Glx9, very nice system. the Wilson Maxx is a great speaker and my favorite Wilson speaker. it must give you excellent dynamics and soundstageing.
i have heard great things about the Goldmund Mimesis-29 Amplifier. i would expect it to be an excellent match with the Maxx. my first high-end cables were the Transparent Ultra and they were always quite musical, never edgy or fatigueing.
i have done similar treatments in my room behind my speakers to reduce reflections. did you experiment with placement of the treatments? do you have treatments on the side walls to handle first reflections? how wide is your room?
to really take advantage of the excellent system you have, i would strongly recommend that you consider hi-rez (sacd) and analogue (vinyl). redbook cd is quite satisfying but especially analog will take things to a completely different level. if analogue is too much bother, sacd done correctly (read Meitner) will also take you to another level......and this can be done at a reasonable expense in the context of your system investment.
again, congradulations.
