I'm not sure how much of a difference it would make, but Mike is using the Bifrost as his DAC. He will be upgrading to the Gungnir, so perhaps going fully balanced
will help out the HE-6. The Lyr could drive the HE-6, however it wasn't ideal. I suspect Mjolnir will do fine (will find out tomorrow hopefully), but what needs to be hammered home
is headphone amps v speaker amps. 8w into 50 ohms is plenty to drive the HE-6, but comparatively to a speaker amp it will suffer in soundstage, details, and overall smoothness.
Those t-amps are good for the HE-6, but as far as how clarity and detail show through compared to Mjolnir...no one's commented.
I've heard a t-amp drive the HE-6 and it almost got the job done, then I heard some monoblocks and that revealed everything that was missing.
Mjolnir will mostly be used for my LCD's and Mad Dog's in mind, however I of course plan to try out the HE-6 just to see how livable that combo would be.
As good as a headphone amp can be with the HE-6 (which can be completely fine) a speaker amp opens up "another world" as far as performance.
The point I'm trying to make is to just try out a "good" speaker amp, pure class A is possible. Compare the two. I'm not saying one is better than the other - although for "me" that is what i've come up with. However, I've tried many amps with the HE-6. Speaker amps and headphone amps. Nothing out did a good class A speaker amp for "me"
