HA2 is discontinued. Why do you want it when there is a newer better version available? Personally, I want just an amp and the Fiio A5 fits the bill perfectly.
Why are we voting about the old model? I'd rather have the new upgraded HA-2 SE model (Should be about the same money) the old had some flaws that are fixed now.
