I asked in an earlier thread whether anyone has used the new Yam S550. Having received no replies, I am now asking if anyone has experienced the older S540? I know there are a few good reviews on the machine, but I would like to hear from a long term user whether they are good solid realiable machines, and how they perform visually and sonically. I have tried numerous DVD players now, and I am fed up of taking them back for various faults, bad quality etc.. I have a AX640SE which I am very happy with, so I think it may be a good idea to go for the new S550. The customer suport is also very good at Yamaha, which is a big factor in my opinion, unlike Pioneer and Cambridge Audio! Any help appreciated.
