Your meter pic does a good job of emphasizing that, yes, you do want an amp with some oomph!

 

Thanks for the Carver data point.  I can't imagine how loud 20V would be with the HE-6.  That's remarkable.

BTW... I understand Carver produced some "amazing" equipment in the past (pun intended - I'm just kidding around)

While we are on the topic of watts, volts, ohms, etc., I thought I'd pass along a tool I stumbled upon recently - http://www.rapidtables.com/calc/electric/watt-volt-amp-calculator.htm.

It's useful for performing some of the calculations that have been discussed here.  For example, to calculate watts produced you can enter 20V as a target output value and 50 ohms as the load (for the HE-6) and it will return a value of 8 watts, or to calculate output voltage for a particular amp (ie. 50wpc@8 ohms), it will returns a value of 20V.  I really found it to be a handy tool.  I hope others find it useful as well.

Haha all great idea's - I am sure i will come up with something :P

 

Any recommendations? will have EF-6 and Auralic Taurus at my disposal to try.. but what is a worth step up?

I think most of us HE-6 diehards are running either First Watt, Krell, and serious tube amps. Speaker amps of course :)

Sorry, I don't get the pun... I can be a little dense, sometimes...  I have been impressed by some of the Carver equipment.  My M-200t is rate 120 Watts into 8 ohms, but I've seen it deliver 400 peak watts into 4 ohms!  That's 40 volts peak into 4 ohms.... Never have seen it clip.  The power supply section is its weak link.  The high bias rail is up above 50 V, so I suspect it would swing 45 volts or more before running into voltage clipping.

 

That's a pretty handy calculator.  I'm sure many folks will find it quite useful.  Thanks for the link!

Look like my Pioneer SX650. i am going to set that up again upstairs and use it with the HE6 in the second system when I want to listen upstairs in my the office.. I would like to find an nice SX950 for that room

How many like the HE6 with the pleather pads they came with?

I swapped them with stock velours, like the sound better.  Not saying the pleathers are  bad but the pads are obviously not HifiMan's forte i.m.o.

Can anyone explain why people think you need a very high wattage amplifier for the HE-6? The innerfidelity chart claims that with a mere 19.7 - mW of power, you can get the HE-6 to produce 90 db. The relatively weak Objective 2 amplifier can easily produce much much more than that, producing 88 mW even at 600 ohms (and the HE-6 has much less than 600 ohms of impedance). To be fair, innerfidelity claims that you need a mere 0.16 mW to drive the HD800 to 90 db, so clearly the HE-6 is more power hungry than your average headphone. But I don't know if it's so power hungry that a basic amp can't drive it.

 

I ask because I'm thinking of buying an HE-6 used to add to my collection (I like bright headphones), but I want to make sure I won't have any power issues. I have an O2 amplifier. People who told me the HD800 was hard to drive were dead wrong, it can be driven easily with the amount of power produced by your average laptop jack. Just want to see what the truth is with the HE-6.

OK, so we meet again but I'm relieved to see that in this thread you at least believe you'll need an amp, certainly with the HE-6.  The O2 (abstraction made of its issues) will most definitely NOT drive these.  Tried it once, just for giggles and it does not work, not even on high gain 9where you'll immediately drive it into clipping, btw).  Other people can explain in greater detail why you'll need some serious power to get the best out of the 6 but trust me, you do.  

 

To me, the HE-6 is def. not overly bright.  Sometimes a tinge in the treble but if they sound thin, bright, brittle, no bass...that's because you need a powerful amp.

ok please link me to an amplifier that clearly has enough power for this headphone and I will do a comparison of that amplifier's watt output versus the object 2.

The HE6 need power for headroom. I have the WA5 and use the XLR which goes into the 10W speaker amp and it works fine. The Meir Classic is about 7.5 watts and will collapse wen it trie to drive symphonic recordings. The O2 will nto play them at all at any satisfactory level. they are a 83DB inefficient power hog. mThe GSX MK11 does not drive them to their potential. You need a high current amp with good dynamic range.

When people say the HD800 is hard to drive they are talking about synergy not about power. Sure, you can drive the HE-6 with your O thingie, and it will make noise. If you want it to sound good you need some power. If you want it to sound its best you need lots of GOOD power.

That's like a speaker amplifier. Maybe I should just plug the HE-6 to my receiver's speaker output lol.
