The distance from the front of the leading feet to the rear of the back feet is about 11 1/4". One other possible issue is that the speaker binding posts of the Bryston are not a typical 5-way post, being instead an EU-compliant device with banana connections as a normal post would have(pointing out the back of the unit) but spade/pin/bare wire connections accessed from below only (or at least, they are that way on my amplifier). Bulky speaker wire without the ability to bend easily may require you to leave the posts positioned over open space (i.e., the entire amp placed far enough back that the speaker wire can be connected directly). The distance from the leading edge of the front feet to the beginning of the binding posts is about 11 7/8". I use WBT 0645 banana plugs and have no problems, but your shelves should work fine.
