I'm not sure its as simple as that these days. It depends what price point you are looking at.
The Denon DM37DAB is a fine little unit but its compromised by a poorly designed volume control and doesn't have the resolution of decent seperates, although it is very musical. I wouldn't swap your gear for one.
The TEAC Reference 380 system I'm using is a different matter. It is proper seperates, just in a smaller size. Build quality is better than a lot of full size kit, and the amplifier is fully dual-mono in construction. Its a detailed, spacious and musically engaging listen and better than any of the other set-ups I've had here (including some pretty expensive seperates, amongst them a CD73). With good cabling and some good speakers, its very hard to beat.
If you want to go even further with the all-in-one or compact system type idea, units like the Arcam Solo Mini, Linn Classik Musik, Audio Analogue Engima and those by Primare and Myryad all give equivalently priced seperates a serious run for their money and are well worth a look.
