I have been gradually improving this system to provide wonderful relaxed sound in a medium sized basement room. This is it for me. Ever improving has reached the end of the line. Time to relax and enjoy the music.
What are you changing your speaker wire to?? I notice you have Sablon single wire! I have heard the Sablon biwire with ground yields a huge improvement over the single wire! You may be able to get a large gain with a small investement!?
