You’re right, it is all relative and, as some of us have found, there’s enormous untapped potential in a 552/500 system that is liberated with Music.
As far as the M6 is concerned though, I wouldn’t want anyone to think that a Music mains lead is obligatory. I was delighted with mine when I heard it initially with an Epic cable but found it simply got better and better as the mains lead improved (and Music was admittedly a bit of a “wow” moment).
After three weeks listening,my Chord music into M6 block is really a magic…all my disappointment and weakness I had before vanished,best upgrade I ever had
Now that you have decided that you really like what a Music mains cable adds to your system adding another then another etc will improve the sound even more.
@Meni , sell your car and buy a bike. Then buy 2 Chord Music for each of your 555 dr, and one for the 500 ps, and finally 552. And don’t forget the chord music lan cable.
The Chord Music is near 2 months salary for me. Fortunately I can access easily to bank credits, at low pourcentage. I see an N555/555 dr and Chord M6 in my crystal. Very probably final step for me.
