Review: Hifiman HE-6/EF-6: An Elite Headphone System, Under One Roof - Page 15

post #211 of 256

Listening with the LCD-3s now.  I like what I'm hearing.  Simply put, this amps has what it takes to drive Orthos.  My HD800s are out getting re cable.  That will be a interesting challenge for the EF-6.

Pure speculation on my part but I bet the EF does very well on the T-1. I wonder how the 800s do? The EF is less treble strident than the GS-X on the HE-6, I actually liked the EF a bit more. This was just a casual and brief listen.

I doubt it was designed with the load of a K701 in mind, so I'm not sure how relevant that info is to the amp's primary capacity, driving the HE-6, which is quite a different beast.

 

The loads presented by the 701 and the HE-6s are gonna be pretty similar actually, the impedances are very close across the entire range. The difference being that the HE-6s requires significantly more power, which would only cause distortion to go up further most likely. though i guess more measurements would be required. Maybe we can keep our fingers crossed that tyll will get around to testing the EF-6

 

 

The K701 can take quite a bit of power also, more than most headphones this side of the HE series. I remember when I had the K701 and the HE5 next to each other out of the EF5, and the K701 was very close to the HE5 on the dial.

Just for kicks, I had the K7 (65 anni's) here and put them on my HE-6 amps (125w monoblocks) and they were a different beast. Plenty of bass and very assertive. I was really surprised with them. I had the 701s for 6 years on a Singlepower Extreme (platinum) and never heard them sound like that.

Hi Preproman,

 

I have the EF6 and it runs very well indeed with LCD3, HD800 and of course HE-6.

 

I particularly want to say that compared to some other amps I used especially with the LCD3 which does not do treble as well as say HE6, the LCD3 sounded very good and very much better (-clear, wider soundstage, well separated and good bass : jazz especially) with this Hifiman amp. I also have the good BUDA but EF-6 is significantly better paired with this headphone (rather vice versa) and much more powerful. I just wish EF-6 was not a 10kg block, and had the nice BUDA portability specs! I consider the EF6 goodish value for $ given the alternatives at present...though there are also other amps that seasoned headfiers have also reccd (I have not heard yet...).

 

One gripe: I wish the volume control on EF6 ran smoother as I often like the volume "inbetween" the clicks....

Yes - I agree 100% about that big ole volume knob and the attenuator.  I have other amps the use the Gold Point and DACT attenuators.  With the EF-6 I get static between clicks.  With the others I get nothing at all silence.  

 

There's no way the EF-6 could be made to be a portable amp.  It needs the big transformers to provide all the current the HE-6 likes.  I have not heard the BUDA.  I think a lot of the false current measurements was done on this amp.  I still say that amp did the HE-6 no justice at all.

anyone tried t1 or hd800 on the ef6? Is it any good with these headphones?

With a gain factor close to that of power amps I'd look for something more optimized for those (efficient) headphones.

I have both and both sound excellent with the EF-6....the LCD-3 also sound great....of the headphones I have the only one I have some problem with is the TH900 and only because of the limited play on the volume knob....IMO all headphones like as much power as they can stand....

They won't get a shred more power than the limit you set through the volume control but all that unused extra gain brings noise (not necessarily audible with such high-impedance headphones) and distortion with it.

Average power those headphones need for comfortable (and hearing-damage free!) listening is below 0.001 W.

never had a noise/distortion  problem....

If you had to pick between the EF6 and BHA 1 for LCD3 and HD800 which would you go for?

EF-6 for both

Thanks man, I have been trying to find the answer to that question for a while now. Most people had not heard both headphones with that amp. Have you got any pics of your rig?
