I wouldn't rule out Kharma loudspeakers.There are usually many at all ( used )prices and the Kharmas ( all of them ) do the dissapearing act very very well.I have heard both MBL and Kharma ( not at the same time )and they both are incredible speakers....I purchased the Kharma 1.0 used a few years ago and I will be honest I would be hard pressed to find a more enjoyable speakers. I think the big thing is to find the right size MBL or Kharma to fit your application.That is the real test for you....Good Luck
