There is someone offering an upgrade, it's slipped past me I'm afraid. There are no probs with the pioneer one. You can in fact get 3m, 7m, 10m and 30m optical link. So Pioneer see the 30m length as needing an upgrade, but the others not. A duff or too long digital cable intoduces an effect rather like those twinkly lights you have on your tree. My advice, if it ain't broke, don't fix it.
