I'm just looking for feedback on the benefits of using isolation feet on a CDP. The room my stereo rack is in has a very bouncy floor and I'm wondering if this is affecting my CDP. The player doesn't skip but I can see the rack physically move when people walk past it. Most info I've found online seems to be very positive regarding adding isolation feet to components including amps and pre-amps.They suggest removing the factory feet first whenever possible. The interesting thing is some of the really cheap ones were given very good reviews.I can get a set of 4 Isonodes for $19.99 online which is obviously a very small layout if they don't make a noticable difference. I guess the reason I'm doubtful is if inexpensive isolation feet really improve sound noticably why would players such as my $700 Arcam 73T not come with them in stock form.Maybe the only worthy ones cost big money so they can't throw them in. It's just weird because the Isonodes got cudos from some very reputable sources. I'll probably just buy them for $20 and that way if they don't make a big difference it's no big loss. If I spent $150 a set I would have very high expectations and would really be pissed if they didn't help. I'm also torn on whether to put them on my amp and pre-amp.Thanks in advance for any feedback.
