Seems that the lamm will be more laid back and "slower" in comparison to the solid state parasound. Just depends what kind of sound your are looking for and the synergy with your amp. Parasound will be
more punchy and dynamic, so the more expansive lamm may not be an upgrade if the type of sound you are looking for fits more with the parasound.
