Crossover with variable slope and time delay

I have a Devialet Expert 400 running Wilson-Benesch Vectors with a distributed bass array powered by a Dayton SA1000. I am considering upgrading and was initially simply going to replace the D400 with a D440 but I do not want to rule out other components that might also fit the bill. Willing to go integrated or separate. I also need a moving coil phono input and DAC is desirable since I have limited space and wish to maintain the WAF. I think 150 watts at a minimum, recognizing that not all watts are created equal. 
I have looked at Bel Canto Black, McIntosh, Levinson, Anthem, Trinnov Amethyst, Legacy Wavelet, and others. 
I believe time correction and the ability to apply different slopes is important. Happy to be convinced otherwise because it opens up possibilities.

Thanks for asking, Erik. 

I am considering the addition of room correction as well but at this point it is of secondary import. It would be nice to have but its absence is not a deal-breaker.

Understood.  It is daunting to try to match everything by ear alone, recognizing that I have now opened up Pandora's box for those who will say you should only trust your ears.  My feeling is the ARC should get one close and then tweak by ear. I have tried the subwoofer crawl and found it did not lead to significantly different placement than my room dimensions, openings, furniture and wife had already defined. I Guess I'm either lucky or deaf.

I appreciate the option of the miniDSP and Behringer.  Makes separates or an integrated with pre-out/amp-in more attractive and greatly increases my options.
