power conditioners, i don't do it for the s6. i did it for the whole system :)
vibration control, a weak point here. i never really do it, not that because i don't believe it. just don't have the time yet to try any. i did try with a few pucks. not working for the s6
tubes, i've been using some mullards and rcas. not the best but they do sound smooth and romanic, which is what i want, i think
cables, i've tried a few and i think my previous version...
