Not necessarily. It depends how you listen to music, the kind of music you like, and the sonic presentation you prefer.
Like most Denon cartridges, sonically, they punch WAY above their price point, so you can't really judge it as a £300 cartridge, as in some areas it'll outperform ones costing double (or more). Much will depend on how successfully you get the most out of it, based on what you use it with.
Unlike some others here, I'm not a fan of Ortofon's 2M range of MMs, and that includes the Black. I admire what it does in a hi-fi sense, but musically, it leaves me cold, although I can understand in Jim's system, with the T/T and arm he uses (which has a beautifully fluid and easy-going sound) and the valve amplification, that effect will be largely ameliorated.
Therefore, in summary, it just depends on what he's looking for and how he wants to go about achieving it, but it would be churlish to assume that more expensive automatically equals better, as that's not how it works with cartridges
