My desktop/laptop computer. I can lend a Essence HDACC if I want to, but I'm not sure.
What determine wether its a bad pre or not to pair with a F6? And ofc, I would still need to use the HE-Adapter.
And here are the specs of a F6:
Got my M11 tonight, listening to it with the HE6 balanced right now. The biggest difference with the nfb 10.33 is that the treble is better tamed, don't hear any significant spikes anymore. I'd think that's the R2R DAC working its charm. Otherwise the sound is as amazing as it was, just what I expected. I got the modded version for HE6 (essentially has an extra +6db boost). The unit itself is quite beautiful. I think my amp/DAC search is over...for now.
