Looking for a 6-channel amp

I am upgrading my HT from

5.2

to

7.2.4

from 5 channels to 11 channels

I am using Golden Ear Triton One with their newer, larger centre and 2 GE in-wall for rears.

i am adding 2 sides and 4 ceiling GE speakers.

i would love to get a used 6 channel amp as the speakers are adding up.
