Yes - I have been running an old Audio Technica AT33 whilst my Van den hul Calibri XGW is off for service - it has really surprised me. AT33E ( elliptical ) or AT33PTGII ( micro ridge styli ) are great bang for the buck - better than the slightly more expensive OC9 series. They would be a better match than the Denon 103.
If you want high output - Soundsmith and Grado are great options.
Yes the old micro cables can be bettered at modest cost - better quality connectors and cable today. Get your cartridge choice first - if you buy a moving magnet you will want a low capacitance phono cable. If you run a moving coil then capacitance is not an issue.
