Denon DL-S1 and ASR Mini Basis phono on Rega RP6?

What do people think of this combo? It seems to fall in the optimal resonance frequency range (although Rega doesn't list effective mass for the RB303 arm i'm guessing around 11 or 12g). The DL-S1 needs a lot of gain and the ASR Mini Basis has adjustable gain up to 70dB as well as lots of loading options. I'm guessing I would need to use a spacer to achieve correct VTA but that's no big deal.
