    Hi Charles

    I hate terms like 'removing a veil' 'best I have ever heard' etc, but I will try to explain the differences.

    The use of the CORRECT sorbothane feet was a revelation in terms of clarity of presentation. The rock you get when pushing the speakers is very similar to the Podiums and most people would be happy to stop there.

    The main difference between the two methods is that the sorbothane improves the speakers and the Podiums improve the speakers and the room, By this I mean that the sorbothane, because of its poorer isolation properties at the lower frequencies has very little effect on those frequencies that are transferred to the room structure.

    Because of this quietening of the room with Podiums, the presentation is quite different, everything is projected from the speakers against a noiseless background. For me, in my room, which has taken over 18 months to get sounding right this is quite a profound effect requiring a period of re-adjustment. Its definitely better SQ, but the new presentation will take a few days to acclimatise to, then I will move around my room treatments such as absorbers and diffusers.

    My summary is much as I posted earlier that, done properly, sorbothane feet get you most of the way there and you have to spend insane amounts of money to move on still further. For some of us, reaching out for the ultimate Hi Fi, that is a price worth paying. My perspective is that decoupling the room gives a more cost effective improvement on the whole system than spending that money on a single component.

    Interesting and useful information, thanks.

    I may have to settle for sorbothane at this stage though because of the new DAC I've ordered. I was very tempted by the DAC you have but ultimately settled on the new Mojo Audio Mystique X which is still being built

    OK Charles. I don't know of that DAC, but reviews are good

    I can't stress how important it is to get the right level of support with the sorbothane. If its too hard then it will not have entered into its optimum working range and if its too soft it will have passed through its optimum working range. I think I remember reading it should be be about 30% compressed so that 70% of its compression remains.

    Good luck.

    If you look at the You Tube vidoes of the Podiums, make a mental note of the amount they can sway and try to replicate that with the sorbothane. As my OBs are front loaded with weight I found 4 on the front and two on the back worked well.
