I've listened to a P25 and a P5 on the same system: ProAc D25s, with Ayre V-5 amp and K-5 pre-amp. The main difference to me was the P5 had more weight in the bass. The P5 was a little more rhythmic, marginally more extended treble. Both models are extremely reliable and easy to use. I bought the P25 as a demo, and with the savings haven't thought twice about it.
