Does anyone have any experience with current or recent Onkyo receivers? I'm noodling a new receiver and like Onkyo. The new models, 607 and 707, seem a great value for my needs. But I've read reports that they run hot, which I'd somewhat ignored. However, a visit to BestBuy left me surprised at the very hot -- painfully hot -- Onkyo receivers in semi-closed shelving. And my media cabinet is closed, with the receiver under a TivoHD. So I'm looking for some insights to either assuage my concerns about a hot-running receiver, or in confidence in rejecting a hot receiver as a bad design for closed cabinet. I appreciate any experience or insights on the matter, especially on current Onkyo receivers.
