Well, of course I could not wait for the Amperexs to arrive. The Dodd is really wonderful. It seems to have the dynamics of the CAT SL1 which was the best I've had in terms of dynamic contrast. It seems to have the quietness of a passive, which may account for the great dynamic contrasts. While passive quiet, it does have tube bloom (distortion?) which tube users love, but certainly not slow and colored - very neutral, not disimilar to the BENT TAP or the Atma-sphere in that sense. I'm not sure I would like it much "warmer", it seems right to me. Bass seems ample, well defined, and it breathes. My speakers have no output below 28hz, so what deep bass weakness the pre may have, I don't hear it. I go back and forth between the Dodd and the BENT TAP, and really it is a tossup though they sound a bit different - both excellent preamps. You could certainly live with the Dodd for a long time and if you let yourself, not be thinking about the next upgrade. I'll have to decide whether to keeps this or the BENT as I feel a bit silly having two preamps for my Music Reference amp - the Dodd really is beautiful to look at though....
