Can Power mono amps be too close to the speaker

My cables are 2' and I keep my monos away by 1/2' since they have an output and power transformers that can inflict additional vibrations if fully attached onto the speaker.
Bryston Powerpack 250 for example, is designed to be attached right onto the speaker. In this case you won't even need any speaker cables -- just buy any good quality conductor and connect then directly.

As I've mentioned b4, my cable length is >2feet and amps staying on 1/2 feet distance from speakers. My speakers as well as tube monos are standing on platforms and platforms are placed on vibrapods that are highly advertised on audiomarket.

There are many options to place your monos. You can even hide them behind the wall and then thread the speaker wire through it so you can have both of the advantages of having the short runs (>1m) per each side and extra isolation.

I have a site where you can see the equipment placement and comments from owners. There are toooo many systems described there so take your time and find for yourself the best match.
