Cool, do it to it as they say!

Also i owned the original Lyr/Bifrost several years ago that I used with the HD800s so sibilent I couldn't listen for any more than 30 to 40 minutes. I gave my brother the amp dac and sold the HD800s. Oh well here i go again!

 

[ezvkm77]

I'd love to see a post with your thoughts on that amp, have a good trip!

@ezvkm77 If you're going single ended you'll get a lot of Gustard H10 recommendations. The H10 drives planars simply superbly. LCD's, HiFiMan's, Ether's and PMx2's get the very most out of the Gustard. You can even opamp roll in the H10 to great effect. Lots of info on opamps over on the H10 thread.
 
I suggest skimming through the first and last 10 pages or so to get a brief idea of what the H10 is and what it's capable of. Look for @stuartmc, he's the cap'n.............there's a nautical theme over there.

Oh ya! And do the Jerg mod!!!!!!

 

[ezvkm77]

I'll do that thanks!

Would someone do me a favor and tell me - instead of me having to search for the answer among all those posts - whether it's generally possible to smoothen the aggressive/energetic treble of the 560 to the point where it becomes a non-factor? I'm thinking mods, EQ, AMPs, DACs...
For example, I was told that the NFB 11 would do the trick, but i'm not convinced.

I have EQ'ed mine down 2 db in the 8-9kHz region. That works perfectly for me. Some have EQ'ed the 6-7khz by 1db as they're sensitive to frequencies in that region.

Easily tamed, just get a parametric EQ, lots of them including a decent one built into JRiver Media Center for instance. You can then play around, get the settings to your taste, save the settings and use them or defeat them as needed.

To get the best results, i would suggest using equal loudness curves to find out your ears sensitivity to sound at different frequencies. Run the test at the link below to identify your hearing curve based on the HE-560s. It will be different with different headphones.

You can use the results in the following manner:
 
1) If for example, the 6kHz region is below the 1khz point by 3 db, eq that region up by 1db at the beginning using the inbuilt or external equalizer you have. Increase as you see fit.
 
2) If the 8kHz is higher than the 1khz point, eq down by 1db to start. Continue till satisfied.
 
Everyone's ears are different. Thus eq curves will generally differ slightly due to ear sensitivity to frequencies being different for everyone.
 
I did the test first, then used Electri-Q (parametric equalizer) to create my ideal hearing curve.

What amp are you using? I had this issue using my Geek Out, when I went to RSA HR-2 (and later to MicroZOTL2) didn't not it any more (maybe some brain burn in, but think the amplification is important in this area).

 

[Uriel41]

Man, thanks for all the swift replies and good suggestions! I'm using my O2 ODAC at the moment and i know it's not ideal. Any recommendations in that area? I'll definitely try the parametric EQing with that link.

The Gustard H10 is an excellent amp for the HE-560s. It's currently available on Massdrop for $300. At that price, its value and performance is simply unmatched. In other word it's an absolute steal. There are only 3 more days till the drop ends. So great timing if you want one.

Too bad it's only a US deal

Good thing i pitched in for Cavallli Audio Liquid Carbon then!!
