I've heard the Atoll IN200 as well as a combo of one of their seperate preamps and amps, and they both sounded amazing, and completely caught me off guard. I was really surprised because I prefer tube gear, I personally have Audio Valve Baby Baldur monoblocks with their Eclipse preamps, and while the Atoll didn't measure up to these, it was still enjoyable to listen to and very musical while costing a fraction of the price. So for the price I would highly recommend it. Actually as I'm starting to get into analog more I'm considering Atoll's p200 phono preamp to start off with. I'd demo thier integrated amp first if you can you you can make sure it has good synergy with your system (last time I upgraded my speakers I made the mistake of not listening to them in my system and then spent more than twice as much upgrading my preamp and amps to the Audio Valve ones I have not to get the speakers to where I wanted, and actually significantly better than they sounded at the dealers house).
Anyway out of the other recommendations that have been made while I didn't prefer the Audio Research VSi60 in my rig, I know a lot of people who do like it a lot so if you can afford the extra you should consider it. The other integrated amp besides the Atoll that I would recommend is the Cary Audio SLI-80. Like the Audio Research VSi60 the Cary Audio SLI-80 has also received great reviews, it has a bit more power and also retails at a two thirds of the price of the VSi60, so it is much closer to your original budget. I've listened to both of them and definitely prefer the Cary over the Audio Research. I also prefer the Cary over the Atoll.
If you do end up with the Atoll, make sure to invest in a good power cord for it because Atoll responds really well to good power cords. Hope this helped and good luck.
