I recently bought Boston Acoustics CR65 (8 0hm) bookshelf speakers. I want to use them with my laptop or Kindle Fire or Flatscreen and looking for quality sound. Right now, without an amp I get very little sound with volume maxed . I have tried them with garage receiver so I know they are great sounding!!! Could you suggest a small amp or whatever you think is best. I only want to spend about $150 at most. Thanks!
