Hi,
Did you notice that C112 is already at the junction of the R10 and R12 to ground?
My take is different - that C112's 100 uF is much too high a value of capacitance for this use-point. It will sound stodgy and slow. I would like to try just the minimal capacitance to do the job.
I'd like to see, at the very MOST, a 20 uF value film at that point, not 100 uF, In fact, I would start with only a 4 uF film cap there first, bypassed with another .01 uF film cap, Dynami Caps in both cases. I am listening to that exact value / type combination, as I type this post, and it sounds quite good to me. :-)
