Jafant, as for recommendations, well it's just so personal. I've given you considerations from Thiel 2.4's perspective. Your room and the desired volume potential, as well as what you might have proceeding the amplification should be considered. I'm not sure if your dead set on an integrated or if not, have specific preamp considerations in mind such as ss, tubes, balanced single ended, impedance, sensitivity, etc. The recommendations I try to provide should help one avoid technical pitfalls, and narrow down the selection list to a manageable size. After that it still comes down to personal preference. If your more specific I can offer you gear I'd consider based on those parameters and if you like; stuff I like within those parameters.
