Hey guys, I was going to get an O2 amp soon but I ran into a problem:There are different branks of O2 amplifiers.
 
The main one i have seen on head-fi is the JDS Labs model but there are Mayflower and Reverb branded ones too. Are there any differences between these amps?
 
Thanks

Aside from possible variations in parts from different manufacturers, they MUST use exactly the same specifications as the original design otherwise they are NOT allowed to sell it under the 'Objective 2' name.

Aaah............. I see........... 
So i just pick the one that has the ports i like right? 
Is being able to be powered by either two batteries or a AC/AC adapter part of the specs? This is because i really like the amp being able to function both on battery and when plugged in.
 
What about the relay on the second gen O2? How will i know which has a relay or not?
 
Thanks
