I feel like I need to complete my due diligence by making that next step with the Trachorns before moving on, like Jim did with the Sonus Fabers. I would do each upgrade separately to make a fair analysis of the change.
The ALK universal crossovers kept me interested in the Khorns for the last 5 years as they made a night and day difference over the stock xovers.
PMC is still not out of the question, I need to get some input using these in a larger room (sounds like another thread in PMC).

Welcome Whatever1, thanks for the input!
