Magnepan LRS- what amp should i consider? (sub $2,000)

I use a Crown XLS 2502 on my 1.7i and the sound is absolutely fine. I have other amps, A/B Rotel RB 1090 that works great also but get super hot if you play them long enough. Also have a Denon optical class A amp that works just wonderful with my Maggie's but despite what others say about the Crown XLS amps they work perfectly fine, I have never heard the fan run ever and quiet enough background but if you wish you can drive the hell out of your Maggie's all day and the Crown never breaks a sweat! Uncolored sound, honest sound it just amplifies what is there and sounds perfectly pleasing at a fraction of the high dollar amplifiers new or old. Just saying...the 2502 is about $649. Plenty of amp on the cheap that plays Magnepans just fine.

I just grabbed a Nad c298 power amp. It replaced an adcom gfa-545. I loved the way the 545 sounded. The older adcom power amps lack a speaker protection circuit though. I just got the klh model 5’s and didn’t want to take the chance with an older 545 even though I loved the sound. It’s rare, but they can fry speakers. The c298 is at the very top of your budget at $1999, but it uses a newer class d module that sounds amazing, very detailed and tons of power.
If you don’t care about the speaker protection circuit. The older adcom gfa-555/555II have 200 wpc, and would suit your purpose. You can find ones in great condition for sub $500 easily. I don’t know much about the newer gfa-555se, or if it has speaker protection. Love the older adcom sound.
If you’re interested in some of the newer class d amps though. I’d recommend investigating. I’m happy with my c298. You can find many that are plenty powerful for cheaper too. Look for amps that use ice power, hypeX, ncore, or purifi modules. If I hadn’t gone the separates route, I’d have probably gotten the rogue audio Sphinx, which someone already recommended. Tubes plus 100wpc of class d 👌.

I currently feed my LRS's with a Parasound Hint Integrated. As mentioned above, a sweet combo. It has plenty of current, John Curl design and is a virtual Swiss Army knife of an amp. I decided to consolidate gear awhile back using the Halo INT as the centerpiece and have't been disappointed. A solid DAC, Bass control (I run 2 Speedwoofer subs) and phono section makes this a quality one stop shop.

I also had a very good experience with a Wyred STA-500 I think it was. Class D but sounded quite good and plenty of juice...

That is a speaker that requires a amp stable to under 4 ohms 
to get proper control ,not much out there any good at $2k 
maybe parasol do, or the Anthem bipolar amp 250 wpc is solid 
safe and sound audio has these and gives good deals .
