Hey there, before i start i would just like to say that i've been on this site for virtually 24 hours straight for advice and i'm only doing this as a last resort. as the title says i need an amp/dac combo as i do not want to start fiddling with separate units and tubes etc. I will be listening out of either my macbook pro and dell desktop with stock soundcard mainly. I feel like my headphones aren't performing as well as they can and i know since they are 250ohm they definately need more power.
 
The main contenders are
1) Fiio E7+E9 combo 
2) Ibasso D4 
3) Aune mini USB DAC
4) Zero dac/amp
5) Travagan Green or White
6) Audio Gd Sparrow
7) Audio Gd NFB-12 (cannot afford the FUN)
8) Fubar III mark II
9) Octovart 01
10) Yulong dah1 mark II
 
I know it seems like a lot of choice but i'm thinking hard about options 1 and 2. I am just not sure about how they sound with my beyerdynamic and that's why i need help. Thanks
 
Ps. my budget is anything up to 200 pounds which is about 325 dollars.
 

Anyone have any advice to give?

anyone? please help

I can't say much about sound quality and synergy, as I've never heard the Beyer DT150, but I can say that the E7/E9 combo and the Audio-gd NFB-12 will both easily drive 250 ohm headphones.

Thanks, they are both in the front running, on the nfb-12 thread now..50 more pages 

I think i am going to order the nfb-12 and order the e7/e9 to compare when it gets here. The only problem is returning  the nfb-12 if it turns out i prefer the fiio. Any other input in the 200-300 dollar range?? Help would be appreciated
