Pedestals do not "add" vibration. However, they certainly can amplify it if it exists. May require more careful attention to equalization of foot-loading of the machine than you're accustomed to. And installers are notoriously deficient in doing this because it takes more time than they're willing to spend. It's not all that difficult, but I doubt your installer will be willing to do it. Concrete floor install-sites are always best but MANY folks have suspended-floor installations that work fine. Suspended floor plus pedestal would have the highest likelihood of giving trouble. Do you have vibration issues with current set-up? These situations are very difficult to predict in advance. Too many variables. You may be fine or you may have issues. If you have issues you may find them easy to resolve or you may find them impossible to resolve. I encourage you to describe your concerns to the vendor before purchase and have an agreement that will allow you to exchange your chosen machine for another if you encounter an unresolvable situation. Not intending to obfuscate. In your situation, I would go ahead and do what you intend with the expectation that things will be OK or can be made OK. If it doesn't work, I'd shift gears and do something else.

It's not really easy to see in pictures because you need to take a close up shot and I don't have very good photo skills! I'll try to describe it better. On the long narrow outer corner edges of the cabinet doors or the edges of the drawer face, there are lines running down the length of the door where the wood underneath is visible. Almost like what you would see in a distressed cabinet but these aren't distressed. The sales rep said it was likely from sanding too hard on these corner edges prior to putting the clear coat on. There are mitered details on the overlay where the stain looks spattered and you can see dots of bare wood underneath. It looks hazy like when you do an initial coat of spray paint and you haven't fully covered what's underneath. Rag marks on the top edges of pullout drawers, the part that would be under the countertop. These are all things that you need to be standing close to the counter or opening a door to see them. There are aesthetic issues with some of the shaker overlay where the stiles and rails have huge variances in the color. My contractor has some experience making cabinets in the past and said he would never have put those two pieces of wood next to each other because it just looks bad but in this factory they mustn't be paying attention to that level of detail. I really wish I had gone with painted cabinets because it seems like there would be less room for error. To add another layer of frustration my glass backsplash tile is being installed and I don't think it goes very well with my countertops. I can't blame anyone else for that! The sample I had was pretty small and it didn't really show all the color variation. I'm hoping I'll like it better when it's grouted. I probably should have gone with white subway that I thought I didn't want. The tile might be my second costly mistake.

I'll add me 2 cents as well & completely agree with Live_wire_oak & Debbi. Many years ago when I was an apprentice Furniture Maker I was trained to always cut out the sap wood especially with cherry. Unfortunately, this is not a practice used by many companies now. It's become the "normal & acceptable". It never catches up with the heartwood in colour and the heartwood will darken more to create even more of a colour difference. It could have all been stained "to match" when new making it less noticeable, but over time the heartwood has darkened leaving behind the noticeable sapwood. Unfortunately, your Rep is telling you the truth. As much as it pains me to agree with it.

Should have been sanded and toned before install. You don’t ever get great work standing in a scaffold reaching overhead. A tinted clear coat (toner) in a dark should be used. Not stain. And by a true professional. Not your standard painter on site. That will never be even colored and perfect. It just can’t. It would all need to be sanded to bare wood, which is an enormous amount of very difficult labor. A dark toner is the best route forward.
