I just started checking out my AD, got a few hours in so far. Still trying to adjust to the lighter bass. I know it is there, but the low end just doesn't seem as full. How do you know if you have a good seal? maybe that is my issue or I just need to adjust since I used He-400's so much.

How much sound leakage/isolation do the hd650 have compared to Hifiman or Audeze headphones. I know it will have leakage, but is it as severe as the others?

Check out the Audinst Hud-mx1. It is a good DAC/AMP combo with a optical output as well. It is really good for this price point.   I am not sure, did you need a optical output or input?

I would say defiantly go for the Mad Dog, if its mostly home use. Though, if you are going to be using for portable use quite often, the Momemtums seem like a better choice. Momemtum has a good build for portable and I beleive it does not need much amping.

What I am wondering is if the ADs are an improved Mad Dog or a completely separate thing? Would a person with ADs ever want to downgrade to Mads?   Bought the Alpha dogs (still waiting) but the more I hear about the Mad Dogs, they seem to match the sound I prefer. 

Has production of November orders started yet, or still in October?

Anyone end up comparing this DAC section to a bifrost/uberfrost yet?

How is the cable on the th600? I had Denon d2000 and the cable was the worst. From all the photos they seem to all share the same cable.

So is production pretty much at the 6week point now?

Ordered my Alpha Dogs. This is is going be hard waiting, but I am sure it will be worth it! Now I just need to decide on the Asgard2 or Lyr with Bitfrost, anyone use these combos with the AD's yet?

Quote: Nice choice. Did you get than $600 open box deal?

They don't get hot or sweaty too much, mabey a little, they are really comfortable. I never used velor before not sure how that is

The Denon AH-D2000 seems like it would be good for you and the music genres you listen to, jack of all trades but it is really good with Hip-hop and Rock type genres.. I dont think those AKG will be good for the music, not sure about the Beyers. It also has synergy with the Asgard. 

Quote: This was my first dac/hp amp so I am not expirienced. I noticed the soundstage open up, more detail the bass seemed cleaner/fuller and added a nice slam to it, made my denon d2000 even better, nothing negative to say about it. The two seem to match up pretty well, other people...

Sounds like I wont be disapointed with the he-500s. I know the denon lineup leaks quite a bit for being closed type, do the hifiman's leak much more? I would assume they do.
