Legacy Audio Focus SE to XD upgrade


Are there any Legacy Audio Focus SE owners who have upgraded to the Focus XD model?  What are your impressions after upgrading your SE toXD model.  My SE's are sounding incredibly good now, and I'm a little hesitant to change anything.  
I am really looking to hear from those SE owners who have done the XD upgrade.
in advance, thanks!

Talk to Bill Dudleston of Legacy. He can give you a definitive answer. That is what I did when I bought Legacy and upgraded.
Thanks mr_m.  I've spoiled already spoke with Bill, and he was very helpful.  However, I'd like to hear from someone who has actually made the upgrade to get their thoughts.
I totally understand. I haven't owned either speaker, so I can't speak from experience, but I believe the XD has a powered subwoofer section. That said, you can expect an increase in midrange and high frequency resolution as your main amp doesn't have to work so hard to power the entire speaker. This isn't just a modest increase. It is quite noticeable and worth the extra cost. I did this with my system adding a powered subwoofer with the same dramatic results. Just my opinion though. Others may contest the increase.
Cheers
