What are the sonic DISADVANTAGES of the 840c?

The differences between the better "mega-buck" players and the Cambridge 840C are really quite small in most respects. Some may be preferred for a particular characteristic or handle SACD or DVD-A, but the Cambridge presentation is simply detailed and neutral with CD. The recording sets the quality level, just as it should be. Tizz, boom, "velvety" midrange and the like are departures from accuracy and always wear thin over time. If looking for coloration, search elsewhere.

I have owned the Rega Saturn, and have had the Esoteric DV-50, and the Marantz SA11S1 in my home at the same time as the Cambridge 840c.
Compared to the Rega Saturn, Esoteric DV-50, and Marantz SA11S1, I would say that the Cambridge is very slightly lacking in the 3 following areas:
1. Blackness between notes and a completely black background.
2.Imaging sometimes slightly vague, or images not as precise around the edges as the above mentioned players.
3. Very slight lift in the upper mids/lower treble.

Break-in was not an issue. My 840c has atleast 400 hours on it.
These differences were very small, but were audible to my ears. The 840c is still VERY competitive with any of them, especially at its price.

and above all - the cambridge is very musical - that's the bottom line
