Reply to PMC05 Pro IV or Z2

My current setup is an SMX-201, 2x STR8-80s, A10, X1, MF3D and a bunch of vinyl to play with, too.
I'm looking to upgrade my mixer that is better suited to scratching.
I've narrowed down my Z2 and ProIV.

I don't need all the midi functions or the soundcard in the Z2, but I've read good reviews about the CF, not so much the LFs. I also don't like the lack of a send/return for when I want to go with just vinyl and my KP3 for effects.

The ProIV would be a no brainer for me if it weren't for the hum I've read about when the midi functions are used.

All I want midi wise is a few encoders and buttons for selecting tracks so I'm not playing with the X1 all the time and I can use it strictly for effects in Traktor. Also XLR outs which they both have anyway.

What I'm really looking for I guess is if anyone has used a new ProIV recently to find out if the hum is still there since I haven't found anything new about them since 2011.
