if you type in 'gini' you can find an interesting thread with more LS 3/5 info. what constitutes a real LS 3/5a has become a bit 'relative', so a demo (on any brand) would be a good idea. the gini with sub-unit would appear to be one heck of a buy, even if it just comes close to the older rogers/chartwell/spendor brands. good luck, and report back if you try a pair.
