I can't quite get my head around what gain is and what it means. I'm planning to buy an O2 amp with an ODAC built in.
Also, I use a set of Creative T40 Series II desktop speakers and plug my Beyerdynamic DT 990 Pro(250 ohms) into the speakers.
Now, I'm planning to purchase my unit over ebay from a guy in Spain, since I live in Denmark(both countries are within the EU) so there will be no customs fees, import taxes etc.
This guy is buying the parts and putting the unit together himself and he notes that the amp comes with 2.5x & 6.5x gain by default and that he can change this to anything the customer wants.
My question to you clever people is of course: Do I want other gains settings? And does it even matter when the Creative speakers are plugged in between the headphones and the unit? Do I need to throw the speakers out the window and use the unit solely with the headphones?
