B&W DM7 Kenneth Grange classic

[Guitarrero]

Thinking about getting B&W DM7 speakers and wondered if any here have experiences or advice.... good or bad!
I like the B&W sound but could not afford them in the late 70s so had to settle for DM10's and later DM110's, both of which I still have.
I have heard that they like a reasonably powerful (100w plus) amp to drive them properly, although the factory advises that they are " Entirely suitable for all high quality amplifiers up to 200 watts rating" ..... not sure if my Quad 33/303 will cope?

Thanks in advance,
Steve
