Those who know everything about how things sound from reading the spec's and measurements and how you can't hear any difference etc. etc. Well, I stay clear of the science forum for that very reason tongue.gif

It's certainly hard to judge sound in terms of a percentage, but I think definitely the biggest improvement in the HE-6 is the soundstage and spacing. 

 

If you want some serious placebo, you should read over the HE-500 thread. It makes my head hurt sometimes to read posts in there.

Looks like I am in the second group to ship, late August. I'll have to find another opportunity to try the HE6 with it, I won't have it in time for the California Audio show. I do hope to compare the HE6 and HE500 side by side though.

No impedance stated means we don't have a clue. It could be in 8 Ohms (f.i. Burson Audio states their 4W in 8 Ohms for the Soloist). In that case 1.5W isn't that impressive (especially compared to a 50 Ohm load).

Agreed.  Here's what I've got, from Centrance's website:

 

 

Output Power

1.5W (total), drives 16...600 Ohm headphones

 

Max Output level*

+13.5dBV (32 Ohms load) (still verifying)

   

+18.6dBV (300 Ohms load) (still verifying)

   

+19.0dBV (600 Ohms load) (still verifying)

 

My EE is so old and rusty, I don't have the interest right now to do the conversion for 13.5dBV to something I can understand, such as current, voltage, or better, power in watts.  Anyone feel like helping out?

Translate into

32 Ohm : ~4.7Vrms - 700mW
300 Ohm: ~8.5Vrms - 241mW
600 Ohm: ~8.9Vrms - 132mW

Thanks khaine.
700mW in 32 Ohm probably implies (since these figures will change in different loads and thus can't be calculated) that the amp will give about 500mW into 50 Ohms.

tongue_smile.gif While everyone is doing ice-cream & math on a beautiful summer day, I've a question. And I know it's been asked and answered. Just like I know it's buried d-e-e-p inside this thread... multiple rolleyes.gifplaces. But:

 

If I tie a tube amp rated 8W @ spkr to a vintage receiver's pre-amp, then plug-in the HE-6 through the receiver's headphone jack @ 120 Ohms, what output would the cans see... how many watts?

I wouldn't use the WA5 as a preamp to your Sansui rolleyes.gif.

The output the cans see will depends on the volume knob of both the WA5 or the Sansui

Um... we're looking at it the other way: Sansui preamp > WA5 monos. Hope this adds clarity.

Wording isn't clear.

 

source to sansui to woo to he-6

 

or

 

source to woo to sansui to he-6?

 

I hope you mean the first, because the second is boom :P

DAC>Sansui Aux>Sansui Preamp Out>WA5 with listening done through Sansui Headphone Out. WA5 monos have only Speaker Out, not Headphone Out. 

 

To be clear, I could always get the WA5 stereo with the K1K Output for the HE-6 (8W @ 120 Ohms). What I'm trying to determine is whether the 8W @ 8 Ohms will be enough for the HE-6.

Then it's stil the wattage of the Sansui, but reduced (on whatever resistor value that the headphone out have).
post #9163 of 14887
The problem using a tube amp of 8W is you need the HE-adapter or the like to avoid destroying your power amp. With a solid state amp you can plug the HE-6 in and it will take whatever juice it has. With tube amps the resistor will get most of it, not the headphone. This means you need a quite powerful tube amp while lower wattage SS amps will do because they don't need the resistor.

Thanks for weighing-in, mates. Back to the Lab I go... scheming and dreaming.

That is really just DAC > Sansui, the Woo isn't relevant.
