I own 5As and would look at it this way; In a 3 sig / 2w system with components that one might expect, IMO inserting 5As would be something of the difference you have above with redbook CD and HT. But the "gap" would widen if one upgrades the rest of the system (likely spending a lot more)and adds a really good vinyl setup.
If one has an Ipod as the source, who knows, we may be talking about only a 95% dif.
