I have decide to go back to using my Leak stereo 20 and rid myself of a pair of Kwef Duettes as they are not a good match. Ok with the HK Ive been using but just too bright for the Leak. I guess them being 4 ohm speakers may have something to do with it They are also far too big for my room so I'm going small and maybe using a BK sub which I have to enhance bass. I guess a minimum of 90 db would be nice preferably 91 or 92 db. Any suggestions please?My budget stands at a max of £500 so I may to look second hand . Snell type K come to mind but they like gold dust. Also they musnt be room fussy ie back wall and corners. this is duie to the smallness of the room 12ft x 10ft .Would the small Kef Q speakers work with a valve amp?
