@ Bill - I agree with you on this line - "With cocobolo, you're getting a darker, more impactful, bass but that does effect the tonal balance." I feel the highs on the 325s are tamed down to just-right levels by the cocobolo, which is probably why the darker nature of cocobolos and the brighter 325 drivers go hand-in-hand. And pads, yes, that is another thing. Somehow for the life of me, I just can't get jumbos to work for me since the cocobolos got fitted and I don't know why. Personally, I feel the sound becomes less engaging / intimate. This is where the bowls gets it right and has one-up over jumbos with cocobolos. Although I am hoping to be able to go back to jumbos someday since they are more comfy to my ears than the bowls are.
@ Lawrywild - nice to see the alumod reached you. Have fun with it and I look forward to a good review or two :)
