I tried the O2 Objective because of all the hype and was totally disappointed. I mean it was technically good for the price. But it was so dry and unmusical to me.
So I'm cautious at this point. But it's hard not to get sucked in. I respect Purrin and his ears but I also know his taste differ than mine. So have to take that into consideration too.
Also take into consideration that I too was highly unimpressed with the O2. And I don't think the O2 is good for the price either. Maybe $49. The O2 is currently used as a measurement amplifier, which is what it should be used for, not for listening.
