Hello, my current system is a Sony DN610, Tannoy SFX5.1, 40NX713, and bdps370 I'm looking to upgrade the blu ray player as load times for films are killing me. My problem is with no real budget I've picked 3 that cover a range of prices, but don't really understand the offers ces between them. Musical capabilities will become more important so that is one factor, also I don't play DVDs so am not interested in up scaling capabilities. I don't know which have 4K up sampling but imagine that will become more important as the years go by. My choices are BDPS490 (£90), BDPS790 (£200), or the UD5007 (£350). So can you help me with this choice, I like the marantz most and the BDPS490 least, but don't know what extra you get as you move up the price scale.
