OVer many years, I've never heard a home audio Bose setup that sounded even marginally good to me.
Maybe some tube or very good other modern amplification would help? Possible.
One thing I'll say about the 901s, having not heard a pair outside of commercial setups in quite a while, is that their price point relative to the high end is probably more attractive than ever. They used to be one of the more expensive speakers out there for enthusiasts to covet. Now they pale in comparison probably in most ways to the current "high end".
They seem to garner a lot of positive ratings on various sites that measure these things though, no denying that. So someone out there is dropping decent money on them and liking it.
