I've never been interested in DAPs, because I tend to listen to want "semi-mobile" in terms of portability. In other words, a DAP to me seems like something that is really geared toward "on the go" listening, if that is your primary means of listening to music (maybe why DAPs are so often paired with IEMs). But for me, I like big bulky headphones and sitting down to listen to music, so I'm fine (and prefer) to use my laptop. A laptop is still more portable than a desktop, so I don't want a DAC/amp that needs to plug into the wall. That's what makes something like the Q7 so appealing to me, because though it is big and powerful like a desktop amp (with the exception of the highest gain setting needing wall power to work), it's still portable enough that if I wanted to take my laptop to another room or on vacation, I could take the Q7 with me.
What I want to know is how the G5 holds up against the Gryphon and the Q7.
@ljnew said that the G5 sounds better than the Gryphon. I guess I will have to test it out. If I like the G5, there may be no reason to go for the Q7 if I don't need the extra features it has (for me it's mainly going to be about sound quality above anything else).
