Sonic differences between SF GP Home & SF GP Domus

Hi,

I have auditioned SF Grand Piano Domus and liked it immensely. At the same time I am seeing some very good deals on SF GP Home whch is supposed to be the older version. Can anyone please helo me by describing the sonic differences between these two speakers ? Can I assume that they sound very similar and go with SF GP Home ? I like lush mid-range with sweet sounding vocals, instruments and Jazz.

Thanks
