Impedance Matching Question

Most know that the input impedance of an amp needs to be ~10X the output impedance of the preamp for proper matching. Is there an inexpensive device that can be placed between a higher impedance preamp and lower impedance amp to help solve the issue? This is not for critical listening, but I do want it to sound good.

That'll work as long as it has the bandwidth.
So, is it just getting the proper transformer, 2 pair of female RCA’s, and a project box, then solder and assembly?
That would work too.

A line transformer can be used. IME, not an elegant option, but it works. You are better off with a preamp that can drive the amp properly.
