Integrated advice for B&W 705's

What made you buy the 705s?  Did you hear them and like them at some point or was it just a blind purchase?

Thanks for your replies! 
I did get a change to demo them prior to purchase but probably not long enough and with a wide enough range of music.  There are aspects of them I really like...very clear, nice midrange and better bass then my previous setup.  Also harsh maybe isn't the best description, perhaps a little too bright sounding is more accurate? Sorry still new too the whole audiophile scene and descriptions.    

I've have looked at the Rogue products and they look like they may be a good fit with the tube pre-amp.  I've also been looking at the ARCAM SA20 and Musical Fidelity M2Si based on pricing and seems like some positive reviews online, although I'm learning that getting thing paired well is very important and don't work well in all systems.  

Many love B&W speakers. I am not familiar with the model that you have, but any B&W that I have heard always sounded too bright for my taste. I doubt that replacing your amp will change the character of that speaker!
