Don't know the Dyna but own both the Kansui and Shelter 901 (bought in 2001, retipped by Soundsmith around 6 years ago). The Kansui, to me, is a substantial upgrade over the Shelter, with much more body, weight, and an organic quality that is hard to find elsewhere. However, it can be a little difficult to dial-in just right for loading. I ranged from around 290 to 350R with a resistor-loaded phono stage and never felt I got it right. Best results have been using a 30X SUT (Bob's SKY 30) into MM inputs. I have it on a Graham Phantom Supreme.
