At the risk of sounding like a broken record, my go to mic for a lot of vocal recording is the sE2200A (I now have 3 of them). It has a nice smooth response and just enough warmth to my ear but with lots of mid and upper mid detail. There are now two versions--a multipattern switchable and a fixed cardioid. For vocals only, the cardioid is likely the best value. If this is more expensive than you like, the sE2000 and sE X1 both have most of the good points for lower prices.
Yeah, I know, I know. I'm an sE fan--it stems from living about 5 minutes drive from their original UK headquarters before I moved to Aus--I got to know the guys and try out most of their mics! (I have a few mixes on file done with nothing but borrowed mics--wish I could still do that!)
Outside the sE range, I'm also a fan of the Rode NTK which is also worth a listen.
As for the room effect, unless I have a properly acoustically treated studio, I'm a big fan of close miking and simply dropping the room out of the equation as much as possible. I agree that the quilts etc. may be attenuating the HF--but this only matters if you mic is far enough from the source that the room is a factor. Get up close and personal via a pop screen and the room matters a lot less.
