recommends for interconnects?

i would think between mac ss workhorse amp and levinson front end a tonally balanced, neutral cable would work well, maybe even one a little yin leaning

kimber or upper wireworld or medium grade nordost should work well, dh labs silver would be a nice pretty cost effective option

Product specs say your Mac 402 is a fully balanced amp. If your Levinson pre is also fully balanced you can use microphone cables and save a lot of $$$. I use  XLR Mogami W2549 balanced microphone cable between my pre and amp with excellent results. Any EM interference/noise, coloration, cancels out if your gear supports the balanced standard (AES 48). If your pre is not a balanced design then you are left to expensive ICs for tonal controls. Look at my system for details.
