I was under the impression the 1bit machine were older and not as good as the newer models.....can you say a bit more about the 1bit machines and sound quality you prefer in your case as compared to later 18 times oversampling for example?? Your insight would be appreciated....
I'm not sure I can help you with that because I really don't know anything about the technology, but I know the machine is not the newest or the latest technology. I'm really not sure if the 1Bit technology is what makes it sound better, but it is the only 1Bit machine I own, with all the others being various flavors of oversampling and filtering. It is also the only Kenwood I own. The only thing I can say for certain is that my Kenwood is the best sounding of all the CD players I own and I've got a bunch.
As I mentioned in another thread, I have directly compared it to a Sony CDP-101 (1st generation machine), Magnavox CDB650, Denon DCM-520 and a Denon DCD-1100 for extended periods of time and it always comes out on top. The first three of these players I bought new, at one time or another, and the Denon DCD-1100 I was given by a friend. The Kenwood I bought for $10 at a thrift store.
What it does better is hard to explain, but it really seems to be truer to the music. The music signal from low to high volume seems to be much better scaled with smaller changes in signal intensity, but still with full dynamic range. This seems to result in more definition and better internal detail in complex pieces, with a fuller and richer presentation overall. It also seems to image slightly better than the others as well. But IMHO the differences in sound quality between CD players is subtle at best, so these differences are not really quantium leaps in quality. I listen to a wide variety of music too; from classical, to blues, to folk, etc.
I am pretty sure that the Kenwood is probably the newest and latest technology of the machines I own, so there could definitely be better ones now on the market. But, it is the best I've got. I have also been told by friends and read in various places that the CD playback quality from some good quality DVD players will embarrass some pretty high-end CD-only players, but I don't have any personal experience with this.
Hope this helps to answer your questions!
*EDIT: I should also add that I am very much an analog guy and do a majority of my listening with LPs. So it could be that the Kenwood is the most analog-like of the CD players I own.*
