its just my speculation based on FR graph and a close signature to HD700 i try...    I promise to test it in near future.   But it not an HD800 thread, just stop to wash this 1.5K$ phone with paint that getting off...

  But according to you those pair are sounds like 1700 and 5000$ ? :))))     Believe me, I wouldn't pay for them even 300$, I'm using it from time to time, just because my friend can not able to listen to them ... So the price doesn't meter, the price in case of headphone, is the last...

  I use now AK120 and AK100 , via optical, checked with AK240 (sold), have not notice any difference, they gives the same optical output. (At least me and my friends can not notice any significant difference. The optical is preferred by me. A superb liquid and 3D sound. So much better then...

  Ohhh... really ? Can or can not, let me decide, I never say I can judge , I just say that "the FR graph is a starting point", and company who produce a 700$ headphone for professionals and 1500$ for enthusiasts, if the company respects they customers, they must provide a prove of headphone...

  Wide and clear doors opening sound .... I usually made a test using bells, piano, clavier , voices... will try the doors now. This album sounds amazing.   Actually, I also didn't like the Hugo by USB sound... The liquid 3D Hugo signature I only can find via optical input, Coax is also...

  Did you work in AK ?   Very strange... the Hugo specs are much higher then AK380... SNR 140dB in Hugo vs 116dB in AK380 for example... All the speculations about a much (!!!) "wider soundstage" and "greater clarity" in this level of (portable) sound is such a Bu*7*^876...   Just a new...

Never try the Audiorvana... But Amarra is the worst sounding software ever. 100% garbage. Much worse then free Vox and itunes. As you know the eq from ak daps is affecting the digital output. That can be the reason for the difference. The pro eq on ak120 for example, can ruin the sound.

No graphs, no money. Beyer, go and learn from a German hyper-professionals: http://en.leica-camera.com/content/download/124163/1364813/version/6/file/Technical+Data_Leica+Summilux-M_1%2C4_28mm_EN_2.pdf   With no graphs, you sell a pig in a poke.

  Sounds amazing...   such a lively sound... the human speach is so much different then a regular connection... its very mid-forward. With punchy bass and gentle treble.

Thank you! Will check it later. Very interesting...

  The difference could be equal to zero or very little. I think to  be sure, a few people must check it. I talked about EQ difference, the sound signature must be the same. Hugo DAC does all the job.   Again, it was very easy to make my friend to order a new 380 with an amp, he is on the...

  Two Hugo and AK daps owners and they wives.

In blind test 4 of 4 listeners could not find any difference between ak100/ak120+hugo vs 240+hugo. (that why I sold the ak240)   I convinced my friend to get an AK380 + a new AK dedicated amp, so next month could post a true opinions. (the trasport test)   I guess the difference could be...

  I can not be sure for 100%, a friend of mine order it from here... it looks like a legit pait.. http://www.ebay.com/itm/171633965349?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

    Just made a comparison a week ago,,, very dull and boring,  flat sound when compared to MT220, the JVC frz80 (even cheaper) is so much better and involving.

  The old and boring se535 nipples , will never sound like huge sounded MT220 pure fun speakers.

1770 claimd as monitor headphones, So it must sound much better then this fancy, extremly unrealistic "so called" headphones.

Probably, the pioneer is just a re-branding ... :(

Ohh... crap... this is funny.... :) "A modern audiophile mountain"*   [Mod Edit: Please don't post fake graphs. You'd be surprised how fast this would get sent around as fact and mislead people.]                           *it's just a speculation...

You know, Youth, in photo-world, its a standard to provide an MTF graph by manufactures for every new lens... Every new day, every minute of the day, My ears feel different, they are very bad For measurements... You know, even a small amount of good mood and good cognac can became a crappy...

  Sad but true...   And all hopes goes now to DT1770... It's time to get a new studio reference from a solid company...     Beyerdynamics...   Just gives us its FR graph, please!

  Off course I need an amp. Every headphone needs an Amp, and I have one. Will highly recommend it ...

  You are funny, you are probably very smart person, if you're able to express such a stupid statement. It's mutually exclusive.

  It's very subjective. Could you prove it in some technical way ? Maybe you just ruined your hearing using an equalized and abnormal highs ? From my experience , HD600 is extremely good for classical/vocal/opera music
