Sony XBA-2ip vs XBA-3ip, is the upgrade worth it?

[MrGuzmanWhite]

I have the XBA-2ip that I purchased 4 weeks ago, and now I have the opportunity to grab the XBA-3ip for even less cost of what I paid for the xba-2ip (I can get the xba-3ip for USD$100). I like the XBA-2ip is some sense but not in others so i wonder if you can advise me on the rationale to upgrade and get the XBA-3ip.
 
Things I like of the XBA-2ip

1. Very good clarity
2. Reasonable soundstage, and good instrument separation
3. Good mids albeit I find the voices a bit "unnatural"
4. Good highs but somethings a bit to edgy
5. Very comfortable, good fit for my ears

 
Things I would expect the XBA-3ip to improve to justify the upgrade

1. More body in the sound, the XBA-2 sounds a bit too thin, perhaps sounds a bit too bright and I would like a bit more warmth without losing clarity
2. More bass presence
3. Better defined highs, not so edgy
4. Similar comfort
5. Perhaps wider soundstage, and perhaps better intrument separation (albeit I am fine on this with the XBA-2)

 
Anyway, please let me know if the jump from the XBA-2 to the XBA-3 would improve the sounds in these areas.
 
Thanks indeed.
