An optional internal board installed on request (and by hand in Boston) would likely cost as much as simply offering a standalone phono pre-amp, especially in a product that isn't using a card-based architecture. I seem to recall a few people suggesting that Outlaw look at tucking the RR2150's phono section into a chassis of its own for just this purpose - don't know if it will come to pass (might be a small demand, narrow margin sort of product), but it'd probably be a more efficient solution - plus it would find a wider market (since it could be paired with the 970, with any other future products that lack a phono input, or even with somebody else's product).
