johny747, you have one of the best known audiophile speakers by Jamo which are not in the mega $ range.
I have heard an modified version of the Concert many years ago..was impressive
these are not easy speakers to drive, but when they are driven can give you very good sound...with Punch and more.
I do not know enough about the amp you are using...numbers like 80W are deceptive as this does not give the drivability of the amp across the frequency range. Lack of punch usually means that around the 80Hz and below is not getting the required SPL which could either be due to the room sucking this out or due to the amp not being able to drive it.
