From what I've read, under 1% distortion is practically impossible to detect audibly. It doesn't really matter anyway, since the driver distortion of any headphone will be magnitudes higher than that. Other factors matter much more. Also, I don't think there's any headphone that will need that amount of power output that the measurements were taken... even the HE-6 (K1000 I'm not sure about

).

When has it been about real detectability on headfi? Its all about the numbers.

0.04% THD is this quite a lot higher then the 0.0015%@3W into 33R, the Liquid Gold has.

What effect has this on SQ?

Or perhaps the 2.8W is an extreme value that you probably never reach under normal  listening conditions.

Audeze says on there website about their headphones: THD < 1% …..

From cell on flight to LA.

Not an equal comparison. LAu is loafing at 3W. Carbon is just about to hit the rails. THD is pretty good for that condition.

Don't think you'll be listening at that power often.

Better way to view this MHO is that Carbon has a lot of reserve power for such a small linear amp.

In its sweet spot THD is quite low.

In comparison with Senniheiser HDVD8000 listening to last week with a pairs of HD800 cans and i think it hit the seeling to fast.

So are the LC more powerful than the HDVD8000 ?

Do anyone have the spec:

For the Sennheiser HDVD800:
 
Max. output power:  approx. 480 mW @ 1 kHz and 600R load at the XLR-4 output
Power consumption: nom. 9 W (2x 300R headphones connected to the XLR-4 outputs)

For the Sennheiser HDVD800:



Max. output power:  approx. 480 mW @ 1 kHz and 600R load at the XLR-4 output

Power consumption: nom. 9 W (2x 300R headphones connected to the XLR-4 outputs)

So Alex, what are the ouput for the Carbon @ 600Ohms is it equal to the HDVD800 in power spec?

Because you could only listened to medium high volume.

After a million questions, I finally preordered. Looking forward to pair this with the LCD-X!

I think it depends on how much power your headphone needs. 5vrms into the 1x gain will give you close to 5vrms at the output. But from the sounds of it 5V rms x 3 will be more than the max of 12vrms that Dr C was saying was what the LC is designed to run at, so you should not turn the gain dial more than 3/4 of the way up when using the 3x gain mode (assuming my useless math is correct).
 
And assuming the music is recorded or mastered so that it is loud.

Thank you.

Would be very intresting to hear the power difference and SQ performance in reality, btw Carbon vs Crimson ?!

Do we have anyone who have got the oppertunity to tried them out in comparison yet?

So far as I know HD800 are 300 ohms. The Carbon at max power is 17V peak. If I do the RMS power calculation 17 * 17 / (2 * 300) = 481mW continuous power from the balanced output. Does Sennheiser spec the RMS power or the peak power?? There will be much lower power dissipation with HD800s so the Carbon should be happy driving them.

Crimson has more than twice the power.

Thas for your fast anwear and calculation

I thaught when you played with the HDVD800 amp the sound where breaking up and where very doll , and lacked a great of power.

But HDVD800 amp most have like 1,5 watt att 50R also , so it is pretty equal in power with LC , but the LC have a bigger power reservoir (2.8 watt) , so it must be a better amp

 

[Beolab]

Yes i know but in a direct comparison watt are not all on a paper, it would be intresting to here from one whio have tested both of them.

 

[longbowbbs]

I have....The Crimson is clearly more powerful. They are both wonderful. One is transportable the other is a killer desktop device. If I could have only one, it would be the Crimson.

You won't be disappointed

Just ordered one to go with some HE-1000s
