I have only read the reviews of the DeVore Orangutan’s. I would love to listen to a set but living in Dayton, Ohio I am not sure if there are any dealers nearby me.
But I just wanted to comment that I thought I read that the DeVore speakers are high efficiency, therefore easy to drive with a variety of different amplifiers. The thing is, I believe that you do have to find a speaker/amp compatibility that is complementary and to your taste. You say you heard them with Macintosh separates but didn’t specify model numbers or if they are newer, older, tube or solid state, etc...
When I purchased my Thiel CS 3.6 speakers (a lower efficiency design that requires lots of solid state power to open up) they had them set up with a Macintosh integrated amp. The demo was just "so so". I ended up purchasing the speakers and took them home and reignited the audiophile hobby, chapter 2 or 3 for me. Sort of a mid-life plunge into the audiophile hobby if you will. I first hooked the Thiels up to my big NAD 2200 power amp and Sony CD player. I was quickly being reminded of the concepts of harshness, compression and fatiguing. I ended up purchasing Bryston components. A 4B2 power amp driving the full range Thiels. These speakers reward the listener with a type of transparency that allows you to "voice" different parts of your system to your liking.
I’m not advocating that you try Thiels. I just put it out there based on my experience and awareness of the synergy between amps and speakers. The speaker wires and the room setup and also speaker stands selected can all make a huge contribution.
