As you noted the EP175 is rated at 36Hz so the extension is limited. The EP175 would work well for most music but for any demanding material such as pipe organ and pretty much every single reference quality Blu-ray movie out there the EP175 would struggle. The EP350 would be a great choice.

My choice would be option 4 .
