Actually, the CA2 and CA9 position have the most to do with preserving bass from the basic input signal/source. It's a question of keeping all there is, or taking some away. This can happen with the wrong bypass cap at CA9 (don't use Vitamin Q's, there, for instance), or if CA2 is too small (<1000uf). Either the ES 1000uf 16V or the Elna RFS Silmic II at 1000uf and one of the voltage ratings listed in the previous post is best. For CA9, you should just use Wima MKP10's.
As far as bass at CA7, it's strictly controlled by the RC-circuit cutoff frequency formed with CA7, RB14, and the impedance of the headphones. 1000uf should take care of everything down to 4 ohms, assuming you use a 22R at RB14.
Thanks Tomb, I guess I got confused when i was reading last night. I do have Wima MKP10's in CA9 but used a Panasonic FM 1000uf in CA2. Maybe I will look into getting a better option for CA2 then. Looks like digikey has the Elna in stock [size=small]604-1111-ND[/size]
Now that I have it all working I'm play mode to see what changes what
