SC-V's were a popular mastering monitor. You might want to check out this review

To summarize, the review says ATC 300's have an advantage in dynamics and SPL levels; rockers liked ATC's more. The review gave DAL SC-V the edge with classical engineers/listeners. Both are highly regarded for studio monitoring.
This is only a suggestion, but a smaller ATC, such as the tower version of the 50's, might fit your new room much better and still keep up with what you are used to from DAL SC-V's (accuracy, dynamics and volume levels) although you may lose some of the ultra LF. It might be worth a listening session to compare.
Another possibility might be PMC's. I think you will get more bass extension from the TL design than ATC's. You might find this to be closer to DAL SC-V's in the ultra LF bass...then again you may like the tighter less bass heavy ATC's...all a matter of taste.
