Mammen, At $1500 I would strongly recommend your considering an integrated amplifier. There are several in that price range, new or used, and likely represent greater sonic value and avoid the need for an interconnect. Am not famillar with your speakers so hesitant to recommend a particular model.
Suggestions for a good stereo preamp and amp
I have a pair of b&w 704s, which I have been driving with Rotel rsx 1057 for the last 7 yrs. My receiver is not working.I need to repair it with factory later. I also have a Rel T1 sub and Oppo bdp93. The speakers are 150w in 8 ohms. The rotel only had 75 watts/Ch, and I always thought I never did justice to the speakers. I still want to stay with 2.1 system,but need to move to separates.I do not have a very large budget, but may be able to spend up to 1500 dollars. I heard about Emotiva, but not totally sold on it.If some of my good friends who own a pair off b&w speakers can offer suggestions, that will be wonderful. This system is in the family room, not enclosed.
