The Mahis are not balanced and I have never tried to mix the two. My suspicion is that they would work fine with other balanced components.
I bought the Shindo purely on spec.
I really like the LV IBX speakers. One word I would describe them as, is "fun". They are very lively and dynamic. They have the great quality of being both detailed/revealing and very listenable. I have had some trouble placing them but I have room that is problematic. My placement is a triangle of 12' and 2' off the side and back wall.
This is a relatively new system and room and completely different than my last system which consisted of a 600 watt Mac and Eggleston speakers. I like the direction I'm going, especially, the Shindo. Depending on if I can get the LV's tweaked out exactly the way I want them, I will probably get a Shindo amp (Cortese??). I think the two brands are a good synergistic match.
If I eventually decide on a different kind of speaker which would be a better fit for my room, for ex. a non-efficient monitor, I will definitely keep the Monbrison and match with an appropriate amp/speaker combo.
