I have a bit if experience with the LM 518IA, and extensive experience with the CM2. I like both amps, I do not know how much improvement I would get with a LM 501 IA.
I'll give you a comment about Line Magnetic though it is based upon the 518IA set integrated, replacing the non-power tubes with NOS tubes takes the sound of the amp to a whole different level
