Don't know what it would cost you to go Krell, but my guess it would be a decent outlay for marginal, at best, improvement. Particularly in that your focus is HT.
I went Krell because my focus is music! Why go Meridian if you simply want to watch movies - surely Sony will suffice for that.

I figure that my system gets used 80% for music and 20% for movies.
And your comment about marginal improvment, while certainly true, is central to the debate over spending $$$ on hi-end audio (or hi-end anything for that matter). Why spend for 861 when it is only marginally better than G68; why buy $20,000 speakers when they are only marginally better than $5,000 speakers?
The answer is a personal one - is all about value for money and what makes personal choices unique to each of us. For me spending more for a Krell over say, an adcom (excellent amps in ther own right), is worth the marginal improvment; where it may not for you.
Plus the KAV 3250 amps look really cool
