You didn't mention power cables on your Triton 2+'s. I have a pair of these speakers and used Blue Jean speaker cables on them for a little while.
I upgraded both the PCs and speaker cables and noticed the biggest difference in the speaker cables, but at least a modest upgrade in power cords is worth doing.
I tried a few different speaker cables from Nordost, AQ, and DH Labs, and decided I liked the sound of the DH Labs Q-10 the best, but I have different electronics and front end. None of these were terribly expensive, but I thought the AQ (Mammoth) and Q-10 cable was a nice improvement over the BJ cables. I'm sure you could do even better with more expensive cables if you have the budget.
