The burning smell with a new emitter is normal but also make sure the emitter isn't touching the wires of the cage.
The sound can happen sometimes with the rheostat fixtures. If they didn't make the sound with the bulbs Puff and Chloe had, I'd switch back. Sometimes it's the bulb that causes it to make the noise, sometimes it's the fixture, and sometimes it's just where you have the switch set.
I've used one that made the noise. It wasn't loud and could only be heard when right beside the fixture.
