A slippery slope, this one........
Any time you get into a discussion with audiophiles over what method or brand is best, the landscape gets slippery, fast. Go with what your instinct tells you, the sound is really an individual choice. You have some great speakers. I don't think the mis-match is a big issue, unless all listening is concert-oriented. I have cobbled systems too, and find them very satisfactory. Add a sub if you wish. It's all about what you really want. I feel that speakers blended from different origins are ok if some thought is given to the process.
