I went to the Partsconnexion web site. Replacing the output ICs in the Benchmark may have an audible effect (though I'm not sure why, since the Benchmark measures so well, analog-wise), but they lost me on this statement:
"The caps and resistors chosen in this mod simply have better tone and ambience characteristics, as well as being higher resolving. The wire and connectors we use allow for enhanced detail and more precise imaging."
Caps, resistors, and intra-box wires don't have "tone and ambience characteristics". This smells like BS. You'd also need modded and unmodded units side-by-side to even make a cursory decision about which one sounds better.
I'm still fascinated by the consistent conclusions that the ML units are such obvious winners.
