Distortion on audio recording related question!

Hi everyone! I am not sure if this is the right place to post a question about a problem that I have concerning audio recording but I will just try. I am having some trouble lately while recording with my condenser mic in my home studio, the vocals have a kind of hiss sound and therefore sound a little bit distorted as if it often gets close to clipping. Already while I am recording the vocals I can hear the distortion.

Some details about my setup, I use: Neumann TLM102 Condenser mic, Apogee Duet2 A/D converter, Mac mini and Logic9 as DAW. I have used the same equipment for years and never had any problems. Nothing has changed in the settings, of my A/D converter for example, or software and I am recording my music the same way as I have been doing the last few years. The input level on my apogee is not too high and I know what level normally suits my voice and music style but even when lowering the input level the problem remains. The recording is not clipping but it still sounds like it. On my DUET I also use the 'Soft limit' setting which is an extra tool to prevent clipping. I tried with another (dynamic) mic but the problem remained. So maybe the problem doesn't lie in the condenser mic. I recently moved into a new apartment and, unless it's a coincidence, the problem seem to have started from there. Could it have anything to do with an issue concerning the room or general power supply (since the light in the ceiling make some kind of buzzing sound)? When I record I turn off the lights though, and I guess it's not because of interference because the noise is not continuous, it seems like a gain related thing but I don't see how? It is definitely not an ideal recording room but could reflections cause anything like this to happen? (I use a pop filter and isolation screen for the mic and phantom power 48v, I don't have any latency issues...)

I have tried to be as detailed as possible in my description. I will be thankful for any answer or suggestions. Jordi
 
The first place I'd look is the Apogee Duet. Digital interfaces CAN go wrong and it seems to be the common link in the chain.

FMI, does Apogee provide specialist drivers for use with Mac or do you just use the built in Mac sound card? I ask because a few years back I had a similar sounding problem and a driver re-install (I'm on Windows) sorted it.
 
Hi Bobbsy,
Thanks for your help I will look into this, starting with my apogee. Maybe it could be solved with drivers too, although I guess that is maybe not the most likely option, the computer I am using as well as my A/D converter and DAW it all belongs to Apple that's why I doubt it's a driver related thing. As I said I have always had the same setup and worked just fine till now, nothing has changed but the location so I am starting to think it could be a power problem, that could maybe be solved with a solid power conditioner? Thanks again.
