another help with Grado

Hi to all!
My name is Dani; i've got a Zero Dac with a lt1364 in Dac section and 2 lm4562 for headphones amp.
i've the Grado sr80 and now the trebles are killing my ears and my brains

What can I do to to kill trebles on the headphones amp?
I've read here about of lt1364 in the Amp section and opa627 for dac, but for someone this set up shows again too much bright..

Thank you so much...

Grados are very bright headphones to begin with, so this isn't all that surprising...
Perhaps the moon HDAM from Audio-GD in the DAC section would smooth things out? There's lots of talk about the HDAMs here - have a look around.

Sorry about the horrible quality of the picture, my camera is awful.
That Zero will Over heat most likely. The Headamp makes a lot of heat.

You might be ok if you can aim a fan right in there...

I don't have the link handy, but look up the FrankenZero post in the DIY forum to look into the Capacitor clip which would help a lot. Also find Currawong's post. It will mention the cap clip.

Here is Currawong's Post if you are interested. Introduction to the Zero DAC and Headphone amplifier. - Head-Fi: Covering Headphones, Earphones and Portable Audio

I found the post useful but have not clipped my capacitors yet (Too afraid to)

a quote from that link - makes it sound like a bad idea in this case:

"Note: Myriad felt that after snipping these caps, the sound was too bright for him with his Grados. Grado owners might want to keep this in mind as they are reputably bright headphones.:

I'm doing the FrankenMod also, but won't be clipping this either.

At least i don't think I will.
