I am trying to decide whether to spend an extra $300 to get a Marantz SR7300ose rather than an SR7300. Given a limited budget, is it worth spending that extra money, or would I better off putting them towards speakers, sub, etc? All things being equal, is the sound of the ose clearly superior to the base model? I'm planning on enjoying the receiver for a good long time so I'm willing to make the extra investment if it's truly worth it, but not simply so I can have gold plated inputs or "hand selected chips" , if you know what I mean. (And no, I can only consider Marantz, not other brands at this point, and the price difference is $300 for me.) FYI, I'm planning to purchase B&W 602's (or 602.5's?) and an LCR60 (or LCR600) for my fronts (using my reliable old Polk bookshelf monitors for now for rears.) Can wait to get them. Thanks for any input.
