Where would you place Symposium Rollerblocks for best results on digital equipment?


I am seeking advice for the best placement benefit for Symposium Rollerblocks on my digital equipment?  Would the CD Transport and player be the best place or since I have a separate upsampler and DAC would that be the best place to place them, since they lead into my integrated amplifier?

Honestly, let your ears be your guide here and experiment! Keep what sounds best to you. You will get differing opinions here I'm sure, but only your ears matter!

You might want to put some Felt under you DAC too... It would be helpful to give us an idea of what components you have in you system...
