Amps that can drive the HiFiMan HE-6 planar headphones - Page 162

post #2416 of 3211
Ok was it close ?? 9 ohms ?
post #2417 of 3211
Really 7.8. Ohms and didient I say about 8 ohms
Really stop waisting my time. And the he 6 cans vary from 45 to 68 ohms too

Yep, this ^^^

The HE-6 really opens up when properly driven, which is an entirely different beast than merely attaining adequate volume.

Thanks. Sometimes the people who post Mision formation just gets to me

I doubt very many amplifiers are even going to care... If you have some amp that is extremely finicky about the load it drives then, maybe it makes a difference... For the majority of amplifiers out there, they don't care about that little difference in the load.  

 

Which is not to say it won't change the ultimate output power of the amplifier, but you're driving headphones, so ... It doesn't matter.

 

If you are that concerned about it, find a resistor combination that makes YOU happy....

Really?  Got a link?  I'd really love to butt into that conversation!

Page 245 of the he-6 thread. It's was an early discussion about using resistors for transformer coupled tube amps. One even went as far as saying it reduced the amps output to 20%. What's so bad about that is, everyone bought in and even convince some not to even use their amps.

 

Well here's a link to the discussion.

Relax. If I understood you correctly it would be closer to 12ohms, but nevermind.

If the following is correct, they might just be right:

Anybody tried using Naim speaker amps for their HE-6? Some of the small older Naims look so nice and Naim is known for their snappiness and ultra fast performance - and they know their PSUs =)

Well I will chime in and say, based on Rob's calculator, it would be close to 12 ohms and not 8. So maybe his calculator is off? I don't really know. As far as the other part about the resistors absorbing 80% of the wattage, I'm not too sure about. So right now there are two hugely conflicting camps on that. But I will say that when the resistors are in place on my mac, I get the same volume I was getting without the resistors in place. So as for that part of the equation, I really don't know.

 

I will go back and test them on my tube amp and see if there's a difference. I'll have to check the resistors to. They are only 10w resistors so maybe the 200wpc mac was way too much for them.:D

post #2426 of 3211
Ok. A 10 ohm and a 2 ohm in series
Makes 12 ohms across the speaker terminals
Now you put the 50 ohm across the 2 ohm
It gives attenuation for headphones and lowers noise floor
However it gives ABOUT 10 ohms load on the amp
Sorry I was eating and not paying full attention

Now let me explain something else all volume controls
Effect the overall sound as does most amps needing
To expel a certain amount of energy to sound better

So by doing what I said you accomplish
All three items.

Now don't do what I said I am fine with this
I am just explaining to you guys what will give
The best sound and what is safe for the headphones too

Hope this helps

The part in bold could have been left out. No need to get defensive, it's not that big of a deal. No one said it wrong to do what you said. I was just pointing out Rob's calculator did equal out to nearly 12 ohms, you were the one who got an attitude when someone else said according to his calculator it didn't equal 8 ohms like you originally said. I even went as far as asking if his calculator was wrong giving you the benefit of the doubt you could have been correct. So I think it's best to move on from this whole discussion at this point.

I have a resistor box whwre I can bypass the parallel resistors (8 ohm) and the series resistors (50 ohm). Engaging or bypassing the parallel resistors does not affect the volume of my hybrid amp or the lower power 300 b amp. I do not leave them off with the tube amp but I have switched it on and off. The series resistors make a very obvious impact on volume.
post #2429 of 3211

Yeah, given my own experience so far, I would have to say those guys in the other thread must be mistaken. On my gear the resistors definitely doesn't soak up 80% of the wattage. And if it did at all, then I guess there would be no need for the series resistors.

RELAX. lol. Testy are we ?
