Trying to tweak Creek OBH-11...Help please!

I just bought a used OBH-11 and I bought the Elpac regulated PS to go with it. I am very interested in using this a platform for my first DIY project.

I am going to be using this with K701 phones, so I'd prefer a warmer sound, but still retain the sparkly treble(if possible).

Can you guys please help me with which caps and op amps to use? Also, if you could provide any links to purchasing info because I am unexperienced in this area, that would be great!

Try vibration damping too, it can be a cheap & effective way to reduce stridency.

Here is my plan:

 

2x Hovland Musicap 1.0uF 200V in the input path

2x Elna Cerafine 220uF 25V in the output

OPA2134 opamp

 

+ the aforementioned regulated PS

 

I hope the opamp helps to warm up the K701. We shall see...
