Amps that can drive the HiFiMan HE-6 planar headphones - Page 9

post #121 of 3116

I'm using a pair of 10-ohm inline attenuators out of my tube stage into my speaker amp, then running plain old speaker tap adapter cables. That HE adapter makes me curious though.

How exactly do you set up the resistor without soldering?

You can bend/wrap the leads around the speaker terminals of your speaker amp/receiver with the wires from your headphone then tighten the screw.

BTW this is a big wirewound resistor, its 1.25 inch long and each lead is about 1.5 inch long on each side.

I see how it physically goes now, just do you have one for each channel or, if not which posts do you wrap it around?

I think you need to add Ray Samuels SR-71B to the list of amps that can drive the HE-6. Note only in balanced mode though:

One per channel, wrap each end on the positive and negative (red and black) of the amp speaker terminals.

Add the Liquid Fire headphone amp to this list, its a SE amp but as well balanced as any balanced headphone amp.

 

It is not a real power house like some of you speaker amps, so expect to turn the volume pot up in the range of 12 to 3, but imo it really does a great job powering the HE6. Plus many other high end headphones.

 

If you get a chance, do yourself a favor and try the Liquid Fire.

LF is a hybrid isn't it? Is it mosfet or opamp?

post #129 of 3116

Grace m902 and m903 work well with the HE-6.

 

For "portable options" the discontinued TTVJ Millet Hybrid Portable works well (but not optimal).

 

Also, the new Balanced Amp Module for the HifiMan HM-801 has enough power (only just) for the HE-6.

Mosfet Output Stage Biased at 100mA to Run Class A Most of the Time.

 

Yes it is a Hybrid.

Ed check out the HDMI upgrade for the Realiser, I am now bypassing my BDP-95 DAC stage (still has bass problems) via HDMI to my Realiser and then out to my W4S DAC via toslink,.no more bass problems.

Got my Tung Sol 6550s today for my ARC D70. Biasing them right now.

 

This is why nobody likes to bias a D70 themselves.

Just DMM?  I thought more involved gears are required.  tongue.gif

 

Thanks for mentioning using paralleled resistor to reduce the load impedance for using tube amp with HE-6.  Now tube amp has returned to my radar scope.  biggrin.gif   From what I read, some mentioned that D70 is difficult to service or work on; small fail may results quite damage.  Is it so?

Just one DMM, I have those other cheap DMMs just to monitor for changes but I set the bias using a Fluke 89 IV.

I have not a problem with mine. I replaced the two big caps and another cap because of their age. It uses 5 6550s which are plentiful

today from Russia or China. NOS are expensive though. ARC still services them. You can call them for questions and they are very happy

to answer all your questions. ARC still services all the equipment that they ever made from the '70s til now, amazing. I don't know of any

audio company that can do that.

 

BTW I asked them if they have a black faceplate for a D70, they only have silver in their inventory, this is a 27 year old amp and they still

have some faceplates for it?

So I bought this amp from Parts Express, a refurbished Dayton Audio DTA-100 Class-T 50wpc @ 8ohms for $49.90 plus shipping.

 

After I received it, it looked, well, unimpressive. So I let it sit for a week or so on my desk since it arrived. Tonight I fired it up. Plugged the 6 in its hp in. Nice.

Its a warm sounding amp. If you feel that your 6 is bright this is the amp for you. I've got the vol at max through the hp out.

 

So I let it play for an hour or two. Then I listen again. Not bad. I need to try its speaker out.

 

If you are looking for an amp for your 6 that won't mug your wallet, won't make your ears bleed or fatigue 'em, this amp, IMO fits the bill.

 

 

P.S.:  This amp is very musical, it just let me enjoy listening to music instead of dissecting it. Isn't it what its all about?
