Sony claims the card will premium card will produce less electrical noise. I didn't know 1's and 0's were prone to noise haha! 

Thanks! Am I correct in saying this amp doesn't have a balanced 4 pin XLR input?

What exactly is different about these two portable amps? Why would you want one or the other?

Thanks for sharing Dan! It blew me away how much you got out those fostex drivers. I'm glad you've decided to revisit planar magnetic technology. So a different technology is used on your alpha dogs?

Did Dan say his preferred cables to use on the Alpha Primes are the norne vanquish? Could be mistaken.

Looks like I'm checking the classifieds! The M8 looks like a portable tank! :)

This question might of already been brought up but too lazy to look through 66 pages. Can anyone recommend a portable amp that would bring out the Prime's full potential. Now the Alpha Primes are in no mean a portable headphone so to speak but I don't care at all. As long as they don't fall off...

  Wow. Thanks for the update Dan!

I was wondering that question too. If the loss of imaging between a closed and opened is a huge difference. To answer that question now that I think about it, closed headphones have come a long way over the past decade. I'm more concerned about the sound quality than the build quality. Of coarse...

Thanks for replying Boffy! Wow, people can really hear open phones. It makes much more sense now that I think about it to get a closed back headphone. A lot of my music enjoyment is on the go, traveling. Ratio makes a good point that it's a lot better to hear the music than the 12 liter diesel...

Oh, haha, meant the LCD-2. My preferred sound signature is slightly warm, slightly recessed bass. I do not like the HD800's. From what I heard their colder headphones. A little to accurate for my cup of tea. One headphone that I've heard a lot of hype about though is the Alpha Prime's...

*****POLL MISTAKE: MEANT LCD-2 NOT LCD-3!!***** I have a $1000 and my choices at this point are huge. Basically I have 6 headphones that I'm considering buying. The Mr. Speakers Alpha Prime, Beyerdynamic T5p, Beyerdynamic T1, Hifiman HE-560, Fostex TH-900, Audeze lcd-2. I would prefer open...

Haha, that's what he's doing duh! You think the Alpha Prime is a lot better than the Alpha Dog. Is it a right away notice the difference or subtle? From what I'm hearing people didn't think it could get any better and it just did. 

What does adjusting the risers negatively do?

Thanks Matt! haha, I think I'm going to spend an extra $400 :) It'd be interesting to do a comparison of some of the other high end headphones. What I'm looking for is the most opened sounded closed headphones. I think the alpha primes are definitely on top of the list. Another ones the...
