fiorgetting the skills for a second, a good cab is the most important, followed by a good bass, then a good amp. i've played crap basses through crap amps and great cabs and sounded like hot buttered jesus, and i've played great basses through great amps and a crap cab and sounded like ass.
the cab is the bottleneck that determines tone. if you have to skimp, skimp on anything else but the cab.
Couldn't have said it better myself.
