Ha, ha! 152 forum pages of lip smacking! This should be called the HE-560/HE-400i Anticipation Thread.

So this made me ears perk up. Will the new Jerg inspired pads be backward compatible with the HE-400 and HE-500?

 

I wonder how they would improve/affect the sound? If good, I may have to get a pair of the pads.

To expect more from man is to be foolish. Jerg is a man. or a woman i don't know. lol

 

Regardless of all the above I am assured that there will be much revealed about the product that we don't know now and that will be extremely useful.

 

So from impressions of these I will be looking for the areas in the reviews that are skipped, kinda glossed over, or not so deeply expounded on.

ie..

 

" the bass is in balance with the mids with adequate punch to satisfy most audiophiles....blah blah... (not so clear) vs  the bass does have the orthodynamic texture and is even tighter and more controlled than its predecessors yet looses out in impact with less quantity.(clearer) "

 

Like the first days on the job after the interview the flaws don't show up to work the first day.

I disagree with the parts in bold :veryevil::popcorn:

I notice a lot of discussion about needing a full 1W of power to drive HE-400s/500s and a few pages back some were suggesting the same might be required for the 400i/560. I don't get why this much power is needed and would love some explanation to help me understand better.

 

Based on the maths, the HE-500s require about 0.40mW (125mV and 3.25mA) to reach 85dB. Even at 95dB they only require 4mW (400mV and a little over 10mA). It's not as though they have some huge resistance spike in the frequency range so I don't understand the reported hunger for power.

 

Have I (and others - see the Heaphone Power Calculator spreadsheet here on Head-Fi) got the maths wrong or am I missing something?

I believe the extra power is for current? I don't know.

+1, the math and ears don't add up. Is something in the equation or values given by HP manufacturers off or what gives?

You don't need the power.

I believe Dr Fang recommended 1 Watt, over time this morphed into the current required 1-2 Watts myth

1 Watt was never really a requirement only recommended

In my experience the 500 is great out of anything with more than 300Mw

On the Hifiman website they indicate "regular amplifiers" are ok with the HE-500 and HE-400.  Only the HE-4 and HE-6 require >2 watts and that is to reach the loud levels that some people enjoy.  With the HE-560 and HE-400i there is less concern about power.  With that said, I had an amp that put out 2 watts of power and a DAC putting out 2.5V.  I found the listening levels to low with the HE-500 and some high resolution files.  Everything else was fine.

x2.  I was looking for the original power statements and indeed those requires have been removed from the website.

Wow. Thanks for the quick responses confirming the myth factor everyone - I was starting to get worried and can confirm, like many of you, that the HE-500s sound just great out of lower powered amplifiers including good quality portables like the Fiio E12DIY.

 

Of course, headroom, current capabilities and voltage swing all play a part, but if you've got a good quality circuit with few hundred milliwatts to play with and a decent voltage power supply there's no reason that you can't drive the HE headphones to an exceptional level of sound quality and plenty of volume.
