@stephendunn since you mentioned the Enleum, I just looked back the posts and realized that I have never posted about it. Recently I snagged one from a local audiophile buddy who was using it as a headphone amp. He has never hooked it up the speakers. I was not very confident that this tiny little amp can do any wonders compared to my modded LM SET. Well, never in the past I have been so wrong about audio the first time I have hooked up my system to the 23R. Just before I snagged the Enleum, I bought a new pair of Psvane ACME 805 for the LM and I had only played about 10hrs before the 23R took its amplification duty. So far, I have not turned the LM, neither I have the urge to do it. I will probably compare at some point but I can say that the sound from the Enleum is very satisfying.
I had a SR orange fuse laying around and it took the Enleum a notch or two up. Now a SR purple is on the way.....man, this hobby is just nuts :-)
I will update on what I find out on the CTD...
