When I compared the X-250 (not the .5) to the Edge NL-10 I found the Edge to be slightly faster sounding, slightly more dynamic and slightly cleaner sounding. I thought that the X-250 sounded better on a few instruments like brushes on a snare drum (more realistic). I preferred the Edge at that time, but not at $4500 more then the X-250. I could have bought a real nice preamp for that extra expense. I always found the Krell to have better bass then the Pass (slightly) but could live with the Pass. The X-250 had a slightly sweeter mid range sound then the Krell but the Krell sounded slightly more extended in the top end. Granted I heard them both with a real nice tube preamp which I preferred with the Krell and IMO the Pass works just as good with SS and tube preamps. The newest Krells 450 & 750 mono blocks are something special in the mids, they have moved away from the typical Krell sound with these amps and I am not sure if they have made the same changes to their other amps.
It comes down to pesonal preference as each amp has its own signature sound and how an amp mates to your speakes is the key to great sound.
Happy Listening.
