Listen to these clips, Do I need room treatment?

After upgrading preamp from DMP3 to Great River ME-1NV and still could not hear any improvement in the vocal, I began to question the acoustics of my untreated room.

Some said that a good vocal recording can be obtained in an untreated room if the singer stands fairly close to the mic and keep the gain at a low level. I did just that (no computer noise or clock-ticking noise ever got into my recording, not even sounds of the dog barking in the yard or of occasional cars running by).

Maybe I just can't hear the difference due to my untrained ears or low-end monitors. However, I can clearly hear the high quality of the vocal in the professional sample. Please have a listen (these samples are in Vietnamese):

2. (Wet vocal with backing track) http://www.lightningmp3.com/live/file.php?fid=5466
3. (Professional Sample) http://www.lightningmp3.com/live/file.php?fid=5467

Question: Should I get either blankets or 703 panels to absorb the reflections during vocal recording? What else can I do to imitate that professional vocal sound?

Is this maybe a mic issue-- were the mics used the same? Did they also us a GR for the "pro" sample? Are there eq differences between the two samples as well? The pro sample seems to have more higher frequency stuff going on.
If this is a room issue, maybe some baffles would help. You can get the Auralex Aural Xpanders for like $35-45 on the bay, sE makes that crazy Reflexion filter thing for like $300, and I've been thinking of picking up a "modtrap" from here: www.modtrap.com
The modtraps are apparently made by a couple of TapeOp Diy's and are brackted, mountable 703 panels that mount on mic stands.

samples 1 and 2 used same mic.

No, I don't know what mic or preamp the pro used.

I just wonder if making a portable vocal "booth" with 703 panels (similar shape to the Reflexion Filter) will help improve the vocal or not. Or do you think it's good enough already?

It definitely sounds like the room is having a negative impact on the first dry sample. But primarily, I think it sounds like a drastically different mic with a different frequency respose.
