About Musical Fidelity X-A50

Hi guys. am looking to buy a complete amplification system for my Jamo classic 10 floor speakers.. I have found Musical Fidelity X-A50 pair on sale for 450euro(i live in Europe).. and am wondering if its worth the buy.. and which pre-amp do you suggest to pair it with? My budget is around 1000e.. My other choice is a full integrated amp: Naim NAIT 5i..
Which do you think is my best bet for a hi-fi audio system?
Which other systems do you suggest me?
THanks.
