Warmer class D amps for magnepan?

I am planning on buying a pair of lrs+, and i need a poweramp. I am well aware that class D is despised in the magnepan community, but its unwarranted. Nuforce and the new purifi amps are designed to handle 2 ohm loads, and have been used to power Maggies without falt. My only concern is they will kinda rip my head off if i play any less than perfect recording on them. I’m aware that all modern magnepans are unforgiving, but can be tamed with a smoother amplifier. So why not class A or AB? Unfortunately, i simply dont have the space for the ones that are actually rated at 2 ohms (the lrs is around 3.5ohm, but dips to 2.8, it MUST be able designed to handle a 2 ohm load). Also, any one of them that does go up on sale, the owners almost always refuse to ship them, and want you to pick it up in person (for which i dont have the resources to do so). So I ask if there are any smoother, more forgiving class D poweramps (not intergrated models) that you are sure will power magnepans correctly. They can be discontinued, as i will be buying it used regardless, so anything from 2008 to 2018 would be preferable and my budget is around €2000, so say $2500. Thank you.

The CIA amps also look like a very good option, and are in budget. I would love to try the D sonic amps as they seem to be rated very highly with Maggies, but again, simply not available in Europe even on the used market (also, i apologise that someone already mentioned the AR amplifiers).

I've used several amps on my Magnepan 1.7i's. I had the Bryston 4BST in stereo putting out 500 watts into 4 ohms on them and it wasn't enough power. I bought the Legacy Audio i-V2 Class D 1000 watt stereo amp and it's much better, more detailed, more bass. I'd highly recommend the Legacy Audio i-V2 for your class d needs. I'd also like to try dual 4B's in bridge putting out 1600 watts in 4 ohms, I really think that 1600 watt range is what you need to get the ultimate sound out of Magnepan's.

I’m using a Wyred4Sound STI-500 integrated amp to drive my Magnepan LRS speakers, and they sound awesome! I used to have a pair of Martin-Logan Requests driven by a Krell FPB 200 and a Pass Aleph P preamp which were both Stereophile Class A grade pieces, and were awesome, and I was recommended to try a Peachtree NOVA 200, which is a Class D integrated amp. 
I tried it and it sounded awesome……I learned that it all depends on the design of the electronics more than anything else.

D is for subs and people who don’t know better, and think they are amazing,….nope,..you may think it sounds great, compare with A or AB, HUGE DIFFERENCE

I've heard a number of class D amps that sound better than A and AB amps.

in your price range, you’re not going to get proprietary parts are going to get junk buffers, industrial grade cheap caps and just off the shelf class D modules with inexpensive wiring.

This statement is false. Cost has nothing to do with getting the input buffer to perform (and sound) really good. You certainly want industrial grade capacitors- that way they hold up. Nor would you be limited to off the shelf modules...
