That depends...
As much as I hate it when those who don't know firsthand respond, I guess it's my turn.
It would probably help those who DO know to help you if you spelled out the following:
a) What kind of sound are you looking for? Clean? Warm & tubey? Kinda gritty? All sparkly?
b) What are you going to be plugging into it, and where does it go from there? sm57-pre-SBLive-N-tracks?
Neumann U67-pre-Apogee converters-ProTools? (doubtful)
c) What kind of music is it going to be used for? Acoustic jazz? Death-metal? Smooth soul? Neo-punk? Male, female, choir?
You will find those who love and hate all 3 of your choices. Ultimately it will be up to your preference.
If you look around in the other preamp threads here, you'll find plenty of opinions.
To summarize what I've seen so far:
Those who have the Audio Buddy seem to love it, describing it as super-clean, cleaner than pre's costing much more, and an absolute steal at the price. However, there seems to be an issue with the voltage of the phantom power being less than the stated 48v. If your using a dynamic that doesn't need phantom, then it's a non-issue. If you've got an expensive condensor, buy it from a place that you can return it if you're unhappy with the sound. (Good advice for any gear).
The ART camp is divided. Almost all say it's not what you want for clean, but some like it's particular flavor, others do not. Many, if not most, say it's fairly noisy.
The Presonus people seem to generally like it, but I can't really remember the particulars. Sorry. Do a search for "Blue Tube".
Anyway, sorry to ramble, especially when I didn't have anything really to contribute. But if you let people know what your going to use it with and for, they'll be able to help you. Great bunch of people here.
