I also had the 1C's. Even though they're not too expensive, they are very detailed and revealing. Because of that, its very important to match your components correctly. I would recommend a Creek 5350SE (Either the old or new version. It doesn't matter.
The main reason I would pick the Creek is for the pre amp section. Its passive. I feel its very hard to find a good active preamp in your price range, let alone as part of an integreated. The passive preamp will allow you to get around some of the problems you run into at your price point.
Also, the 1's are very easy to drive. You can use just about anything. The amp in the Creek is more than enough.
