows how that 10% is related to sound . It is hard to describe every change because they make the whole music sound different . I said "it just sound much more corrrect now" and in terms of sound I think the mid-bass now has come alive , I could not detect this mid-bass before I do not know why but I suspect was the distortion of the bass because mid-bass is very delicate to show up in some styles , but this change has bring articulation to the rest of the notes , also harsh fundamentals and harsh harmonics are gone , I thought the harsh sound was exclusive responsability of the crossover that is very old , and my room acoustics. but now Im starting to think different . The bass has become a little shy but tighter and it makes space for a clean mid-bass . Voices seems to be more real , and highs seems to extense more , but in a delicate way . Also harmonics decay in a different way than before , I think more slowly , in summary is that for shure it makes a good upgrade in my system , not the type of upgrade that suprise you at the first time but leaves you deaf in 3 hours . But a change that I like to keep . This is just like you are experimenting with pp2000 my point of view , but I would really like to see this unit adapted for audio use .
regards .
