Totally recommend the PROAC'S!!! The Mani 2's are not known to be one of there better speakers. Totem makes a few models that I would consider buying but the Mani is not one of them. Go with the Pro's I think you would be getting a more tonally neutral and dynamic speaker. IMO. Both these speakers require power to open up! I'm not thinking 40 tube watts will be the proper amplification, a great sounding SS integrated as you suggest is the ticket!
