So I received my new Sony 555es SACD player a few days ago and have had a few hours on it. I've lived with and loved my Adcom player for about 7-8 years now. Figured it was time I delved into SACD. I used several redbook CDs initialy, ones that I'm very familiar with - Peter Gabriel, Santana, Police, Janet Jackson. All four are recorded very well and represent the pinnacle of my collection. Both players are connected via analog L/R. 555es - Did I have my sub on? That sure is a lot of bass. Checked and double checked and nope - no sub. The sony really did have more bass than the adcom. Vocals and upper-end were smoother, less digital/edgy. But at what expense? Lost was the air and transparency from the adcom. I even heard this from SACD, a loss of air. Tonally SACDs sound fantastic (thriller, boston, journey, deep forest). I really feel like I'm liking the tape with SACD, it is THAT accurate. Pros - smooth midrange, vocals very natural, bass pretty strong so much so that I may need to re-adjust my speaker position. Cons - collapsed soundstage, loss of depth So I do like my new 555es, but I may have some reservations about it. We'll see as I listen more. OH - one more thing. As strictly a transport (both players connected via coax digital) the 555es left my adcom sitting in the dirt. adcom was thin and compressed, sony even made my lowly 3802 dacs sound decent. Thanks for listening - for the price the 555es is a nice player. I've got more listening to do as to which CDP I prefer.
