Does anyone have any blind tests with the O2 they care to share? If not can anyone conduct them? I would be much more likely to get one if I could actually be shown it does something. Peoples opinions and statements in the hi-fi world are meaningless. Its an industry built on snake oil and BS, but there is some truth in good sound. Plus its the Objective AMP! Make audio objective - Blind tests guys! I swear its like pulling teeth to get any useful information on audio on the internet.
In Voldemorts review of the HD650, he said a dedicated Amp may not be required.
"Generally you need about 2 volts RMS (5.7 volts peak-to-peak) for wide dynamic range music at realistic levels. PC and portable audio gear is typically limited to around 1 volt or less with many managing only about 0.5 volts. So you might need a headphone amp. While the 650 may deserve better, even the $20 FiiO E5 can manage about 1.3 volts which might be enough for many tastes."
I am pretty sure my PC has alot more than 1V, it gets the HD580s ridiculously loud. I usually listen at 25%. And if you listen at reasonable levels always on a decently powered computer, is an dedicated amp really gonna do much?
