    I'd imagine the output stage would have the most effect on bass.

    Earthing is critical to the bass, more so than the output stage topology IMHO.

    I would have thought that John Westlake has the room / speaker / amplifier optimised so that he can quantify the sound of the equipment he is developing. It might not be to everyone's taste, as it's their for him to test and quantify. I do recall that John said the power supply was not optimised at this stage on the DevDac (it was running off a lab power supply during the test), so hopefully there is more to come from it and the bass performance. There has been talk of a valve output stage, but I would think that is for the FDAC now.

    I seem to recall that when I was trying out the multi rail Calex power supplies with the MDAC that one of the noticeable improvements it made was in the bass quality. Perhaps that indicates that the better PS in the final DevDAC (vs the bench PS) will do the trick . . .

    David Walsh[​IMG] Re: bass, I do remember Dave and I being happy with what we were hearing on that front from the MLs in our ‘jumper’ listening sessions, and John assuring us it would get even better in the next iteration.
