I feel a separate 2ch system apart from your HT is a very good choice. While yes, the HT stuff changes like the wind, a solid 2ch setup can be enjoyed for years with very little care of up grading. This gives you the options to have a very nice musical set up that does not have to service a dual purpose. Analog is a great thing, set up in a bedroom or quite office away from your over sized theater system to be listening to in comfort and privacy.
