Thank you to those members who have responded. Looks like I am back to square one again. Nevertheless, I may just go with the Cambridge Audio 840C. I say "may" because I always thought of Cambridge Audio as glorified mid-fi.
To Jafant, I was not particularly interested in getting into SACD. As I indicated I have read several times on this site that SACD can/could enhance the sound of redbook CDs, but ZD542 claims otherwise.
Yes, the Saturn would be a wise choice( especially if it is a major upgrade from the Apollo). There has been a dry spell for used Saturns on AG; and, unfortunately the two which recently surfaced for sale on AG, had their transports replaced by Rega.....Not exactly a vote of confidence for that model.
I have found from experience that Rega products are very reliable. However, I don't want to spend $1100 for a used Rega Saturn that may have the same problem again, or laser problems. I will not spend half Saturn's original retail for a new one. The player's design is at least 7 years old, and the player was grossly overpriced when it was came on the market in 2006.....I appreciate your comments.
