I'm pretty excited to have my Mjolnir amp back with me. It sounded amazing with the HD800. While the amp inside my dac is no slouch there's something missing compared to that amp. All things point to the HE-6 and Mjolnir being a good combination and I'm hoping that to be true. I'm not going to have headphone specific amps. I like versatility in my amps and having the ability to sound great with all my headphones with the exception of the AD2k since that is single ended...for now :)
I've only heard the HE-6 at a mini meet but it was quiet enough where I could get some real impressions of them and I really liked them but I also like the HD800 but I guess now I have the best of both worlds. A few weeks ago I thought I would never own the HE-6 but after hearing them and seeing a good deal on them I just couldn't pass. I thought I was done with the HD800 but apparently not. I consider the HE-6 and HD800 the top 2 headphones outside of Stax so I guess the next step if I want to go there would be Stax and thankfully I can't afford that right now.
I heard the HE-6 sounds pretty good with the MJ. However, the HD800 with the MJ is very interesting, I heard this amp has a very aggressive, resolving and transparent style - I'm not sure if the MJ and the HD800 will be a good match, I can imagine the MJ being a great match with the LCD-2.2 and the color it brings to the table - that type of amp like the BHA-1 with the LCDs are just a match made in Head Fi heaven.
