how's your room acoustic conditions?
KEF Q300 should be better in term of phase by their speaker design
Elac Debut B6 uses fabric tweeter that might appears as softer highs.
both of them needs amplifier since they're passive
I have no idea about those active monitors as I havent heard them in person
but, monoprice 8 should have a better low-end energy since the cone area is bigger than the rest
how the sound stage, depth, and separation is depends on your acoustics. they're well known products. the most importance is, which speakers that fits to your sound signature? have you try them in person?
