I can vouch for the Atrio M5. I've had mine for less than a week now, and they are just awesome. They are in that category of 'miles ahead of the Vibes'. I bought a pre-release pair directly from their site. If I remember correctly from the site, the retail once released officially will be $199. I think they're a bargain at that. They are just smooth and refined, with amazingly accurate but deep bass (which is a must for me). Do some searching for the atrio's and see what a few others are saying. I don't think you can go wrong with them though.
