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...
Try using OPA 2134 or OPA 2107's all around...these should calm the treble down quite abit...

What if I'm not using the headphone amp in it? Well I will be, but most of the time I'll just be using the DAC.

Still, I should probably find another place for it.

Thanks

If you only want to use the DAC, DC the Hadamp, you might get away with it in that space. The Headamp makes a lot of heat.

You'd have to disconnect the amp or it will heat up even if you don't have it active.

Les - I'm drooling over those GS1000s! I had the 225s at one time... sold them because I wanted to try new things - and never replaced them because I like my 600s and needed a closed can... I've never heard anything better from Grado, but I really think I'd like anything from the RS2 up - like a lot!

Actually the 225's are donor canz. I'm having JMoney Deep Woody's made for them in Cocobolo Rosewood. Also the Padded Lambskin headband. So they should be Killer when I'm done with them. Especially considering i liked them in stock form!

Lol, no. If you aren't getting the sound you like from your headphones, then buying different ones is the sensible thing to do.

Hey, sorry I couldn't find an answer from searching, but, which OPA2604 is the correct one to use for the Zero? There are like 7 from this website

OPA2604 is the original opamp that the Zero comes with.

Opps I meant OPA627. Which one on that list is the correct one?

From a cursory search I gather the OPA627AP is the one with the legs that doesn't require soldering? Am I correct?

Just purchased one of these babies to use with my Ultrasone Pro 900. Any particular op-amp combo I should use?
