Not only that, but he's only looking at a piece of the picture, not the bigger picture. Of course Mr. Pass is correct, but he simply didn't go into the finer details. It's akin to a small/medium/large T-Shirt, and a custom-tailored suit. I'll have to hand it off to Potterma since he will surely have something to say.

Seems to be a lot of disagreement about why many think that speaker amps tend to sound better with the HE-6.  There seems to be more agreement that many people think, for whatever reason, that the HE-6 is not very special on some of the beefier headphone amps but is pretty special on a range of speaker amps.  Or is that controversial also?

It seems so. Let me help you:

 

Ohms Law - I guess you know about it? It translates into this:

The max Voltage of the amp devided by the resistance of the driver equals the amount of Ampere required.

 

In the case of HE-6's resistance (50 Ohms) this means that if for instance the max Voltage of the amp is 12.5V, the max current draw will be 0.25 Ampere. With an extreme power amp* (we're talking 250W @ 8 Ohm) which will deliver a max of 58 Volts, the HE-6 will draw just a little above 1 Ampere. Repeat: slightly above ONE Ampere.

 

Somebody tell me I am wrong here? Please do, if I am mistaken here.

What I do understand is Ohms Law.  What I don't understand is where are you going with this?  You're saying all of this to make what point?

Controversial ... I don't know, but as my post above states, the current draw can't be that huge since it's a 50 Ohm driver. My "super-duper Ampere-delivering" speaker amp isn't giving me a more powerful or more well-bodied sound than the Soloist or Master 6 (with HE-6). Slightly warmer yes, but not better in ways that would be associated with better current reserves.

Read my post carefully again, then.

@LarsHP Another juicy bit is 1%+ distortion figures in regards to power handling of the HE-6. That is where most headphone amps falter compared to speaker amps, among other things. Normally distortion isn't an issue, but at 1%+ it's noticeable and 10% being awful.

That's OK.

I think the 'point' he's trying to make is questioning the use of a speaker amp vs. headphone amp. If you look at the pros/cons of both and prioritize price/performance, speaker amps win overall. It's just a re-cycle of what has already been questioned ad nauseum.

OK OK OK I do not want to be Joe  Pesci  here but...  in some ways we are all mostly correct.  and al though ohms law rules, there are some determining factors effecting the outcome.  as it does see more powerful amps tend lessen the brightness . I make this statement. if you have speakers with a under powered amp. you get the highs but little bass. and this we can all agree yes///????  to be continued...

part two . as for power needed or used lets use something i own as reference and i think others might as well . the audio gd m8 is rated from kingwa,s website as having 7 watts at 40 ohms so from this we can calculate the voltage ,. but the dc resistance of my cans is about 50 and this is resistance as imp can go up or down given any inductance added to the equation to get the impedance . at almost all the way up on the volume control it needs to be before the headphones are loud. this is based on 7 watts at 40 ohms. his new amp is now rated at 9 for the same. i added resistors to mine to achieve about the same watts rating. add this to what i posted and the other people here, and this is why we are all hear trying to find audio nirvana for these headphones. i hope this helps all of us.
and i know we are all trying for the same goals...

It's been my experience that fencing with the non-speaker amp folks is just a waste of time, considering the overwhelming testimonials for the use of quality speaker amps...with most headphones, not just the HE-6 or HE-5LE.

I use, or have used, speaker amps for HD-800, HD 600, AKG 702 and 712, Beyer DT660, DT880, T1 (tubes), exclusively for over a year with STELLAR results. (Read the Speaker Amp thread if you're interested.)

Please, anyone with the "you'll blow your headphone hysteria"-- get real!

In short I disagree:

If the amplifier - speaker or headphone - is able to deliver the needed power (Ampere and Volts) for a certain SPL in dB, then we have "no" distortion (meaning it's not clipping or it's less than 1% THD), because the power rating of amps - both speaker and headphone - is commonly based on 1% THD. So if the amplifier delivers X Watt in Y Ohms, then it's at or less than 1% THD (if we talk about sober measurements).

 

I don't hear ANY distortion with my headphone amps driving the HE-6 - even at earsplitting levels.

 

A headphone amp is designed to drive headphone loads - and HE-6 is such a load in terms of impedance. At 50 or 53 Ohm or whatever it is, you need much, much less Ampere than a speaker at 4 Ohm - less than a 10th actually. 

 

However, we all agree that the HE-6 is extremely low in sensitivty. This means it needs a certain Wattage - yes that word again - to reach a certain undistorted peak or continuous SPL level. This is where the high powered headphone and speaker amps enter of course. But again - because of the impedance of the driver, the huge trafo's and PSU's you find in speaker amps aren't needed in order to deliver the required Amperes, since we are talking much less than one Ampere for the HE-6 to reach 110dB for instance.

Very and thanks . I guess back in the days when I was young at this a speaker amp was all I had if I had any headphones. I have read on another forum about people useing speaker amps and I have a couple of friends too. Good idea and thanks for suggesting it..cheers

I am not sitting on the fence regarding speaker amp with HE-6. I started using my speaker amp with it. As I have reported several times, the speaker amp I have is a 50W class A speaker amp with huge PSU, but it doesn't give the HE-6 more bass or anything else IME.
