very true Steve, I like sensitive speakers, may I qualify that its important not to think just cos a speaker in a shop a/b demo IS better, because it is louder side by side. This is the natural effect, the louder one(more dbs) makes quiter ones(less dbs sensitive) sound limp and lifeless.

Of course they must be heard at the same level.

At the cheap end of the scale, ie the £200 level, this phenomenon is well known, and some makers do exploit it for an A/B demo in the shop.
