I owned a pair of SHL5 (non-plus version) and found them to be as you described the "plus" version. I've since gone back to Harbeth 40.1's as they are full bodied and far superior to the SHL5 in my experience. If you are patient and ok with buying used, you can find a pair of 40.1's for around $7K. Another speaker to consider that I've heard at a friends house on several occasions is the Verity Parsifal Encore, which is superior to SHL5's, is full range and can be found for around $6-$7K used.
