I own a CDS3. I have not had the opportunity to do any direct comparisons with other top CDPs or DAC/transport combinations, but I've heard many others in systems that I am familiar with. The CDS3 is a very capable player. It has very realistic dynamics and the kind of projection that makes it sound like the musicians are present in the room. There are other machines that give one a better sense of fine detail and delicate "air" on top, but they tend to be less "substantial" (sort of spectral and less solid in imaging terms). The CDS3 is an engaging player that makes you sit up and listen, but it is not harsh and fatiguing. It is not as dynamic sounding as some other Naim players, like the CDX2, but that player sounds mechanical and artificial by comparison.
I also like Audionote DACs (particularly DAC 5 signature) with virtually any good transport. This is quite a different presentation than the CDS3, but very appealing. The sound is more liquid and relaxed, but it is not dull or sluggish sounding either. It may not be as exciting sounding as the CDS3, but it is a beautiful, coherent and luscious sound.
