I’ve swapped the positions of my CD5XS and NAC152XS on my single stack of Isoblue. My NAC is now on the top, the CD player on the next shelf down.
This is preferable it but find it hard to put into words why. Something about the way the music flows?
I know this sort of topic is old news for many but I pass on the info just in case it’s useful.
Best to All, C.
