Currently I have Fiio E6 amp. I tried to use it with recently bought K612.
But it does not produce enough volume to my liking. I use a PC and on-board audio isn't the greatest.
So I want recommendation on amp(+ dac is advantage) which could drive K612 well.
Current choices are SMSL M2 or Fiio Q1.
 
My questions are,
1. Does M2 is significant upgrade over Q1 to sacrifice portability?
2. Are there any other amp that I should look for?

You might consider getting a Sound Blaster Z sound card, should offer a noticeable improvement in the DAC function.
(DAC - Digital to Analog Converter).
And the SB-Z does come with an amplifier more powerful the the E6.

I live in Sri Lanka, small south asia country. So most of product aren't available unless I ordered from Aliexpress or eBay.
So any place I can find Sound Blaster Z is beyond $100. Asus Xonar DGX is available locally. Does it has enough
power to drive K612? My main problem is whether Fiio Q1 will be powerful enough to drive K612.
