Philip,
I prefer the DOZ of course. But, I absolutely do not recommend it to anybody. I say, build it if you are curious, listen your favorite music through it and then keep it if you liked the output or discard it if it's not upto your expectations. What "I" like or hate is totally a personal preference and I think you should not take my likings into your consideration for a possible candidate for your own amplifiers, whatever music you like to hear. I like all kind of music, from Indian classical to dubstep. And I love listening them through DOZ, more than any other amps I built. I don't have those expensive systems like Marantz etc., but have listened to many of the expensive instruments at many places, mostly at my friends' and relatives' homes and recording studios; they sound very appealing. I wanted to build something which could give me the same pleasure. I built that something, love its sound. But you may well hate it. I may well run into making remarks like how "warm" "sweet" "firm" or "fat" the DOZ may sound but if I do so then this thread has gone down the drain.
I simply can not/should not convince you about the sound of DOZ. But Rod Eliott can teach you what you need to know before starting to evaluate the sound of a particular amplifier. Read through his site and you will have 50% clear idea of that "Class-A" sound, the rest you will underestand when you build your own class-A. I, however can tell you these, SE class-a sounds different from PP class-a, pure SE sounds different from phase-splitting SE(like DOZ), symmetrical class-a sounds different from assymetrical class-a, VFB class-a sounds different from CFB class-A.
DOZ's high amount of low order distortion makes its sound pleasureable to my ears, so I listen to it.
