I own a Sony SACD player. After a couple of years the player started refusing to read the DSD layer of some hybrid discs. Initially it was only one or two but now with over half of my SACD's the player won't recognize the DSD layer only the redbook/CD layer. I have tried everything I can think of to no avail. Someone told me that this is the beginning signs of laser failure and that it will continue to get worse until one day my transport will fail to recognize any discs. This is supposedly a fairly common problem with Sony transports. I don't know if Krell uses Sony drives or not, but it might be worth checking out.
By the way I hear that the new Sony 5400ES is a fabulous player, but, it has no multi-channel analogue outputs, so if your pre/pro has no facility for multi-channel decoding of SACD via HDMI then it wouldn't be a very good purchase.
