I would like to switch HDMI components, provide for storage of I-Pod and MP3 format music (with on-screen menu please). Wanted, but not necessarily needed (depending upon performance and the Group's recomendations) would be the ability to change and shape crossover points.
There are lots of good choices from the top tier manufacturers. They differ slightly in terms of features offered at a given price point but all are remarkably similar, except for possibly ease of use and design of the menus and control functions.
- re: switching HDMI: I would not buy a receiver that is HDMI 'pass-thru' only as they cannot process the audio which kind of defeats the purpose of HDMI switching. You want HDMI repeating (often labeled 'switching', which is incredibly confusing because the pass-thru receivers can also switch). The entry point is usually around $500 (new - retail).
- re: iPod and MP3 storage: The best solution is separate from the receiver; in other words, just another source device to the receiver as opposed to a receiver with built-in ethernet streaming capability (very limited and always bug laden). If you want on screen display, you'd look for iPod docks from the same manufacturer as the receiver. With a dock, you can use the receiver remote to control the iPod and get on screen display. You don't
need a dock because you can connect the iPod to any analog audio input.
- re: xover points: Nearly all brands now offer independent xover selection per channel. I don't think that is a big deal unless your speakes are kinda mismatched where the mains may go down to 40 Hz, but the center and surrounds can only go down to 100 Hz.
The ability to grow the system over time would be a plus.
With enough inputs, HDMI switching, and support for the latest digital audio formats you can expand simply by purchasing new source devices and will be reasonably future proof for awhile.
Most of the time when people are trying to think of future expansion they tend to mean the ability to add an external amp later. That requires a receiver with pre-outs for all channels and that issue will make my point that all the brands differ only slightly at a given price point; eg. at the $500 price point some Yamaha models offer pre-outs but not HDMI repeating; at the same price point Onkyo offers HDMI repeating but not pre-outs.
