HifiMAN HE-6 Planar Magnetic Headphone - Page 868

post #13006 of 19433

I'm very nervous with my setup now after blowing my HE-6 drivers twice. The first time I accidentally turned of my Lampi then turned it back on with the amps still on, there was a soft thud followed by dead quiet. To my frustration while I was at a friends house last week he turned off and on the DAC without any warning and blew a second hp.

Are you guys saying there nothing that can be done to stop this kind of thing from happening besides the precautionary measures you mentioned.

:blink: No matter what other components I use or don't, amps are always the last piece to get turned on and the first piece to get turned off.

May have to send them back to Justin to get rewired to some spades..

Sure, thanks
Got it to work nicely
Connected my MAC directly and HE6 did not blow up smily_headphones1.gif

Appreciate all the feedback. Yes I do have 10 ohm 10 watt resistor's which I will use with the Cayin. Will spend a week with the Rotel first  to get fully familiar with the sound & then try the Cayin. Will report back with my findings.

Same here

Cradon, I've blown a set by the same way. My sympathies. I've just left the rig alone and just use auto on with the amps. The only thing I do is turn the volume down before turning the DAC off. But if you have a nasty spike on turn on, I'd disconnect the cans after turning off.

or just leave the dac on.  my blue circle dac does not have an on/off switch -- it has basically been on for about 5 years with a couple exceptions of being unplugged to move things around the rack.  unless it is a tube dac not sure i see a reason for turning it off

:sigh: I'd offer to stop by but listed airfares are killing me.

IMO is too much and you need to be careful with your volume knob. One time I crossed PMs with Dr. Fang and he recommended to use the adapter to attenuate the signal when amplifiers with 100 watts/ch in 8 ohms or more were used.
Some people disagree with that and are running them with those powerful amplifiers. Nothing will happen a long as you are careful with the volume.
I think the HE-6 can take up to abut 14 watts/ch in 50 ohms or so.

How do you attenuate the signal with the adapter? I was going to use a Bryston 4B-ST that I have lying around when I moved from 7.1 to 5.1. It puts out 250 watts per channel into 8 ohms. I would be using it with a Woo WA 2 as the preamp from my musical fidelity M1dac-a and Squeezebox Touch.

Does attenuating the signal affect the sound?

I would be interested in upgrading from the HE-500 if I did not need to buy a new amp.

The possibility of blowing the drivers does concern me though.

Do some reading up, it uses a resistor network to bring things down, been described at length here in the thread. If you don't want to get the HifiMan adapter (frankly a lot of cash considering the components) then you can cheaply wire up some resistors yourself.   250 WPC is a lot, I'd worry about too high a noise floor with something like that..

post #13017 of 19433

It uses a pair of resistors in parallel and a pair in series but I don't remember which pari does the attenuation. As Xenophon said, do a search herein the thread there is plenty of information about it.

post #13018 of 19433

I used this page as reference, my amp is 125 wpc and used 10w 10 ohm resistor

Step 1-> the leather material at the backside, fold it backwards slowly as seen in PIC 2. Make sure you only see the black cloth on the backside of the Audeze pads 

Step 2-> Use Crazy glue to stick the Audeze plastic rings on black cloth first. Wait for 3 min for glue to take effect

Step 3 -> Remove the Hifiman plastic rings from stock pad

Step 4-> Use Crazy glue to stick HifiMan plastic rings on top of Audeze plastic rings, after this step it should like like Pic 1. Wait for 3 min for glue to take effect

Step 5-> Slowly bring back the leather material on top of both rings as shown in Pic 3

 

once done attach Audeze pad to HE-6 as you do with stock pads.

 

Thanks for the instructions.  I recently re-entered the HE-6 world, and it's nice to try some simple mods.

Your concern is real. Though, it's not something that's kept me up at night. Wait...I AM UP ALL NIGHT anyway! :tongue_smile:

 

Seriously though, I'm running vintage dual mono construction iron benched @ 265/per into 8 Ohms naked sans resistors with my HE-6, so far so good. BUT... I make sure the volume is set to zero before turn-on and plug in the cans moments later. When time to quit I zero the volume and remove the cans and then turn off the receiver.
