How can I connect 2 amps with 2 channels in each to the same source? Thank you.

I would like to connect my 2 similar amps (Musical Fidelity A220 & Musical Fidelity M 3si) to 1 source , using 2 channels on each amp. Thank you.

The A220 has "pre out". You should be able to connect your source to the A220 and the second amp to the "pre-out" outputs of the A220.

If you want to connect one source to both amps the simplest way is to split the audio output of the source.
If you want to connect multiple sources then kanewolfs' suggestion will be easier than splitting each one. The only issue is that the preamp out is variable. If there is a record out that will work better. It will give a fixed output.
