Yep.  I just didn't want some of the folks who may be less familiar with amplification to get the idea that it was the fault of the GAIN.  The higher the gain is the more it will show off the flaws (shortcomings, however you want to phrase it) of an amplifier design.

Exactly potterma, with my hpa8 the gain closer to 0 gives a much wider, natural soundstage . However there is no noise raised to 10, just a more saturated soundscape. It also really depends on the music played, modern electronic with that deep base hits through the th900, need little gain. 1974 Bowie and other type bands may need a touch of gain. I'm truly impressed with the hpa8.

Hi, I have an Auralic Taurus mkII and the He 6 sound great on it, however I received a  He-adapter yesterday and connected it to my tube amp (Line Magnetic 216 - 2 x 38w in ultra linear or 2 x 22w in triode) and they sounded even better. I have ordered Q-Cables and will post my impressions after more testing.

I wonder which one is better to driver HE6,between BHA-1 and SPA1.

As I understand you want 5 watts at 50 ohms minimum to power these cans. Hpa8 fostex is 7 and ef6 is at 5, both you listed i believe are at 3.5 and less.

Be carfull putting watts to those headphones
They are wired. You may think it's ok and then it's just not
Above all they need current not just wattage . I would allow much more unless the amp
Is proven by others

Need to careful with watts, even if we are using he-adapter ?

Sorry no not having enough. They really are speakers
Not headphones and not very Efficient either. So not enough to get the right sound is paramount
Resisters can make it lower but if you do not have enough to begin with
It's over. Ok

Currently I am using HE-6 with Lyr and planning to get emotiva upa-200 which has 125 watts / channel (8 ohms; all channels driven).

 

upa-200 was suggested by @preproman, also I will be getting he-adapter, as I do not have any other preamp now, has to use Lyr as one. Is there anything I need to be carefull with this setup

 

Lyr->UPA-200->HEAdapter->HE6

Yes. You need to be careful not to overdrive the Emotiva with the Lyr. You will get massive clipping and even squealing. Test with a cheap set of speakers first, or even better, an oscilloscope if you have one.

Can you please elaborate, I am dump guy when it comes to watts and volts :confused_face:

 

I do not have oscilloscope, but if required I will get one. I had hard experiences with HE-6, both drivers were dead when I got used one (damaged in transit), had to get replacement from Hifiman paying 230$ for it.

 

As I have not ordered UPA-200 still, I have options.

 

Should I look for different amp other than UPA-200, with less watts?

If Lyr as preamp is the problem because of high output signal, then I will not be use it with Lyr. In this case what spec I need to look from an preamp?

I have pair of old Yamaha speakers 8 ohms, if I get UPA-200, what should I be testing for. If speakers performs ok with high vol, should I considers it as safe?

How to use oscilloscope to determine it is safe?

The easiest way to avoid this issue can be explained like this:

 

1) Hook all your gear up, using cheap speakers, ready to play a song with volume at 0%

2) Press Play

3) Slowly turn the volume up

4) Keep turning it up until you notice audible clipping.

5) Back the volume off atleast a notch or two. That is your maximum volume. Never exceed it.

6) Connect headphones and enjoy the music.

Understood, thanks a lot for suggestion. One last questions, how do you classify cheap speakers? If I am testing with speakers, I need to make sure they have similar kind of resistance HE-6 has, otherwise max volume will be wrong from this test.
