At this setting it is a very subtle but very effective. I used to own a Porta Corda MkIII-USB and I thought the crossfeed was excellent. I can only assume that the current Meier amps use the same circuit.
I currently have a Corda Cross-1 crossfeed which I use with my main rig for comparison. The XM5 crossfeed is equally effective for me although I haven't done any critical testing between the two.
Actually I did back off the default setting a bit for the review - as default the flat part of the xfeed knob was at about 2 o'clock and now it is turned down to 12 o'clock.
Basically the XM5 Xfeed still improved the extreme L-R spread program material to reduce the "pressure" effect on the opposite ear, but the effect was a little different as I described in my review. I still cannot listen to that CD without crossfeed, but with the XM5 and 3MOVE or Micro Amp I can. The XM5 seems to bring the far left/right instruments closer to center stage, but they also feel closer to the listener to me; while the 3MOVE brings the far left/right instruments around closer to the center but not closer to the listener. This sounds just like my Headfive crossfeed as well. My Headroom Micro Amp crossfeed is closer to the Meier crossfeed but unlike the Meier which does not change the tonality or frequency response, the Headroom's sound seems to get warmer and slightly more rolled off.
I have the Corda Cross kit, but haven't sourced the parts list or case for it yet, and will need to hire someone to assemble it for me.
