Best speakers to partner Marantz cd63 mkii ki sig and musical fidelity x-a1

Hi all,

My first post!

I have the above mentioned cd player and amp and I'm looking to replace my old Kef C75 speakers. Unfortunately one of the tweeters is past it's best and I suspect the crossover may also be on its way out and I can't find replacement parts anywhere!

 I'm after something with an exciting listen with deep punchy bass, good sound staging and not too bright. Must be able to do distorted guitar without sounding too harsh! I'm no audiophile, just love the excitement and pleasure of listening to my favourite music.

 The music I like incudes Muse, The Shins, Bombay Bicycle Club, The Prodigy, Spiritualised, Ride, XTC, Pixies, Band of Horses etc etc etc, you get the picture.

 I'm looking to buy second hand with a budget of around £250. I'll consider bookshelf or floorstanders. My listening is around 10 foot by 15 foot with thin walls so they need to perform well at lower volumes as well as the occasional power session when my neighbours are out!

 Any suggestions would be gratefully received.

 Thanks!
