I think it is a mistake. I compared the Sony with a Levinson 37, a Meridian 508.24 and an old $300 Rotel. The Sony sounded equal to the Rotel and was not even close to the Meridian or Levinson. I think you should hold off. The prices on SACD players will be coming down shortly and other manufacturers will release their models. SACD is nice, but right now it is not worth it to sacrifice good sound on your CD collection just for a few SACD that are on the market. Also, Sony is the worst with customer service. It will not hold it's value at all.
Sony SCD-777ES as a transport
I am thinking of getting this unit to do double duty as a tranport and a stand alone super audio cd player. I would keep my current d to a and use the Sony as its tranport for normal cd's and use the Sony as a one box player for sacd's. Has anybody done this? Comments plesase.
