My "somewhat close" experience was with a well-maintained Mc2100 (2105 minus the meters) and Altec Voice of the Theaters (with large unforgiving horns, IMO). I enjoyed that setup for about ten/fifteen years, with TTs and later with CDs.
As I branched out, starting in about 1990, I found that many amplifiers -- including Mc SS and certainly the Mc60 and Mc225 amps that I still own today -- sounded smoother. I attribute the harsh sound to the 2100, and I'm sure the PA horns of the Altecs emphasized the harshness I heard. I don't know, but I would expect the Klipsch voice will be slightly or significantly more forgiving.
Of course, depending on room characteristics, equipment arrangement, music source, and music mix, your setup will be different.
Let us know how it goes.
