Doing so just pushes the problem elsewhere. The CM Spartan 3 models
are fundamentally a 75-ohm input design, so we don't sidestep balun
loss. Model versions with a 300-ohm input(s) have 4:1 internal baluns
to match the incoming line impedance. Actually IIRC every 300-input
preamp I've ever seen has had an input balun.
True, theres a 300 ohm to something matching network in there. But at least its a Channel Master build quality internal matching network. That accounts for some positive in my book.

My builds/plans (not the latest models) are located here.
