I ended up not following my advice and put the mostly Class A CODA #16 on the LRS+. It is definitely the best the LRS+ has sounded. The LRS+ can really use the power and current. My Sanders Magtech (Magnepan + Tech) was great on the LRS+ at 500 | 900 watts @ 8 | 4 Ohm. The #16 is a bit better on the bass and a bit cleaner on top. I think the Sanders is the best Class AB amp I have owned.
I will be getting another CODA amp to replace the Sanders, which is on my other system.
Maybe a better LRS+. I am staying with the LRS+.
