I haven't heard the Silverline's but the Harbeth C7 is a true classic and one of the finest speakers ever made. It took me 2 years to find something that retained the beautiful midrange, coherence and musicality of the Harbeth but with more and better bass. You simply cannot go wrong with this speaker. Drive it with anything, place it anywhere and you will still get beautiful music. Unless you listen exclusively to hard rock, metal or dance music I'd say go for it.
