I have the analysis plus silver and copper. It depends upon the tone you want. The copper makes it a little warmer. Give it a try, I think you will be impressed with the dynamic improvements!
Mcintosh ma6900
I have owned my Mcintosh ma6900 integrated amplifier since 2002; it recently came to my attention that I could replace the jumpers for the amp/preamp sections with a quality interconnect. The sound quality improvement of this was startling! Anyone else done this?
