I had the Arcam A19 for a little while, and I thought it was a very nice piece for its price range. Smooth, open sound stage. I think it would be a nice pairing with the revealing Focal tweeters. Another integrated in that price range that you might consider is the Creek 50A. I've always found Creek to be a refined, slightly relaxed sound, and I think it would pair well with your Focals.
