drolling at a GMB but im scared to spend loads of money on a DAC only to see something better sounding and better priced be released two years later.. currently rocking the modi 2u > Ragnarok > HE-400i.. haha
The good thing is Gungnir is upgradeable. That's one reason why I bought it. You can buy Gungnir DS first and upgrade later when you want.
But again DACs have lower disminishing return than amps, IMO so settling with Gungnir is probably the right choice for me.
