My experience with upgrades on Amp and speakers have been very positive , feel always was rewarded by much higher performance by several folds compared to the cost of upgrades.
I would have even asked the OP to consider slightly higher range of caps like Clarity ESA or MR instead of PX. More ever, you could have gone for upgrades on internal wiring : these things do make lot of difference.
