You are also saying that I refer to graphs and others opinion even though I have demonstrated otherwise. The amps I have and use are extremely good at delivering current - both fast and lots of it, as you should have understood from my previous posts. I will try one last time to explain it.

 

You ask me what amps were used for these measurments, and I don't know that. You probably knew that when you asked me. However, by asking that question you reveal that you haven't understood what I have already said: It takes only 19,69 MILLI-watts to reach 90 dB with the HE-6. I just looked at the numbers again, and found that to produce those 90dB using 19,69mW, it takes 1018mV and using only 0,019mA - that's 0,000019 Ampere. Are you really trying to make me and others at Head-Fi belive that the amps used for these measurments can't deliver these small amounts of current, and that this produces extra treble?

 

To put things in perspective: I have the Balanced amp card for the HM-801 and it delivers 440mW. The HE-6 sounds less bright out of that than via my Master-6 or ZAPsolute, when the Audio-gd Ref 7.1 DAC is used as source. Why? Because the HM-801 has a rolled off treble and the Ref 7.1 has a flat response. In other words (again): Power or current is not the case, but the treble is.

 

I don't find this exchange of viewpoints fruitful since you don't seem to have an open attitude to what I have to offer. So - let's just say goodbye and leave room for others to share what they have on their mind. I certainly don't wan't to discuss this further along these lines.
 

 

 

Good See Ya.  Because you fail to see my point as well.  Again, you bring numbers and specs into the conversation.  The bold text above tells me you go by numbers and numbers only.  Logic does not apply here.  I keep telling you these mean nothing.  If that was the case there will be many amps that would meet those specs, but still fail as a good match for the H-6.  Practical experience and amp rolling plays a bigger part than your specs and numbers.  

 

Enough Said.

 

So I say to you.

 

Fair well.

You simply don't read what I write. You ignore all the other things I have said based on my own experience and gear. The numbers are just support for my points. Hopefully we can end this discussion in a nice way also?

post #7999 of 14887

I understand your points. I just don't agree with most of them

 

I'm Done..  Hope you are as well.biggrin.gif

Don't go Lars , I would love to know how the Master-6 and Conductor compare with the HE-6.

I agree that power and ampere are not the issue but I have a feeling that despite their low impedance the HE-6 craves large voltage swing.

Using 90dB as a benchmark for listening is not really realistic. Transients will easily spike above that. Let's assume an 18dB for headroom and simple calculations. That puts us near 8V and 1.2W, which is quite a bit.

If it was that easy to drive them, then even most portables wouldn't have a problem. I agree, those figures aren't realistic.

We all agree, that for music 20mW is far from enough to drive the HE-6. My point was that the frequency charts aren't skewed because of lacking Watts, Ampere or Volts from the amp in the lab. We don't know which and how powerful or weak they are, but I don't buy the idea that the measurements are wrong because of lacking power.

Hi

Do you know of anyone that would let me listen to their HE-6's in the L.A. or Orange County area?  The factory said they don't have any demos.   I'm new to this & don't want to buy anything expensive as the HiFi MAN HE-6 unless I listen to them first.

 

Could you lead me in the right direction?

 

Thanks,

Bob

Have you by chance heard the Bakoon Amp-11R powering the HE-6 and if so, could you briefly state the differences between the two Bakoon amps.

I have a legitimate non-flaming question to ask regarding driving the HE-6.  Am I correct in assuming that most efficiency measurements/frequency are derived from either single sine wave tones or frequency sweeps?  Perhaps the constantly dynamic and changing waveform of a musical signal presents a greater current demand to amplifiers than the traditional measurement techniques would suggest?  Not trying to further any arguments, just curious if my logic is flawed or not.

The 6s have been accused of being less sensitive than listed. That's been proven wrong. The numbers are science and I will respect that. But between the two, the universe lives differently on this diaphram. Somehow the 6 will use that power very poorly or something because with that power, this headphone has hi fi raised men shaking their heads in disbelief.

Yes, when I had them, I drove them with speaker taps of a mid 90's 100wpc Kenwood A/V receiver.  Sounded quite nice with plenty of power but not the greatest in pure quality, it wasn't one of those monster, old school Kenwood amps.  I'm thinking about getting the HE-6 once again to see how my new Audio-GD SA-31 drives it.  It's rated at 8w @ 50 ohms and uses 4 rather large output transistors commonly only seen on speaker amps, the large flat ones you usually see mounted to a side heatsink.  

 

It's the only Audio-GD headphone product to use them, though their speaker amps use similar style output transistors, just more of them.  Though, I may have to do a small mod to increase the gain.  On high gain it's 10db gain and from a 2v source I'm usually in the upper 50-80% of volume with my AKG K702 65th Anniversary so I might need more gain for the HE-6.
