I use Virtual Dynamics Master LE 2.0 power cord with my MC501 and got incredible result. It is better than an amplifier upgrade and has all the characters you described, music sound more organic overall. I have tried different brands of power cords including different lines of power cord from Virtual Dynamics, so far the Master LE is the best that I've heard by a huge margin. Now I have stopped looking and just enjoying my music.
Best power cord for McIntosh MC 501 monoblocks
I'm looking for suggestions/opinions on what power cord to use with the McIntosh MC-501 monoblocks that will bring out detail and transparency without boom or being overbloated. I presently use a pair of Acoustic Zen Gargantua II, very nice, however I'm seeking something with the characteristics described. Thanks
